The Darwin Cluster
Los Alamos National Lab. (LANL), Los Alamos, NM (United States), Charles Garrett, USDOE · 2018
Darwin is an ASC funded test bed cluster that also allows external users to use the idle resources within. Darwin is configured as a non-standard HPC production stack, and as such, has some interesting quirks to it. Darwin is a very heterogeneous cluster. Where average clusters are designed as homogeneous to make management and expectations simple, Darwin was designed as a test bed with many types of nodes available for running. With this heterogeneity comes its own run time experience. We provide nodes that contain x86 architectures of many flavors and also Power PC and ARM architectures. We have nodes with terabytes of memory and nodes with all kinds of GPUs.
