15. Evaluation of the impact of various local data caching configurations at Tier2/Tier3 WLCG sites

Andrey Kiryanov (NRC Kurchatov Institute PNPI)

6/9/20, 10:45 AM

In this talk we will describe various data caching scenarios and lessons learned. In particular we will talk about local data caches configuration, deployment, and tests. We are using xCache, which is a special type of Xrootd server setup to cache input data for a physics analysis. A relatively large Tier2 storage is used as a primary data source and several geographically distributed smaller...

13. Access Pattern Analysis in the EOS Storage System at CERN

Olha Chuchuk (CERN, Taras Shevchenko KNU)

6/9/20, 11:00 AM

EOS is a CERN-developed storage system that serves several hundred petabytes of data to the scientific community of the Large Hadron Collider (LHC). In particular, it provides services to the four largest LHC particle detectors: LHCb, CMS, ATLAS and ALICE. Each of these collaborations uses different workflows to process and analyse its data. EOS has a monitoring system that collects detailed...

27. Dynamic Computing Resource Extension using COBalD/TARDIS

Ralf Florian von Cube

6/9/20, 11:15 AM

Cloud providers, HPC clusters, and free institute resources can dynamically increase computing power. In order to make theses so-called opportunistic resources transparently available, the services COBalD and TARDIS are developed in collaboration of the Institute of Experimental Particle Physics (ETP) and the Steinbuch Centre for Computing (SCC) at KIT.
The opportunistic resources are...

25. Publishing multi-purpose data sets from KM3NeT

Jutta Schnabel (Erlangen Centre for Astroparticle Physics (ECAP/FAU))

6/9/20, 11:30 AM

The KM3NeT neutrino detector, consisting of several building blocks for the water Cherenkov detection of relativistic charged particles, is currently under construction at various deep-sea locations in the Mediterranean Sea. As inter-domain experiment between neutrino, astroparticle and astrophysics, data processing and data publication from KM3NeT draws on computing paradigms and...

4. A review of methods of resolution estimation for 3D reconstructions for nanoscale biological objects from experiments data on super-bright X-ray free electron lasers (XFELs)

Ms Kseniia Ikonnikova (National Research Center «Kurchatov Institute»)

6/9/20, 11:45 AM

The ability to investigate 3D structure of biomolecules, such as proteins and viruses, is essential in biology and medicine. With the invention of super-bright X-ray free electron lasers (XFELs) the Single Particle Imaging (SPI) approach allows to reconstruct 3D structures from many 2D diffraction images produced in the experiment by X-rays scattered on the biomolecule exposed in different...

3. Modifications to the EMC algorithm for orientation recovery in Single Particle Imaging experiments on X-ray free electron lasers

Mr Sergei Zolotarev (National Research Center "Kurchatov Institute")

6/9/20, 12:00 PM

The emergence of super-bright light sources - X-ray free electron lasers(XFELs) combined with Single Particle Imaging(SPI) method, makes it possible to obtain nanometer resolution 3D structure of biological particles such as proteins or viruses without needing to freeze them. SPI relies on the “diffraction before destruction” principle, meaning that each sample only produces a single...
