Reply To: Choose between CPU and GPU

[sfraniatte]

Ok, I have two computers :
_ an Ubuntu 22.04 VM on windows 11 with 6 CPU cores (Intel(R) Core(TM) i5-10400T CPU @ 2.00GHz)
_ an Ubuntu 24.04 with 32 CPU cores (AMD Ryzen Threadripper PRO 5975WX 32-Cores) and with a GPU card

My goal, today, is to launch a calculation on the computer which run on Ubuntu 24.04 on the CPU cores to run a biger simulation. However, when I test with the same case (my own case), the calculation is slower than when it is done whith the VM on windows.

I am wondering if the problem comes from CPUs which does not have the same brand.
