3.9.2Guys,
I have released 3.9.2. If you are presently using 3.8 on a Core2-based system of any sort, you may want to consider trying 3.9.2: I believe it should be something like 15% faster for all types/precisions. 3.9.2 also fixes several bugs in 3.9.1, including a nasty one that causes a recursive Make dependence to hang the install (and consume all your resources). If you use QR, that has gotten another 15-20% faster on top of the BLAS speedup, due to the LAPACK tuning . . . It's just a developer release, but since I think Core2-based systems may want to use it, I have run the full ATLAS tester on both 32 and 64-bit Core2 installs, and it passed. I will probably backport the new Core2 (and K10h) kernels back to 3.8 eventually, but it may take a while before I have the time (school is about to start back up) . . . The Changelog is below. Cheers, Clint ATLAS 3.9.2 released 08/09/08, Changes from 3.9.1: * Improved Core2 performance, particularly for 32 bit and/or single precision * Changed Core2Duo arch name to Core2, since we use this description for the entire Core2 family (including Xeon, Core2Quad, etc). * Bug fixes: - Fixed cycle of dependencies in L1 Makefiles causing an endless stack of make processes (wt assoc hang) to spawn when tuning the L1 BLAS - Fixed compile probs for archs w/o cacheline flush in assembly - Fixed error in configure caused by change in CPUID usage - Added missing f77 wrappers for GERQF and GEQLF - Avoided CPP division in assembly on Solaris, due to binutils/solaris bug ************************************************************************** ** R.
