Scheduled Marvin Downtime on March 26, 2024

Dear HPC users,

due to a firmware upgrade we need to schedule a Marvin downtime for Tuesday, March 26, 2024. It will start at 9:00 and most likely take around four hours.

No job that is currently running should be affected. Any jobs that are in the waiting queue on that day will simply start running after the maintenance window.

We will notify you when the maintenance work has been completed.

Marvin registrations now open!

Dear HPC users,

we are happy to announce that you can now register for using Marvin. Below are the most important things you need to know:

HPC-Cluster "Marvin" Opening on March 11, 2024

Testing phase for experienced users will be re-launched on February 13th

"Marvin", Uni Bonn's supercomputer, installed in 2023, is nearing its final release day. The cluster, consisting of 192 MPP nodes with a total of 18400 compute cores plus an additional 300 NVIDIA GPUs, had been presented to the public in a festive inauguration ceremony on October 20th, marking the start of an intense testing phase allowing highly experienced "power-users" to already use the cluster for numerical simulations while at the same time reporting any potential problems or hickups to the maintenance team at the Computing Centre. This first testing phase started overwhelmingly positively, showing that the performance of the cluster is even higher than had been previously promised by the vendor Megware.

Marvin opening delayed to late February

We regret that we have to postpone the opening of Marvin to everyone. It will be delayed to at least the end of February. The closed testing phase will most likely resume before that date.

This delay is due to necessary additional work on the cooling infrastructure and monitoring hardware.

As always, we will keep you up to date via at least our two main communications channels: our website https://www.hpc.uni-bonn.de and the hpca-forum@listen.uni-bonn.de mailing list.


Best regards

Your HPC Team

New course: Advanced Machine Learning - registration open!

Dear HPC users,

the HPC/A Lab presents our new training course "Advanced Machine Learning". It continues where the Foundations of Machine Learning Course stopped. We will cover second-order optimization, derivative evaluation, generative learning, reinforcement learning and more.

This one-week course will take place in the week of March 11-15, 2024. For more information on the course topics, prerequisites and to register, visit the course page on eCampus:

https://ecampus.uni-bonn.de/goto_ecampus_crs_3255322.html

We are looking forward to seeing you during the course.

Your Lecturers, Elena and Moritz

Cleanup of old Bender data

To free up disk space on Bender, we will soon delete orphaned user data. Initially this will only be data from users who do not exist at the university anymore.

If you know of data from a former colleague that you might require, please contact us.

If you yourself are not using Bender anymore, please consider deleting your old data or notifying us about what else can be deleted.

We will not delete any data before February 15.

Marvin - start of operations delayed to January

We now expect that Marvin will be available to everyone in the second half of January 2024.

Marvin - the next steps

Construction measures completed successfully and on time, inauguration in October, open for use in December
