Operating System Notes
'ulimit -s unlimited' was used to set the stacksize to unlimited prior to run
Hugepages was enabled with the following:
'nodev /mnt/hugepages hugetlbfs defaults 0 0' added to /etc/fstab
echo 900 > /proc/sys/vm/nr_hugepages
export HUGETLB_MORECORE=yes
export LD_PRELOAD=/usr/lib64/libhugetlbfs.so
Platform Notes
Load Default BIOS Settings and then change the following Hardware Prefetch Enabled Adjacent Cache Line Prefetch Enabled L1 Data Prefetch Enabled Data Reuse Optimization Enabled Intel Hyperthreading Options Disabled
General Notes
OMP_NUM_THREADS set to number of cores KMP_AFFINITY set to granularity=fine,scatter Binaries were compiled on RHEL5.5 with Binutils binutils-2.17.50.0.6-14.el5 This result is measured on Sun Fire X4170 M2 server. Note that the Sun Fire X4170 M2 server and Sun Fire X4270 M2 server are electrically equivalent.
