The installed OS level is AIX 5L for POWER version 5.3 with the 5300-03 Recommended Maintenance package.
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 "Dual-Chip Module" (one dual-core processor chip + one L3-cache chip)
SUT: Acronym for "System Under Test"
ESSL: Engineering and Scientific Subroutine Library
Extended C: IBM XL C for AIX invoked as cc
ANSI C89: IBM XL C for AIX invoked as xlc
Fortran 77: IBM XL Fortran for AIX invoked as xlf90 unless explicitly reassigned
Fortran 90: IBM XL Fortran for AIX invoked as xlf
ulimits set to unlimited.
Large page mode and memory affinity were set as follows:
vmo -r -o lgpg_regions=400 -o lgpg_size=16777216
chuser capabilities=CAP_BYPASS_RAC_VMM,CAP_PROPAGATE $USER
reboot -q
export MEMORY_AFFINITY=MCM
The following config-file entry was used to assign each benchmark process to a core:
submit = let "MYCPU=2*\$SPECUSERNUM"; if (("\$MYCPU > 3")) then let "MYCPU-=3"; fi; bindprocessor \$\$ \$MYCPU; $command
The "bindprocessor" AIX command binds a process to a CPU core.
One core was deconfigured and SMT disabled at the open-firmware prompt, using the
command
boot -s cpu=1 -s smt_off
