NUMA - Verifying it's not hurting your application performance [video]
Don Zickus
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. Abstract: 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...
Dive deeper in NUMA systems
Don Zickus
A common performance related issue we are seeing is how certain instructions are causing bottlenecks. Sometimes it just doesn't make sense. Especially when it involves lots of threads or shared memory on NUMA systems. For quite awhile a bunch of us have been writing tools to help exploit features of the CPU to provide us insight to not only the instruction of the bottleneck but the data address too. See, the instruction is only half the picture. Having the data...
