Armin,
Wim's reply is not helpful at all for me, as it is mostly given as a series of three-letter acronyms I've never heard about :-)
well, what Yury said. :) Sorry, but I was replying to an Intel guy ... To first order, think of it as a server that you ssh to, and then you find yourself on a perfectly ordinary Linux machine, albeit one that presents you with 240 "cpus." For the current generation, you have to deal with cross-compilation, b/c its vector instruction set is unique. Beyond that, it's just x86. (The next generation uses AVX-512, so no more cross-compilation necessary.) Since PyPy does not generate vector instructions (nor deals with any offloading), the easiest I found was to generate C, and cross-compile that, all on the host; not try to run the translator on the Phi. Even so, I didn't find anything worthwhile: loosing vectorization is okay (for high energy physics codes, as they're too branchy anyway), but you really need to be able to scale out. Btw., we're in big for its successor: https://www.nersc.gov/users/computational-systems/cori/ Best regards, Wim -- wlavrij...@lbl.gov -- +1 (510) 486 6411 -- www.lavrijsen.net _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
