The SNIC Science Cloud (SSC)  invites all interested current and future users to a training workshop on an introductory level at Mid Sweden University, Campus Sundsvall, 10:00-16:00 on the 31^st of August.

We will introduce cloud computing in general, including covering the best practices around security and you will learn the basics of how to work with the OpenStack based Infrastructure-as-a-Service (IaaS).

The majority of the time will be spent in lab sessions on basic usage of the IaaS cloud.

We will have a downtime of all our systems Monday, 2018-08-13, 18:00 - Tuesday, 2018-08-14, 10:00.

The reason for this is that there will be a power outage on the entire Umeå Campus, Monday, 2018-08-13, 20:00-24:00. We need some time after this to get all our systems at HPC2N up and running again.

Because of an automatic kernel update on the Skylake and Volta GPU nodes, they failed to reboot afterwards. They need a manually built kernel and we are working on the problem.

Update 2018-07-03 14:00: New kernels built and the Skylake and Volta nodes are up again.

Introduction to HPC2N's systems with a focus on the Kebnekaise cluster

In this course we begin with a short introduction to Linux, which is what is used on HPC2N's compute clusters. This part is only meant for complete beginners to the Linux operating system, and can be omitted if you are proficient already.

The recently announced expansion to Kebnekaise is now available to users.

Please read the Kebnekaise usage guide for information on how to use the various parts.

The upgrade of Lustre parallel file system (/pfs/nobackup) as well as the rest of the maintenance we have done during the week are now complete. All systems are up and running again, including the batch queues on both Kebnekaise and Abisko. The login nodes are open for acess again.

During the week we have, among other things:

Kebnekaise Expansion: A Welcome Addition for all Users

We are currently installing and verifying the expansion of Kebnekaise that we announced at the HPC2N Open House last fall. The expansion is a welcome addition to a heavily loaded Kebnekaise and will improve queueing times, particularly for GPU jobs. The expansion consists of a combination of standard Intel Xeon Gold 6132 (Skylake) CPU nodes and nodes also equipped with NVIDIA V100 Volta GPUs. This makes HPC2N one of the first accademic HPC sites in Europe to have the V100 GPUs in production.

We have a major maintenance to upgrade the Lustre parallel file system (/pfs/nobackup).

One of the goals is to introduce new functionality, for instance project based storage.

We will also do a number of related changes and optimizations to the Lustre file system setup.

We are planning for a full week of complete downtime on all HPC2N systems, including login and thinlinc nodes, starting 2018-06-04 07:30 CEST.

Please make sure to copy any files you want to work with during the downtime to some other system well in advance of the maintenance.

SNIC joins iRODS Consortium

SNIC now implementing new iRODS-based infrastructure
