Are there constraints on the number of *active* nodes in Termite? The reason I ask is that while I can create many nodes on the same machine, I can only remote-spawn to one other node (I am using a dual core machine). For example, using the code included (which is a bit odd because I have pulled code out of libraries to make a simple demo), the following is ok (with a single node) : gsi test.scm ((1 a) (2 b) (3 c) (1 d)) ("acp-make-nodes" #<node #2 ip: "localhost" port: 30000> ok) ("acp-map spawn" #<node #2 ip: "localhost" port: 30000>) ("acp-map spawn" #<node #2 ip: "localhost" port: 30000>) ("acp-map spawn" #<node #2 ip: "localhost" port: 30000>) ("acp-map spawn" #<node #2 ip: "localhost" port: 30000>) ("acp-map recv" #<thread #3>) ("acp-map recv" #<thread #4>) ("acp-map recv" #<thread #5>) ("acp-map recv" #<thread #6>) (2 3 4 5) but with two nodes created i see: : gsi test.scm ((1 a) (2 b) (3 c) (1 d)) ("acp-make-nodes" #<node #2 ip: "localhost" port: 30000> ok) ("acp-make-nodes" #<node #3 ip: "localhost" port: 30001> ok) ("acp-map spawn" #<node #3 ip: "localhost" port: 30001>) ("acp-map spawn" #<node #2 ip: "localhost" port: 30000>) ------------- REPL is now in #<thread #4> ------------- *** INTERRUPTED IN ##wait-for-io! (where I hit Ctrl-C after it hung) Any help appreciated - the enclosed file should run the first case above. To see the second change the appropriate line to (nodes (acp-make-nodes (list "localhost") 30000 2 #f))) - ie the penultimate arg is the number of nodes. Thanks, Andrew
