Does anybody know how can I tuning bigmem and hugepages settings for cluster node. On this node is running mostly one process which consuming allmost 98% of memory and 100% CPU. On the internet I have found only tuning settings for Oracle. Does anybody knows how can I tuning linux kernel for machine with 16cores and 24GB or 48Gb RAM ? I dont need TCP settings, for me important is memory and CPU. Very often software on the cluster using OpenMPI. Does anybody has an experience with tunning MPI environment ? greetz Konrad
