  1. ORC Performance on Itanium/Linux • Testing environment: • HP i2000 WS: 733 MHz Itanium, 2M L3 Cache, 1G Mem, RH 7.2 • Compiled with SPEC base options for Ecc 7.0 and –O3 for Gcc 3.1 • Linked with standard libraries on Linux • ORC 2.1 on par with ECC 7.0 and 30% ahead of Gcc 3.1

  2. How to get the ORC peak performance? • Options for the three passes of compilation: • 1st pass: "-O3 -fb_create fb.mid -fb_type=1 -fb_phase=0 –ipa -itanium" • For eon: "-O3 -fb_create fb.mid -fb_type=1 -fb_phase=0 -INLINE:none -itanium" • 2nd pass: "-O3 -fb_opt fb.mid -fb_create fb.mid -fb_type=10 -fb_phase=4 –ipa -itanium" • 3rd pass: "-O3 -fb_opt fb.mid –ipa -itanium” • Compilation options specified by SPEC are not listed here. • Additional options may be needed for different configurations.
