Andes is a (704)-node commodity-type Linux® cluster. Andes provides a conduit for large-scale scientific discovery via pre- and post-processing of simulation data generated on Summit. Each of Andes’s 704 nodes contain two 16-core 3.0 GHz AMD EPYC processors and 256GB of main memory. Andes also has nine large memory GPU nodes. These nodes each have 1TB of main memory and two NVIDIA K80 GPUs with two 14-core 2.30 GHz Intel Xeon processors with HT Technology. Andes is connected to the OLCF’s high performance GPFS® filesystem, Alpine.
