Gambit versus Python+GMP: Timing for Chudnovskys' algorithm for pi
by Bradley Lucier 07 Avr '22

07 Avr '22

Bakul Shah wrote a particularly elegant Scheme program for Chudnovskys' algorithm for pi based on the Common Lisp program here: https://bitbucket.org/tarballs_are_good/numericl/src/5fe8fe7089f48ab1c8a388… Nick Craig-Wood wrote a Python program using the GMP multiprecision library that appears to use exactly the same algorithm here: http://www.craig-wood.com/nick/articles/pi-chudnovsky/ I modified both programs a bit and include them here. They time the calculation of $10^n$ digits of pi for $n=1,2,3,4,5,6,7$. The results are heine:~/programs/gambiteer/gambit> !py python pi_chudnovsky_bs_gmpy.py 31415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679 ('chudnovsky_gmpy_mpz_bs: digits', 10, 'time', 1.0967254638671875e-05) ('chudnovsky_gmpy_mpz_bs: digits', 100, 'time', 3.0040740966796875e-05) Last 5 digits 70679 OK ('chudnovsky_gmpy_mpz_bs: digits', 1000, 'time', 0.00025582313537597656) Last 5 digits 01989 OK ('chudnovsky_gmpy_mpz_bs: digits', 10000, 'time', 0.00386810302734375) Last 5 digits 75678 OK ('chudnovsky_gmpy_mpz_bs: digits', 100000, 'time', 0.0834801197052002) Last 5 digits 24646 OK ('chudnovsky_gmpy_mpz_bs: digits', 1000000, 'time', 1.655979871749878) Last 5 digits 58151 OK ('chudnovsky_gmpy_mpz_bs: digits', 10000000, 'time', 30.67442488670349) Last 5 digits 55897 OK heine:~/programs/gambiteer/gambit> gsi chud1.scm Chudnovsky's algorithm using binary splitting in Gambit Scheme: digits 10, CPU time: 0..

So it appears that for this algorithm applied to large integers, GMP's bignum routines are about 3-4 times as fast as Gambit's bignum routines. Not so bad. For smaller bignums, GMP has a bigger advantage. The C program gmp-chudnovsky.c includes certain optimizations to this basic algorithm: http://gmplib.org/pi-with-gmp.html ftp://ftp.gmplib.org/pub/misc/gmp-chudnovsky.c On my machine, compiled with gcc -O3 -march=native -o gmp-chudnovsky gmp-chudnovsky.c -lgmp -lm the CPU times for 1,000,000 and 10,000,000 digits are 1.064 and 18.200 seconds, respectively. This is with a somewhat older machine model name : Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz running Ubuntu 13.04 with heine:~/programs/gambiteer/gambit> gcc -v Using built-in specs.

Gambit at 30
by Marc Feeley 19 Jul '19

19 Jul '19

This year is the 30th anniversary of Gambit. To mark the occasion I am planning to organize a 1-2 day meeting this fall in Montreal if enough people can attend. The content remains to be determined but I can imagine some more-or-less formal presentations by me and attendants, brainstorming sessions and maybe some hacking on Gambit. To maximize attendance the meeting will be on a weekend, probably in September or October. So please let the list know if you are interested in attending, and if you have preferences for the date. Also please indicate if you are interested in giving a presentation (15-30 minutes or more if you have lots of material) or organize some other activity. Marc

magnitude vs hypot
by Bradley Lucier 30 Mar '19

30 Mar '19

This is getting pretty deep into the internals, but ... I was thinking of replacing my implementation of ##cabs (complex absolute value) in _num.scm with glibc's hypot. Turns out that ##cabs (which is based on one of Kahan's papers) returns the correctly-rounded answer more often than hypot (which Kahan also had a hand in): Here's a count of how many times hypot and magnitude returned answers that were off by between 1/2 and 1 ulp: > (time (test 100000)) (n: 100000 hypot-errors: 12906 magnitude-errors: 4557) (time (test 100000)) 3.600013 secs real time 3.599883 secs cpu time (3.592672 user, 0.007211 system) 401 collections accounting for 0.047208 secs real time (0.047259 user, 0.000060 system) 1942508792 bytes allocated no minor faults no major faults These shouldn't really be called "errors" just because they have slightly bigger than optimal floating-point errors. The correctly-rounded answers were computed using my computable reals package. I haven't yet compared computation speed, but it appears I'll leave ##cabs as is. This is on Ubuntu 18.04 on x86-64.

Topics relevant to SLE cover generic aspects of software languages development rather than aspects of engineering a specific language. In particular, SLE is interested in contributions from the following areas: * Software Language Design and Implementation - Approaches to and methods for language design - Static semantics (e.g., design rules, well-formedness constraints) - Techniques for specifying behavioral / executable semantics - Generative approaches (incl. code synthesis, compilation) - Meta-languages, meta-tools, language workbenches * Software Language Validation - Verification and formal methods for languages - Testing techniques for languages - Simulation techniques for languages * Software Language Integration and Composition - Coordination of heterogeneous languages and tools - Mappings between languages (incl. transformation languages) - Traceability between languages - Deployment of languages to different platforms * Software Language Maintenance - Software language reuse - Language evolution - Language families and variability * Domain-specific approaches for any aspects of SLE (design, implementation, validation, maintenance) * Empirical evaluation and experience reports of language engineering tools - User studies evaluating usability - Performance benchmarks - Industrial applications --------------------------- Important Dates --------------------------- All dates are Anywhere on Earth. * Fri 14 Jun 2019 - Abstract Submission * Fri 21 Jun 2019 - Paper Submission * Fri 9 Aug 2019 - Author Notification * Fri 16 Aug 2019 - Artifact Submission * Fri 30 Aug 2019 - Artifact Kick-the-tires Author Response (7 days) * Fri 20 Sep 2019 - Camera ready deadline * Wed 25 Sep 2019 - Artifact notification * Fri 27 Sep 2019 - Artifact-related paper updates * Mon-Tue 21-22 Oct 2018 - SLE Conference --------------------------- Types of Submissions --------------------------- SLE 2019 solicits three types of contributions: Research Papers, Tools Papers, and New Ideas/Vision papers. * Research papers These should report a substantial research contribution to SLE or successful application of SLE techniques or both. Full paper submissions must not exceed 12 pages, excluding bibliography. * Tool papers Because of SLE’s interest in tools, we seek papers that present software tools related to the field of SLE. Selection criteria include originality of the tool, its innovative aspects, and relevance to SLE. Any of the SLE topics of interest are appropriate areas for tool demonstrations. Submissions must provide a tool description of 4 pages excluding bibliography, and a demonstration outline including screenshots of up to 6 pages. Tool demonstrations must have the keywords “Tool Demo” or “Tool Demonstration” in the title. The 4-page tool description will, if the demonstration is accepted, be published in the proceedings. The 6-page demonstration outline will be used by the program committee only for evaluating the submission. *New ideas / vision papers New ideas papers should describe new, non-conventional SLE research approaches that depart from standard practice. They are intended to describe well-defined research ideas that are at an early stage of investigation. Vision papers are intended to present new unifying theories about existing SLE research that can lead to the development of new technologies or approaches. New ideas / vision papers must not exceed 4 pages, excluding bibliography. *Workshops Workshops will be organized by SPLASH. Please inform us and contact the SPLASH organizers if you would like to organize a workshop of interest to the SLE audience. Information on how to submit workshops can be found at the SPLASH 2019 Website. --------------------------- Artifact Evaluation --------------------------- SLE will continue to use an evaluation process for assessing the quality of the artifacts on which papers are based to foster the culture of experimental reproducibility. Authors of accepted papers are invited to submit artifacts. For more information, please have a look at the Artifact Evaluation page. --------------------------- Submission Details --------------------------- Paper Format: Submissions must conform to the ACM SIGPLAN Conference Format “acmart”; please make sure that you always use the latest ACM SIGPLAN acmart LaTeX template, and that the document class definition is \documentclass[sigplan,screen]{acmart}. Do not make any changes to this format! Using the Word template is strongly discouraged. Ensure that your submission is legible when printed on a black and white printer. In particular, please check that colors remain distinct and font sizes in figures and tables are legible. To increase fairness in reviewing, a double-blind review process has become standard across SIGPLAN conferences. For the first time, SLE will follow the double-blind process. Author names and institutions should be omitted from submitted papers, and references to the authors’ own related work should be in the third person. No other changes are necessary, and authors will not be penalized if reviewers are able to infer their identities in implicit ways. All submissions must be in PDF format. Concurrent Submissions: Papers must describe unpublished work that is not currently submitted for publication elsewhere as described by SIGPLAN’s Republication Policy. Submitters should also be aware of ACM’s Policy and Procedures on Plagiarism. Submissions that violate these policies will be desk-rejected. Submission Site: Submissions will be accepted at https://sle19.hotcrp.com/ --------------------------- Reviewing Process --------------------------- All submitted papers will be reviewed by at least three members of the program committee. Research papers and tool papers will be evaluated concerning novelty, correctness, significance, readability, and alignment with the conference call. New ideas / vision papers will be evaluated primarily concerning novelty, significance, readability, and alignment with the conference call. For fairness reasons, all submitted papers must conform to the above instructions. Submissions that violate these instructions may be rejected without review, at the discretion of the PC chairs. --------------------------- Awards --------------------------- * Distinguished paper: Award for most notable paper, as determined by the PC chairs based on the recommendations of the programme committee. * Distinguished reviewer: Award for distinguished reviewer, as determined by the PC chairs. * Distinguished artifact: Award for the artifact most significantly exceeding expectations, as determined by the AEC chairs based on the recommendations of the artifact evaluation committee. --------------------------- Publication --------------------------- All accepted papers will be published in the ACM Digital Library. AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference.

Gambit compiler is deterministic right?
by Adam 15 Mar '19

15 Mar '19

Hi Marc, Gambit's compiler is deterministic right? (As in Scheme to GVM, GVM to C or binary. Underlying C compiler's determinism is a separate matter altogether.) A consideration could be that compilation output is a function of |gensym| and therefore its counter must be managed for deterministic compilation. Another consideration that if running more instances of the compiler in one Gambit process concurrently, the |gensym| calls could have arbitrary order and therefore determinism break. Adam

-------------------------------- 2 N D C A L L F O R P A P E R S -------------------------------- ====== TFP 2019 ====== 20th Symposium on Trends in Functional Programming 12-14 June, 2019 Vancouver, BC, CA https://www.tfp2019.org/index.html == Important Dates == Submission Deadline for pre-symposium formal review Thursday, March 28, 2019 Sumbission Deadline for Draft Papers Thursday, May 9, 2019 Notification for pre-symposium submissions Thursday, May 2, 2019 Notification for Draft Papers Tuesday, May 14, 1029 TFPIE Tuesday, June 11, 2019 Symposium Wednesday, June 12, 2019 – Friday, June 14, 2019 Notification of Student Paper Feedback Friday June 21, 2019 Submission Deadline for revised Draft Papers (post-symposium formal review) Thursday, August 1, 2019 Notification for post-symposium submissions Thursday, October 24, 2019 Camera Ready Deadline (both pre- and post-symposium) Friday, November 29, 2019 The symposium on Trends in Functional Programming (TFP) is an international forum for researchers with interests in all aspects of functional programming, taking a broad view of current and future trends in the area. It aspires to be a lively environment for presenting the latest research results, and other contributions (see below at scope). Please be aware that TFP uses two distinct rounds of submissions (see below at submission details). TFP 2019 will be the main event of a pair of functional programming events. TFP 2019 will be accompanied by the International Workshop on Trends in Functional Programming in Education (TFPIE), which will take place on June 11. == Scope == The symposium recognizes that new trends may arise through various routes. As part of the Symposium's focus on trends we therefore identify the following five article categories. High-quality articles are solicited in any of these categories: Research Articles: Leading-edge, previously unpublished research work Position Articles: On what new trends should or should not be Project Articles: Descriptions of recently started new projects Evaluation Articles: What lessons can be drawn from a finished project Overview Articles: Summarizing work with respect to a trendy subject Articles must be original and not simultaneously submitted for publication to any other forum. They may consider any aspect of functional programming: theoretical, implementation-oriented, or experience-oriented. Applications of functional programming techniques to other languages are also within the scope of the symposium. Topics suitable for the symposium include, but are not limited to: Functional programming and multicore/manycore computing Functional programming in the cloud High performance functional computing Extra-functional (behavioural) properties of functional programs Dependently typed functional programming Validation and verification of functional programs Debugging and profiling for functional languages Functional programming in different application areas: security, mobility, telecommunications applications, embedded systems, global computing, grids, etc. Interoperability with imperative programming languages Novel memory management techniques Program analysis and transformation techniques Empirical performance studies Abstract/virtual machines and compilers for functional languages (Embedded) domain specific languages New implementation strategies Any new emerging trend in the functional programming area If you are in doubt on whether your article is within the scope of TFP, please contact the TFP 2019 program chairs, William J. Bowman and Ron Garcia. == Best Paper Awards == To reward excellent contributions, TFP awards a prize for the best paper accepted for the formal proceedings. TFP traditionally pays special attention to research students, acknowledging that students are almost by definition part of new subject trends. A student paper is one for which the authors state that the paper is mainly the work of students, the students are listed as first authors, and a student would present the paper. A prize for the best student paper is awarded each year. In both cases, it is the PC of TFP that awards the prize. In case the best paper happens to be a student paper, that paper will then receive both prizes. == Instructions to Author == Papers must be submitted at: https://easychair.org/conferences/?conf=tfp2019 Authors of papers have the choice of having their contributions formally reviewed either before or after the Symposium. == Pre-symposium formal review == Papers to be formally reviewed before the symposium should be submitted before an early deadline and receive their reviews and notification of acceptance for both presentation and publication before the symposium. A paper that has been rejected in this process may still be accepted for presentation at the symposium, but will not be considered for the post-symposium formal review. == Post-symposium formal review == Papers submitted for post-symposium review (draft papers) will receive minimal reviews and notification of acceptance for presentation at the symposium. Authors of draft papers will be invited to submit revised papers based on the feedback received at the symposium. A post-symposium refereeing process will then select a subset of these articles for formal publication. == Paper categories == There are two types of submission, each of which can be submitted either for pre-symposium or post-symposium review: Extended abstracts. Extended abstracts are 4 to 10 pages in length. Full papers. Full papers are up to 20 pages in length. Each submission also belongs to a category: research position project evaluation overview paper Each submission should clearly indicate to which category it belongs. Additionally, a draft paper submission—of either type (extended abstract or full paper) and any category—can be considered a student paper. A student paper is one for which primary authors are research students and the majority of the work described was carried out by the students. The submission should indicate that it is a student paper. Student papers will receive additional feedback from the PC shortly after the symposium has taken place and before the post-symposium submission deadline. Feedback is only provided for accepted student papers, i.e., papers submitted for presentation and post-symposium formal review that are accepted for presentation. If a student paper is rejected for presentation, then it receives no further feedback and cannot be submitted for post-symposium review. == Format == Papers must be written in English, and written using the LNCS style. For more information about formatting please consult the Springer LNCS web site (http://www.springer.com/lncs). == Program Committee == Program Co-chairs William J. Bowman University of British Columbia Ronald Garcia University of British Columbia Matteo Cimini University of Massachusetts Lowell Ryan Culpepper Czech Technical Institute Joshua Dunfield Queen's University Sam Lindley University of Edinburgh Assia Mahboubi INRIA Nantes Christine Rizkallah University of New South Wales Satnam Singh Google AI Marco T.

Examples of evidence include formalizations and proofs, implemented systems, experimental results, statistical analyses, and case studies. * Clarity. The paper must present its contributions and results clearly. PAPER CATEGORIES GPCE solicits three kinds of submissions. * Full Papers reporting original and unpublished results of research that contribute to scientific knowledge in any GPCE topic listed above. Full paper submissions must not exceed 12 pages excluding bibliography. * Short Papers presenting unconventional ideas or visions about any GPCE topic listed above. Short papers do not always require complete results as in the case of a full paper. In this way, authors can introduce new ideas to the community and get early feedback. Please note that short papers are not intended to be position statements. Short papers are included in the proceedings and will be presented at the conference. Short paper submissions must not exceed 6 pages excluding bibliography. * Tool Demonstrations presenting tools for any GPCE topic listed above. Tools must be available for use and must not be purely commercial. Submissions must provide a tool description not exceeding 6 pages excluding bibliography and a separate demonstration outline including screenshots also not exceeding 6 pages. Tool demonstrations must have the keywords "Tool Demo" or "Tool Demonstration" in their title. If the submission is accepted, the tool description will be published in the proceedings. The demonstration outline will only be used by the program committee for evaluating the submission. PAPER SUBMISSION All submissions must use the ACM SIGPLAN Conference Format "acmart", using the "sigplan" sub-format, and 10 point font. Additional details and links to templates and the LaTeX class file can be found on the conference web site: https://conf.researchr.org/home/gpce-2019. To increase fairness in reviewing, a double-blind review process has become standard across SIGPLAN conferences. GPCE will follow a very lightweight model, where author identities are revealed to reviewers after submitting their initial reviews. Hence, the purpose is not to conceal author identities at all cost, but merely to provide reviewers with an unbiased first look at a submission. Author names and institutions should be omitted from submitted papers, and references to the authors' own related work should be in the third person. No other changes are necessary, and authors will not be penalized if reviewers are able to infer their identities in implicit ways. Papers must be submitted using HotCRP: https://gpce19.hotcrp.com/ For additional information, clarification, or answers to questions please contact the program co-chairs.
