[OMPI users] catching SIGTERM in Open MPI 5.x

Hello, I am trying to implement some graceful application shutdown in case mpirun receives a SIGTERM. With Open MPI 4.x, this works just fine, and SIGTERM is forwarded. With Open MPI 5.x I now struggle as prte seems not to forward SIGTERM by default. If I try to include this in the list of SIGN

here. Best way to solve this is to update your application to the new mpif08 module. I know this may end up in a lot of work and finding bugs along the way. ;) Best regards Christoph Niethammer - Original Message - From: "Open MPI Users" To: "Open MPI Users" C

Re: [OMPI users] OMPI 4.0.4 how to use mpirun properly in numa architecture

Hello Carlo, If you execute multiple mpirun commands they will not know about each others resource bindings. E.g. if you bind to cores each mpirun will start with the same core to assign with again. This results then in over subscription of the cores, which slows down your programs - as you did
