CITA has 3 high-performance computer clusters. Your code's CPU, memory, OS, and architecture requirements will guide your choice of which platform to use.
The 4 dolphins have 4 CPUs apiece and are a great choice for serial, OpenMP or MPI jobs which require no more than 4GB of memory. Octopus is also available for smaller shared-memory jobs ( 4 CPUs & 28GB). Large shared-memory jobs (up to 64GB) are well-suited to orca but you need to email requests to book time (typically allotted in 1 week chunks). The largest amount of distributed memory is found on the lobster cluster while the McKenzie cluster has a huge number of CPUs.
