Cruncher

Cruncher is the INTERTIA Lab’s compute server in the datacenter at the Drexel College of Computing and Informatics. We use it for a lot of our recommendation runs.

Specs

CPU

2x AMD EPYC 7662 (64 cores, 128 threads, 2GHz)

Memory

256 GiB

GPU

NVidia A40 (48GB)

Storage

SSD (home directory + software), network-attached redundant spinning disks (experiment data)

Operating system

Ubuntu 24.04

Idle power draw

220 watts

Power Measurement

Chassis power is measured by the input power reported by the PSUs to the ASUS ASMB10-iKVM. We collect power readings from the iKVM over the Redfish interface and record them in Prometheus.

CPU power is reported by RAPL through Linux powercap, and GPU power is reported by the NVidia Datacenter GPU Monitor.

Note

This is a shared machine, so power consumption records are not always well-isolated from other workloads.
