HIGH PERFORMANCE COMPUTING CLUSTER
HPC Cluster is a group of computing nodes joins computational powers of them to provide a more combined computational power. Therefore, cluster computing utilizes multiple machines to provide a more powerful computing environment perhaps through a single operating system. In its simplest structure, as said above the HPC clusters are intended to utilize parallel computing to apply more processor force for the solving the problem. Though from the outside the cluster may look like a single system, the internal workings to make this happen can be quite complex. The idea is that the individual tasks that make up a parallel application should run equally well on whatever node they are dispatched on. However, some nodes in a cluster often have some physical and logical differences. High-Performance cluster at Central computer center has a 14 node architecture; One master node, 6 GPU Compute node, 6 compute nodes, 1 Xeon Phi (KNL) node.
