Operating System Notes
'ulimit -s unlimited' was used to set the stacksize to unlimited prior to run 'mount -t hugetlbfs nodev /mnt/hugepages' was used to enable large pages echo 900 > /proc/sys/vm/nr_hugepages export HUGETLB_MORECORE=yes export LD_PRELOAD=/usr/lib64/libhugetlbfs.so
Platform Notes
BIOS Settings: Power Management = Maximum Performance (Default = Active Power Controller) Data Reuse = Disabled (Default = Enabled) Logical Processor = Disabled (Default = Enabled)
General Notes
OMP_NUM_THREADS set to number of cores The Dell PowerEdge R510 and the Bull NovaScale R450 F2 models are electronically equivalent. The results have been measured on a Dell PowerEdge R510 model. Binaries were compiled on RHEL5.5
