Maximizing Performance involves “System Level” optimizations
● OEM BIOS Settings: SMI, HyperThreading, C-States- All Off
- Experiment with EIST & Turbo On/Off
● On the application: Maximize your resources by…
- Pin Threads, Interrupts, and Processes to individual cores using
CPU_ID
- Place “communication” functions threads on adjacent cores
- Use PCM to determine L3 Cache Misses & Keep data in L3 Cache

- Compile w/Performance Settings, Use PGO, Evaluate IPP / SSE 4.2
Strings

● Determine how many cores your trading strategy requires
- Can it run on 8 cores? If so, match up CPU+NIC per strategy
