Hardware and Technical Specs
Minerva cluster design is driven by the research demand performed by Minerva users (i.e. the number of nodes, the amount of memory per node, and the amount of disk space for storage).
The following diagram shows the overall Minerva configuration.
- 4 login nodes – Intel Xeon(R) Platinum 8168 24C, 2.7GHz – 384 GB memory
- 275 compute nodes* – Intel 8168 24C, 2.7GHz – 192 GB memory
- 13,152 cores (48 per node (2 sockets/node))
- 37 high memory nodes – Intel 8168/8268 24C, 2.7GHz/2.9GHZ – 1.5 TB memory
- 48 V100 GPUs in 12 nodes – Intel 6142 16C, 2.6GHz – 384 GB memory – 4x V100-16 GB GPU
- 32 A100 GPUs in 8 nodes – Intel 8268 24C, 2.9GHz – 384 GB memory – 4x A100-40 GB GPU
- 1.92TB SSD (1.8 TB usable) per node
- 10 gateway nodes
- New NFS storage (for users home directories) – 192 TB raw / 160 TB usable RAID6
- Mellanox EDR InfiniBand fat tree fabric (100Gb/s)
*Compute Node —where you run your applications. Users do not have direct access to these machines. Access is managed through the LSF job scheduler.

Purchased by private groups and hosted on Minerva.
Total system memory (computes + GPU + high mem) = 210 TB
Total number of cores (computes + GPU + high mem) = 22,164 cores
Peak performance (computes + GPU + high mem, CPU only) = 2 PFLOPS
File System Storage
For Minerva, we focused on parallel file systems because NFS and other file systems simply cannot scale to the number of nodes or provide performance for the sheer number of files that the genomics workload entails. Specifically, Minerva is using IBM’s General Parallel File System (GPFS) because it has advantages that are specifically useful for this workload such as parallel metadata, tiered storage, and sub-block allocation. Metadata is the information about the data in the file system. The flash storage is utilized to hold the metadata and tiny files for fast access.
Currently we have one parallel file system on Minerva, Arion, which users can access at /sc/arion. The Hydra file system was retired at the end of 2020.
