Supermicro HFT Low Latency / Jitter OS Optimization
This set up was designed for the SYS-6027AX-72RF/TRF-HFT3, however it will help all othe HFT systems.
System Setup
- Fresh Minimal Install fof SL / RHEL 6.4
- OS Boot parameters: intel_idle.max_cstate0= processor.max_cstate=0 idle=poll pcie_aspm=performance mce=ignore_ce, isolcpus=2,3,4
- Configure a noatime or OS parition
- Disable all unnecessary services using chkconfig command
- Install CPUpower, tuned, tuna
- sysctl kernel.sched_wakeup_granularity_ns=3000000
System Tuning
- modprobe acpi-cpufreq
- cpupower set-perf bias 0
- cpupower frequency-set-governor performance
- tuned-adm profile latency-performance
- tuna -S0 -i; tuna -S1 -i
- Use taskset or numactl to bind application to specific CPU core
