Hi all, today Alex Best started in Kaiserslautern on this OpenDreamKit project. He's working on support in MPIR for the latest Intel and AMD processors. However, we have very little access to anything later than about 2010.
Does anyone have more recent Intel and AMD machines (linux servers) that they could provide log in access to? We'd be doing timings of all the basic MPIR functions and eventually superoptimising the assembly language functions. In general, one can expect up to a 2x speedup for each different microarchitecture (code from previous arches is rarely anywhere near optimal for more recent ones). E.g. we just tried some code which is roughly optimal for bobcat on a piledriver and it was two times slower than the old K10 code we have! If you can help, please contact me off list. Bill. P.S: We are aware of the GCC farm, but almost everything there we have access to elsewhere. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
