Multithreding causing system crashes on linux
Hello,
Im trying to run a rather heavy calculation on our server, and high levels of multithreading causes the system to crash, sadly without crash log. The system does not respond to anything, both over the network and pressing the power button, and requires the power connection to be pulled before it can restart.
The linux version is "Ubunto 24.04.2 LTS", with two AMD EPYC 7763 64-Core Processor CPUs, about 1 TB of ram, a GeForce RTX 3050 8GB graphics card and a Supermicro H12DSi-NT6 mainboard.
When I use parpool and maxNumCompThreads at 16, the system works fine, but rather slow. At 32, the system works fine for a couple of minutes, before crashing, even when the CPU and Ram load never goes above 20%.
The computations include ffts, interpolation and complex to real and vice versa conversions.
Do you have any tips or hints where I can check what is happening, or do you have any information what is going on and what I can do to resolve this problem?
ThanksHello,
