Gromacs is a molecular dynamics package primarily designed for biomolecular systems such as proteins and lipids.
Benchmarking
2011 Hardware
Benchmark data for running Gromacs on Cheaha will be developed leveraging the benchmark foundation of the NIH's Biowulf cluster Gromacs testing suite combined with local work flow characteristics.
2007 Hardware and Gromacs 3.x
Note: The Gromacs 3.x code base was severely limited in spanning multiple compute nodes. The limit for 1GigE network fabrics was 4 nodes. The following performance data is provided for historical reference only and does not reflect performance of the Gromacs 4.x code base currently install on Cheaha.
Two identical 4 CPU Gromacs runs and the jobs spread out as follows based on current queue load (the new nodes are using Infiniband, the old TCP for message passing):
