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.
The installed Fortran copiler is XL Fortran Enterprise Edition Version 10.1 with the May 2006 AIX 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=128 -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 = bindprocessor \$\$ \$SPECUSERNUM; $command
The "bindprocessor" AIX command binds a process to a CPU core.
Three cores were deconfigured and SMT disabled using the AIX commands
smtctl -m off -w boot
bosboot -aD
shutdown -rF
drmgr -r -c cpu
drmgr -r -c cpu
drmgr -r -c cpu
This result was measured on an IBM System p5 505Q. IBM System p5 505Q and IBM System
p5 520Q are electronically equivalent.
