The tests were carried out using two modes: Intel and GCC compiled MPI API and libraries. In order to study the scalability of the software two approaches were considered: + 1. A core-based performance analysis where 1 MPI task per core, 16 cores per socket, that is 16 MPI tasks per socket, and 1 extra core per compute node to handle communications when multiple compute nodes were used. For the runs on a single node (that is with the number of cores varying between 1 and 32) no extra core was considered. 2. A node-based performance analysis where 1 MPI task per core, and all cores in the socket, that is 24 MPI tasks per socket, including an extra core for MPI communications when multiple nodes are used. For runs on a single node there is no need to use an extra core for communications. @@ -40,7 +41,7 @@ git clone http://gitlab.mpcdf.mpg.de/vrs/gadget4 ##### In this UEABS repository you can find: -- The cloned version used in the benchmarks (version of June 22, 2021):[gadget4-benchmarks.tar.gz](./gadget/4.0/gadget4-benchmarks.tar.gz) +- The cloned version used in the benchmarks (version of June 22, 2021): [gadget4-benchmarks.tar.gz](./gadget/gadget4-benchmarks.tar.gz) This tarball includes the `src` code, `examples`, `buildsystem`, and `documentation` folders.
