Integration of Leonhard Open into Euler
The Leonhard Cluster was introduced in 2017 as a new platform for big data analytics featuring petabytes of high-performance storage and GPU nodes for machine learning applications to process large amounts of data. At this time, the Euler cluster did not have any GPU nodes available and could not cover this new use-cases that caught the attention of more and more researchers. Over the years, we also introduced GPU nodes on Euler and increased the capacity of the high-performance storage, such that both systems have become very similar. From an operational point of view it makes a lot of sense to integrate the Leonhard Open cluster into Euler as this allows us to exploit synergies in the system management, software installation and support.
The Leonhard Open shares will be transferred to Euler. This migration happens in a transparent way and apart from the hostname (euler.ethz.ch instead of login.leonhard.ethz.ch) nothing will change for the users. Both software stacks feature the same toolchains (GCC 4.8.5, 6.3.0, 8.2.0 and Intel 18.0.1). We already started to install packages on Euler that were before only available on Leonhard Open to make the migration of the workflows as seamless as possible. Still there will be some installations missing and we will be happy to assist you in porting your workflows from Leonhard Open to Euler.
