The installed OS level is AIX 5L for POWER Version 5.3 with the 5300-05 Recommended Technology Level.
The installed C/C++ compiler is XL C/C++ Enterprise Edition Version 8.0 for AIX with the March 2006 PTF.

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)
SUT: Acronym for "System Under Test"
ESSL: Engineering and Scientific Subroutine Library
PTF: IBM identifier for "Program Fix Level"
ANSI C89: IBM XL C for AIX invoked as xlc
Fortran 77: IBM XL Fortran for AIX invoked as xlf90
Fortran 90: IBM XL Fortran for AIX invoked as xlf90
ulimits set to unlimited.
Large page mode and memory affinity were set as follows:
vmo -r -o lgpg_regions=8192 -o lgpg_size=16777216
chuser capabilities=CAP_BYPASS_RAC_VMM,CAP_PROPAGATE $USER
bosboot -aD
shutdown -rF
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 > 127")) then let "MYCPU-=127"; fi; bindprocessor \$\$ \$MYCPU; $command
The "bindprocessor" AIX command binds a process to a CPU core.
Sixty-three cores were deconfigured and SMT disabled at the open-firmware prompt, using the command
boot -s cpu=1 -s smt_off
