@@ -137,6 +137,43 @@ Gadget-4 uses one core per compute node to handle communications. Hence, when al
nodes we must take into account an extra core. So, if we want to run the code with 16 mpi tasks/socket we
must allocate 33 cores per compute node. For a run with 1024 cores in 32 nodes we allocate 1056 cores.
##### OUTPUT of a run with 1024 cores
```
Running on hosts: jwc03n[082-097,169-184]
Running on 32 nodes.
Running on 1056 processors.
Current working directory is /p/project/prpb84/Test-Case-A/00512_cores
Shared memory islands host a minimum of 33 and a maximum of 33 MPI ranks.
We shall use 32 MPI ranks in total for assisting one-sided communication (1 per shared memory node).
