Hello, on a simple task - multiply two matrices mat_a and mat_b https://github.com/glathoud/flatorize/blob/master/explore/scheme_matmul_comm... - I've been comparing 3 implementations, using interpretation and compilation. To compile I used the line below. Is there a better way, at least a few straightforward optimization (options) ? gsc -exe -o scheme_matmul_classic.bin tmp.scmDetails are below. Best regards, Guillaume 1. Functional implementation: https://github.com/glathoud/flatorize/blob/master/explore/scheme_matmul_list... 2. Ugly imperative implementation: https://github.com/glathoud/flatorize/blob/master/explore/scheme_matmul_clas... 3. Flat implementation (for the specific matrix sizes): https://github.com/glathoud/flatorize/blob/master/explore/scheme_matmul342.s... To run both tests (interpreted and compiled), I used this: https://github.com/glathoud/flatorize/blob/master/explore/scheme_matmul.sh#L...
