Open position: Technical system administrator

UPPMAX has received instructions to start procuring a system to meet Uppsala University's local needs for sensitive and non-sensitive HPC and cloud services in both research and general education. Funding is supplied by the disciplinary domains and from the Vice-Chancellor.

Any research group with an interest is welcome to contact the Director (director@uppmax.uu.se) and/or UPPMAX support (support@uppmax.uu.se) to discuss collaboration or co-investment.

Read on for some more details.

After many years of service, the time is approaching when Rackham will be too old to keep running. Rackham will be shut down on 2024-12-31. Before we say anything else, we want to express a deep appreciation for each of our users — it is you that made this system so meaningful and pushed us to the limit in so many ways.

This is why we have made plans for your future, and why the UPPMAX staff are contacting you now. Please continue reading to learn about what will happen to your compute and storage projects and how we plan to help you transition to a new system.

The Ångström Laboratory houses the UPPMAX compute hall, and the property manager, Akademiska Hus, will be performing work on the cooling system as part of an energy-saving project called “Project Bläckfisken.” 

To facilitate this process, Akademiska Hus kindly requests a 48-hour power-down period for the compute hall between October 4 and 5. During this time, all systems will be unavailable.

We apologize for any inconvenience this may cause and appreciate your understanding as we aim to inform you well in advance.

On Tuesday (2023-05-16) at 13:00 we will celebrate 20 years with UPPMAX. You are welcome to drop by on the ground floor of Ångström building 10! There will be some coffee and cake.

This year, UPPMAX celebrates 20 years of providing high-performance compute and storage services to the Swedish research community. During the past two decades, UPPMAX has witnessed a remarkable development in technical platforms, hardware, and the scientific landscape.

The SNIC board has approved about 10 MSEK in funding to procure more hardware for Bianca, including more GPU nodes, more storage, and more semi-fat compute nodes. With this increase in capacity and lifetime, we will be able to serve our growing community for several more years.

Additionally, an investment by the Kamerlin group has resulted in 144 nodes from the old NGI cluster, Irma, now added to Rackham. These resources, with 16 cores and 256 GB of RAM per node, amounting to about 1.5 million core-hours per month, are already available in the "core" partition (though the Kamerlin group naturally has priority over others). Look for nodes named "r1000" and higher!

During the coming year, Bianca will get four really high-mem nodes, 48 cores each with 768GB RAM. We will also augment the number of 256GB nodes considerably, at least 50 more of those, for a total of more than 260 nodes compared to 204 today. This will also mean that we can give more memory (and possibly cores) to each login node.

UPPMAX has laid an order for 3.75 PB of effective storage that will be added to the Crex storage system in the Spring of next year. This will bring the total volume of storage available on Rackham and Snowy to about 9.75 TB. Part of this space is reserved for system software and central databases, and available quota for projects is expected to increase by over 50%. This should be sufficient until the planned end-of-life of Rackham and Crex at the end of 2024. 

Until the extension is in place, space on Crex is very tight. Please continue to delete unnecessary files, be patient with performance degradations, and please wait until Spring before generating significant amounts of new data.

The SNIC Board has approved funding that will let UPPMAX not only continue to run Rackham and Bianca through the end of 2024, but also make some necessary investments to improve the user experience. Details are still being hammered out, but these investments will take place in early 2022, and will ensure that the user community can continue to grow and evolve. 

UPPMAX is happy to announce that Bianca now offers GPUs! The GPUs that were provided by SNIC are available for all users. GPUs are a type of accelerator that may significantly increase performance for certain workloads, for instance, workloads that contain large amounts of identical operations on independent pieces of data.

Today, the 20 millionth job on Rackham was submitted.

Ny Teknik har intervjuat en av våra anställda i en artikel om effekterna av metoo-uppropet. För drygt tre år sedan synliggjorde metoo-uppropet #teknisktfel sexuella trakasserier inom teknikbranschen. Sedan dess har framsteg gjorts menar initiativtagarna. Men mycket återstår att förbättra på arbetsplatserna.

The Swedish Research Council is conducting a survey regarding current practises and available support functions for research data management. This work is part of a commissioned project to coordinate activities about Open Access data.

Answer the survey here: https://survey.vr.se/Survey/601

An estimated 40% of all publications reported to SciLifeLab under 2020 involved work done on UPPMAX resources. 

UPPMAX is gathering interest in user-funded GPU resources on Bianca. Users are invited to contact us.

The EuroCC National Competence Center Sweden (ENCCS) is an initiative to establish a support organisation for HPC competence in general and especially in large-scale applications running on EuroHPC systems (such as LUMI).

A new resource for Artificial Intelligence and Machine Learning AI/ML research has recently opened at C3SE, the national centre for scientific and technical computing at Chalmers.

Several large European HPC-sites are reporting issues with cybersecurity and several SNIC centres have recently restricted access to some of its services.

While the main function of UPPMAX is to provide a world-class digital research environment, as a tax-funded resource we can and should keep public welfare in mind. In the current crisis, HPC resources can play a crucial role in contributing to the understanding of the virus itself as well as mitigation strategies and their impact. 

The UPPMAX board has decided to offer users an opportunity to
co-finance a pool of Nvidia Tesla T4 cards with 16 GB RAM each, at a price of
roughly 20 000 SEK/card. Read on if your research group may be interested in buying access to GPU capability at UPPMAX.

The 6PB large storage system, called Crex, is nearly fully allocated. This is the storage system attached to Rackham and Snowy. When we have allocated all the space available on it, we cannot both grant new projects that need disk space and prolong old ones with large allocations. Please read on to learn more about the situation.

Since this spring, we have been offering the Lutra offload storage system suitable for "cold" data which is not accessed or changed frequently, but which still has to be kept available on our clusters.

Due to the popularity of this service, the UPPMAX board wants to offer current
PIs at UPPMAX the possibility to sign up for additional storage. This time,
it will also be possible to buy storage suitable for sensitive personal data.

Seminar by Philipp Schlatter, the chair of the SNIC Allocations Committee (SNAC), "SNIC and SNAC: Handling of large-scale computer time allocations in Sweden", to be held on in the afternoon on September 25th.

As of now, CONDA should work (module load conda) again, but please report anything weird (For CONDA, being slow is not weird).

Due to some changes and external alterations, the entire CONDA installation is in need of being re-installed. This might cause some lag and even some failures in the near future. Hopefully we will have the systems and repositories up and running as soon as possible.

A EuroHPC Joint Undertaking, involving Finland, Belgium, Czech Republic, Denmark, Norway, Poland, Sweden and Switzerland, will be placing a large HPC system at CSC in Finland. Scientists in member countries will be able to use the machine starting Q4 2020.

A research group used UPPMAX resources in a recent publication that has caused some popular interest. Around 4500 BCE, megalithic funerary monuments began to be built in northwestern Europe. The group's genomic investigation, published in the Proceedings of the National Academy of Sciences (PNAS), provides insight into the people associated with this long-standing megalith funerary tradition, including their social dynamics.
