Dear Community,
When running a simulation with weight windows in OpenMC version 0.14, the simulation freezes after a certain number of batches. Changing the seed also changes the batch where the simulation stops.
The same simulation runs fine in version 0.13.
Any suggestions? Thanks in advance!
I have met the same issue. I have 22 threads. The simulation froze in a certain batch and only one CPU ran at that time. In 0.13 I also met this issue in some of my models containing wws. No idea what’s the cause.
Maybe particles at one thread split a lot but particles on other threads have already reached the end of life, so finally only one thread is running which seems stuck?
Is it possible to redistribute split particles to other threads?
Installing from source solves my issue. This probably relates to this bug which has been fixed in develop branch.
Thanks for your answers Kingyue. Unfortunately, even after installing the very latest version of the code, the problem still exists. I experienced the same situation as you: out of 48 cores used to run the simulation, only 2 were actually working when the simulation froze. I’ll let you know what I find out.
