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). + + ___ __ ____ ___ ____ ____ __ + / __) /__\ ( _ \ / __)( ___)(_ _)___ /. | +( (_-. /(__)\ )(_) )( (_-. )__) )( (___)(_ _) + \___/(__)(__)(____/ \___/(____) (__) (_) + +This is Gadget, version 4.0. +Git commit 8ee7f358cf43a37955018f64404db191798a32a3, Tue Jun 15 15:10:36 2021 +0200 + +Code was compiled with the following compiler and flags: +... + +Code was compiled with the following settings: + COOLING + DOUBLEPRECISION=1 + GADGET2_HEADER + MULTIPOLE_ORDER=3 + NSOFTCLASSES=2 + NTYPES=6 + POSITIONS_IN_64BIT + SELFGRAVITY + STARFORMATION + TREE_NUM_BEFORE_NODESPLIT=4 + + +Running on 1024 MPI tasks. +``` ### UEABS Benchmarks -- GitLab
