LOTUS cluster specification
Details of the current LOTUS cluster
LOTUS is a cluster of over 260 nodes/hosts and over 53,000 CPU cores. A node/host is an individual computer in the cluster with more than 1 processor. Each node/host belongs to a specific host group. The exact number of cores available varies as occasionally nodes/hosts are taken out of the cluster for special purposes. The number of processors (CPUs or cores) per host is listed in Table 1 with the corresponding processor model and the size of the physical memory RAM available per node/host.
