UCI’s Earth System Modeling Facility (ESMF) offers accounts to all UCI researchers and students interested in High Performance Computing. The ESMF presently consists of a cluster of 88 IBM Power4 CPUs in seven 8-way and one 32-way SMP nodes running AIX 5.1L. The Visual Age compilers fully support OpenMP and MPI. The computational environment is batch-oriented and is suitable for large- scale numerical simulations. The environment is similar to that found at many national supercomputer centers, but, we hope, with less bureaucracy. Instructions for obtaining an ESMF account are at

Idle ESMF CPU time is a waste and the goal is to minimize it. We have constructed a batch queue environment which gives priority to the earth-systems simulations which are its primary task, and places other jobs in queues of lower priority (standby queues). This allows other UCI researchers to benefit from idle CPU time without penalizing ESMF’s core users.
