Re: No word on where you can obtain this P4- optimized version of gcc, though. Re: Intel generates its bogus SPEC scores by using their compiler to opt out of the bogus algorithms SPEC insists on everyone running - unless they want to create an entire compiler to optimize out the bogus code. They probably do something similar with gcc - check out this discussion... WHAT ABOUT SPEC FP 2000. Why the pooor... incredibly poor memory management. Does this have to do with NOT USING OPTIMIZED BLAS. Yes.. the folks at spec in their infinite wisdom have chosen to put the BLAS source in the benchmarks themsleves and then renamed the routines. Dgemm isn't dgemm anymore but something else. This was told to me by one of the people at spec and on the board of spec. Only 2 benchmarks out of the 14 can actually be linked to with external optimzied BLAS binaries. The others.. well you are ... really out of luck. What does this do to perf. Here it is: DGEMM Source Compiled: w3.physics.uiuc.edu ==> ~100 MFLOPS DGEMM OPTIMIZED IN ATLAS(www.netlib.org/atlas/archives IT'S FREE): w3.physics.uiuc.edu. ==> 1400 MFLOPS aceshardware.com
