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 Binaries were compiled on RHEL5.5 The Dell PowerEdge T710 and the Bull NovaScale T860 F2 models are electronically equivalent. The results have been measured on a Dell PowerEdge T710 model
