CosmoMC: gfortran memory problem
Posted: April 16 2020
I'm having trouble with some kind of memory leak running CosmoMC compiled with gfortran. I tried downloading the updated CAMB/CosmoMC files from GitHub, which I saw mentioned a gfortran memory issue fix, but I still have the same problem.
The sympton is that the memory usage by the mpi processes continuously increases when I run an action=0 chain, until eventually the system kills the job. I am running with gfortran 7.5.
I ran the python test script in the camb/camb/tests folder and it didn't come back with any message or confirmation of the memory leak issue. So maybe my issue is unrelated.
I don't know what actually caused this to start occurring, my jobs with the exact same options were running fine earlier (few weeks ago), and as far as I can tell there haven't been any updates to the computer's compilers etc. on the timescale when I started seeing this problem. Thanks for any help.
