Hello,
I have a program that spawns a number of julia processes and runs some code on them. The code uses @async
in a way that is similar to the sample pmap code in the julia documentation. The problem that I am seeing is that half the processes complete in the expected amount of time, but the other half take more than 5x the time. I am on a server machine with dual processors (each processor has 8 cores), NUMA enabled, hyperthreading disabled, and running Windows 10 (Hyper V host, no VMs running).
Are there any gotchas to using Julia and spawning Julia processes in a dual processor NUMA setting?
Thanks,
Ritchie
