Submit Notes
The config file option 'submit' was used. taskset was used to bind processes to cores except for 462.libquantum peak
Operating System Notes
'ulimit -s unlimited' was used to set the stack size to unlimited prior to run
Platform Notes
BIOS Settings: Adjacent Cache Line Prefetch = Disabled (Default = Enabled) Hardware Prefetcher = Disabled (Default = Enabled)
General Notes
