Many HPC systems check the state of a node b efore  running a n  application, but not very many check that the performance of the node is acceptable before running the job.

Get better  performance from your nodes  by binding processes and  associating memory to specific cores .

Parallel programming is not easy, but one tool you can use to help parallelize your application is OpenMP. Most compilers are compatible with OpenMP and allow you to parallelize your code on a single node.

The Julia language is a very powerful parallel computing model that works across multiple cores and cluster nodes.

Effectively monitoring your cluster can be one of the keys to understanding how the hardware and software are interacting. In many cases, this means examining the performance of a single node.
