GPU Cluster Power9 (Outdated)

Warning

This page is deprecated! The system Power9 is decommissoned since April 2025!

Overview

The multi-GPU cluster Power9 was installed in 2018. Until the end of 2023, it was available as partition power within the now decommissioned Taurus system. With the decommission of Taurus, Power9 has been re-engineered and is now a homogeneous, standalone cluster with own Slurm batch system and own login nodes.

Hardware Resources

Component	Count
Number of nodes	32
GPUs per node	6 x NVIDIA V100-SXM2 GPUs (32 GB HBM2)
CPUs per node	2 x IBM Power9 CPU (2.80 GHz, 3.10 GHz boost, 22 cores)
RAM per node	256 GB RAM (8 x 16 GB DDR4-2666 MT/s per socket)
NVLink bandwidth	150 GB/s between GPUs and host

We provide additional architectural information in the following. The compute nodes of the cluster Power9 are built on the base of Power9 architecture from IBM. The system was created for AI challenges, analytics and working with data-intensive workloads and accelerated databases.

The main feature of the nodes is the ability to work with the NVIDIA Tesla V100 GPU with NV-Link support that allows a total bandwidth with up to 300 GB/s. Each node on the cluster Power9 has six Tesla V100 GPUs.

Note

The cluster Power9 is based on the PPC64 architecture, which means that the software built for x86_64 will not work on this cluster.
