if this issue disqualifies accelerate, it also disqualifies openblas as a default. openblas has the same issue, we stuck a big fat warning into the docs (site.cfg) for this now as people keep running into it. openblas is also a little dodgy concerning stability, in the past it crashed constantly on pretty standard problems, like dgemm on data > 64 mb etc. While the stability has improved with latest releases (>= 0.2.9) I think its still too early to consider openblas for a default. multithreaded ATLAS on the other hand seems works fine, at least I have not seen any similar issues with ATLAS in a very long time. Building optimized ATLAS is also a breeze on Debian based systems (see the README.Debian file) but I admit it is hard on any other platform. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
