Efficient code does not depend on how you handle it (git, svn or tarballs or whatever). And I don't think different practices is the real reason why Giac was/is mostly ignored here.
After having done a few tests, I think I know why my code on Q is slower with more threads (if the number of threads exceeds say 2 or 3), it is related to the size of memory the various cores have to acces more than allocation locks, this size is proportionnal to the number of threads if each thread does a different modular computation, and this raises much more cache misses. Which means I must parallelize in each modular computation instead of doing different modulus in parallel. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
