Bianca users: report interest in GPUs on Bianca
UPPMAX is gathering interest in user-funded GPU resources on Bianca. Users are invited to contact us.
Since this spring, a number of Nvidia Tesla T4 GPUs are available in our
older Snowy cluster. These were paid for by individual groups for education
and research. Those groups have priority access. However, anyone using Snowy
can submit jobs to them, and those will be scheduled when no priority jobs
are present in the queue.
Currently, we are also exploring the need and interest for GPUs in the
Bianca resource for sensitive data, in a similar fashion as the GPUs in Snowy. If you have an interest in this and would want to cofund (part of a) GPU node for priority access to that node once it's installed, pleaseget in touch with our technical coordinator Carl Nettelblad,
More details on using the GPU nodes on Snowy are available at:
Starting in 2021, UU undergraduate courses will also be able to use Snowy GPUs for
machine learning and other uses where they are relevant. The total pool for
GPUs will be expanded to accomodate this. A limited GPU capability will
also be present in the Uppsala site for the SNIC Science Cloud, "Dis".
For general-purpose (non-sensitive) machine learning research, a high number
of modern GPUs are now also offered by SNIC in form of the Alvis resource
at Chalmers, https://www.c3se.chalmers.se/about/Alvis/.
For updates and information on current system status, please see the System Status page.
Bigger Bianca login nodesIncreasing resources of the Bianca login nodes has been much requested by ourSNIC-SENS users. We are thrilled to announce that we are bumping the specs forall Bianca login nodes and extending total number of compute nodes with anadditional 72x256GByte ("fat") nodes.
Undergraduate courses at UPPMAX
Uppsala University courses can request UPPMAX resources to use in teaching. Don't forget to apply soon for courses starting in Period 3.
Bianca and Rackham news
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!

Lovande molekyl mot coronavirus på Uppmax
Uppsalaforskare har lyckats ta fram en molekyl som hämmar förökning av coronavirus och har stor potential att utvecklas till läkemedel mot covid-19. En del av arbetet utfördes på UPPMAX system.
Bianca to be upgraded in 2022
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.
More Rackham storage in Spring 2022
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.
Online training workshop: "Awk Workshop", Uppsala, January 17 (+18)*, 2022
This 1+1 days workshop aims to promote the awk tool for use in everyday research work and urges you to find solutions yourself rather than expecting ready-made ones. Thus, the material given during the seminar will not be a complete guide or manual. The purpose of the workshop is to give an overview of the capabilities of the awk language and to underline some of its particular strengths as well as its disadvantages.
When: January 17(+18)*, 2022
* During the workshop, you will be able to register for the second day of the workshop.

Life of Rackham and Bianca extended through 2024
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.
VR invites comments on the future of HPC in Sweden
In June this year, the Swedish Research Council (SRC) decided to call off the process for renewed funding of the Swedish Infrastructure for Computing (SNIC). The process has begun to
find another form for a national research infrastructure and SRC wants
to hear from you about your compute and storage needs.
We ask all our users to leave feedback at the following link:
It is important that SRC gets input from all its users, so please take
this opportunity to make your needs heard.
GPUs now available in Bianca
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.

Several positions open
User-paid GPU pool available
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.
Rackham storage nearly full
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.
User-paid offload storage available at UPPMAX
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.
