How much memory does it take to run the large benchmarks?
For the Large data set, the intention is that each benchmark in the suite be runnable with 2GB of memory per rank. If you run one rank per processor core, which is the usual case, this implies 2GB of memory per enabled core on the system. A minimum of 64 ranks are required for the benchmarks to work, which implies a minimum memory requirement of 128GB, although higher may be required on your system. On a cluster running only a few ranks per node, the 2GB per rank may not be sufficient because of other demands on memory from the OS or libraries, or the way the arrangement of the process images is fragmented in memory. See the system-requirements.html document for a detailed list of individual resource requirements.
