As I mentioned here, Joe Mario and I delivered this session at Red Hat's Developer Exchange session in Boston. There were a lot of great questions and we hope you'll find this video-recorded session useful.
Now that you followed all the steps to make your application NUMA-aware, how do you know if you got it right, or if you shifted your performance problem elsewhere?
In this session, Don and Joe will:
- discuss initial high level steps to verify correct memory and cpu-process placement, including:
- showing how performance can easily suffer with incorrect placement.
- describing available options to correct placement.
- discuss the open source tools, both available now and in development, which use the hardware's performance counters to more accurately pinpoint:
- where your program is making costly remote NUMA memory accesses,
- identifying if and where other programs are inflicting NUMA-related performance penalties on your program,
- how much those remote accesses are hurting your performance.
- discuss various approaches for resolving these low-level issues.
If you are somewhat new to NUMA programming, take a look at this 5-part video series: Introduction to NUMA programming. Just select the "Using NUMA" section.
We hope you enjoy this recorded session!
