Number of hardware threads detected (8) does not match the number reported by OpenMP (1).
Consider setting the launch configuration manually!
Reading file /home/diego-m/hd42/fluorosceina/box_building/solvent_test/solvent_test.tpr, VERSION 5.0.2 (single precision)
Using 8 MPI processes
Using 1 OpenMP thread per MPI process

Non-default thread affinity set probably by the OpenMP library,
disabling internal thread affinity
