Using mprime
I only use option 15 16 (Options/Torture Test) since we just need mprime for stress testing. It will max the detected threads across all CPU's, I just hit 'enter' when it asks 'Number of torture test threads to run (x):'.

## Assuming you're not already in the mprime directory you created if you're doing this all in one go from this article
cd mprime
./mprime
## If this is your first time extracting/using, it will ask if you want to join GIMPS- I usually hit 'n' since this is for troubleshooting only anyways
[root@c103454 mprime]# ./mprime

Your choice:
Number of torture test threads to run (80):
Choose a type of torture test to run.
1 = Smallest FFTs (tests L1/L2 caches, high power/heat/CPU stress).
2 = Small FFTs (tests L1/L2/L3 caches, maximum power/heat/CPU stress).
3 = Large FFTs (stresses memory controller and RAM).
4 = Blend (tests all of the above).
Blend is the default. NOTE: if you fail the blend test but pass the
smaller FFT tests then your problem is likely bad memory or bad memory
controller.
Type of torture test to run (4):
|
Usually run test (2) for CPU only, (3) for Memory only, and blend Blend (4) to perform both.
