mixing them up… IDTOKENS for daemons, others for jobs, issued from OAuth vs Vault vs self signed vs ...
With the ever changing IT and political landscapes also the HTC clusters at DESY are evolving with these changes. We will give an overview and status, what over the past year is new and where we plan to go with our compute clusters. Efficient utilization of resources has become even more pressing following recent geopolitical turmoil and with climate change becoming even more pressing, for...
In this communication, we are going to present the multiple HTCondor instances that have been deployed at GRIF for several years. GRIF is a distributed Tier-2 WLCG/EGI site made of four (4) different subsites (IJCLab, IRFU, LLR, LPNHE), in different locations of the Paris region. The worst network latency between the subsites is within 2-4 msec with three (3) of them connected with a...
The computing resource needs of LHC experiments, such as CMS, are expected to continue growing significantly over the next decade, during the Run 3 and especially the HL-LHC era. The SI team manages a set of federated HTCondor pools, currently aggregating around 400k CPU cores distributed worldwide, supporting the simultaneous execution of over 200k CMS computing tasks. In order to detect and...
Transient gravitational-wave (GW) signals have been discovered since 2015 by the LVK global network of giant, ground-based, interferometric detectors. It currently includes four instruments: the LIGO Hanford and LIGO Livingston detectors located in the USA, the Virgo detector in Italy – hosted by the European Gravitational Observatory (EGO) –, and the KAGRA detector in Japan. A key component...
Energy prices are reaching an all time high in europe and we are speculating at the same time to get a more elaborated billing model that calculates a real time electricity price depending on the availability of electricity on the market. As the price is predictable roughly 30h in forehand it seems to be desirable to not only know more about the energy consumption of a condor pool but also to...
The European Weather Cloud (EWC) is the cloud-based collaboration platform for meteorological application development and operations in Europe and enables the digital transformation of the European Meteorological Infrastructure. Among the services to be provided to the meteorological community, batch processing has been requested for several type of analysis using satellite data. HTCondor has...
The DUNE experiment is a large international particle physics
project which is currently under construction at Fermilab in
Illinois and SURF in South Dakota, with prototypes at CERN. The
experiment relies on Fermilab’s investment in HTCondor and
GlideInWMS, and on the LArSoft ecosystem of applications
software. Initially data management was done with Fermilab’s SAM
system but this is...
About a year a go we had a project that needs 20PB of low performance storage 20GBs throughout. We ended up buying 40PB with 2.7TBs throughout.
I would lime to share with you the journey from open source storage to commercial storage.
Choosing the technology, creating network to support this throughout, benchamrking, understand the needs and at the end real world vs the benchmark.

Making space for new groups within our existing dHTC infrastructure community is essential for "democratizing computation." This talk calls on participants to reflect on why so many research computing conferences have such homogeneous attendees. Some are long-term structural issues beyond our scope, but this should not absolve us from taking proactive measures to rectify this problem where possible.
