[Mesa-users] Technical issue: calculations going incredibly slow

[Amedeo Romagnolo]

Hi all,

here is my problem. I have set a pretty vanilla simulation on MESA (inlists
attached), but because of some weird black magic my calculations go fast
enough over the first ten minutes, and then they dramatically slow down.
And I'm not talking about timesteps, but about the actual calculation time
for each timestep.

Even more weirdly, if I reset my PC and restart the simulations (./re) the
code goes fast for another ~10 minutes and then slows again.

I'm using Ubuntu 20.04, and I made sure no other process was running at the
same time. And yes: I set the right number of cores.

Did this happen to anyone else? Do you have any idea on how to solve this?

Cheers,

Amedeo
