Respublica - High Performance Computing (HPC)

HPC is a general term for a large computing system. In our case, the HPC consists of many servers which are tied together with software and hardware such that we can compute large batches of work and/or compute a large amount of work in parallel.

Batch computing
Execute a series of computational jobs. The computing system will schedule them to run somewhere among its many servers if it has free resources.

Parallel computing
A single software piece will orchestrate computational work among multiple available resources which are not strictly confined to an individual server.

Respublica is a shared Linux command line based environment in which you submit computational jobs to a large pool of resources where they will be scheduled run. All the servers of Respublica are connected with very fast specialized networking. Additionally, there is a large NAS system for data storage attached to Respublica via networking.
