Alternate sources:
Required srcalt=purdue1 is applied to 330.art_m (base & peak) for correctness.
Peak sources:
Optional SPEC OMPL2001 source for 32bit systems (modified for SPEC OMPM2001) was
SMT: Acronym for "Simultaneous Multi-Threading". A processor technology that allows
the simultaneous execution of multiple thread contexts within a single processor
core. (Enabled by default)
DCM: Acronym for Acronym for "Dual-Chip Module" (one dual-core processor chip + one L3-cache chip)
ESSL: Engineering and Scientific Subroutine Library
SUT: Acronym for "System Under Test"
C: IBM XL C for AIX invoked as xlc_r
Fortran: IBM XL Fortran for AIX invoked as xlf90_r
ulimits set to unlimited.
