 SomeoneSerge (UTC+U[-12,12]) | Context: error: cycle detected in build of '/nix/store/391cjl6zqqsaz33disfcn3nzv87bygc1-slurm-23.11.1.1.drv' in the references of output 'bin' from output 'lib' | 15:34:41 |
| SomeoneSerge (UTC+U[-12,12]) | Just as mpich and openmpi aren't amenable to splitting their outputs (can't just link the library but must keep the executables in the runtime closure for no good reason), neither is slurm apparently | 15:35:29 |

 markuskowa | SomeoneSerge (hash-versioned python modules when): I have managed to split the dev outputs of the mpi implementations. I will open a PR soon. | 09:34:16 |
| SomeoneSerge (UTC+U[-12,12]) | WOW! What did you do to the config.h? | 10:15:59 |
| SomeoneSerge (UTC+U[-12,12]) | I managed to make slurm build libpmi2.so and to split it out into a separate output last night | 10:16:18 |

Linking slurm's libpmi2 seems to kind of work at aalto:

| SomeoneSerge (UTC+U[-12,12]) | (still a ton of memory leaks reported by asan though) | 23:50:53 |
| SomeoneSerge (UTC+U[-12,12]) | (idk, maybe leaks are a feature of mpi and I should ignore this) | 23:51:23 |
