cpustat can tell you the usage of FP ops, you can follow the instructions on p35 in:
"Developing and Tuning Applications on UltraSPARC T1 Chip Multithreading Systems" BTW, I wrote most of the tuning section for T1/T2 on wikipedia, you may find some useful information there: http://en.wikipedia.org/wiki/UltraSPARC_T1#Application_tuning Rayson On 5/20/08, Krzys <[EMAIL PROTECTED]> wrote: > > Hello folks, I have an issue where developer wrote a code and it runs 10 > seconds > on his PC, then he moved it to T2000 (16GB RAM, 1.2GHz, 8 CORE, Solaris 10) > and > the same process took 73 seconds.
