256 GiB RAM (~2GB/core), no swap

480 GB SSD local disk

dodrio/cpu_rome_512: large-memory partition:

42 workernodes, each with:

2x 64-core AMD Epyc 7H12 CPU 2.6 GHz (128 cores per node)

512 GiB RAM (~4GB/core), no swap

480 GB SSD local disk

dodrio/cpu_milan: phase 2 main partition:

384 workernodes, each with:

2x 64-core AMD Epyc 7763 CPU 2.45 GHz (“Milan” microarchitecture, 128 cores per node)

256 GiB RAM (~2GB/core), no swap

480 GB SSD local disk
