E3SM Dedicated Machine - Anvil

E3SM’s Anvil computer is a 240 nodes cluster dedicated 24/7 to the E3SM project.

In 2016, the Department of Energy (DOE) Office of Biological and Environmental Research (BER) purchased a first E3SM dedicated system, “Anvil”, to support E3SM model development work. This purchase was critical for the development of the E3SM v1 model, and in 2017 it was doubled in size.


Anvil is a 240-node cluster, containing a dual-socket Intel Xeon Broadwell CPUs with 64 GB of DDR4 DRAM and 36 cores per node.  It uses an FDR InfiniBand network and has 500TB of disk storage.  Anvil is hosted by Argonne National Laboratory’s Computing Resource Center.



Anvil nodes are open to all developers working on tasks funded by the E3SM project.  Anvil is currently not open to work on the E3SM model funded by other projects such as SciDAC and CMDV.
