NIKHEF Grid and Physics Data Processing
Nikhef, the Dutch National e-Infrastructure, and Netherlands Tier-1The Large Hadron Collider (LHC) alone produces rougly 30 Petabytes of data anually. And by 2014 the LOFAR radiotelescope had exceeded all LHC experiments combined with regards to data stored on tape in the Netherlands. And meanwhile bioinformatics, from tomato genomes to structural chemistry, face icreasing need for computation and data analysis. The federated e-Infrastructures combine large-scale distributed data processing centres across many different institutes and countries, that together enable the analysis of these data. In support of its mission and in order to strengthen the global e-Infra and cyber-infrastructure ecosystem, Nikhef has been participating since 2000 in many European and global project like DataGrid, EGEE, AARC, and EOSC-Hub, amongst others, that have helped share and operate this federation. Together with NWO and NBIC we proposed and won the BiG Grid project to provide a large-scale e-Science infrastructure in the Netherlands, putting down the foundations for the Dutch National e-Infrastructure, the DNI, coordinated by SURF. The Netherlands Tier-1 Facility is enabled by the DNI and jointly coordinated with SURFsara as part of the national e-Infrastructure - as are many more sciences. Nikhef also promotes e-Science solutions and infrastructure for collaboration such as Federated Identity and Access Management, and has participated in many joint grid projects in Earth observation, the humanities, in astro-particle physics, for LIGO/Virgo, Xenon, Lofar, and other data intensive sciences.
The use of federated compute and data technologies greatly facilitates implementation of the distributed model for simulation and analysis, and enables efficient use of the computing and storage resources by the various experiments.
Besides the global federated infrastructure, Nikhef also avails over a large local analysis cluser ("Stoomboot") and an associated high-performance disk system based on dCache ("/dcache") of about one petabyte.
Getting onIf you are at Nikhef, computing and storage in the Netherlands, in the LHC Computing Grid, and through the European e-Infrastructure are available for your use. To make your experience, follow these simple steps. For help, you can always drop by at any room between H1.50 and H1.59!
Our resourcesThe NIKHEF Data Processing Facility comprises a single production facility (LCG2ELPROD) and some smaller experimental systems. The facility contains over 5700 CPU cores of compute power and about 5000 TBytes of disk space. All of this is connected with 1.2Terabit of interconnect network and there is 250 Gbps of internetworking bandwidth available. Some of this capacity is dedicated to usage by the WLCG community (and our local physicists), whilst all participants and users of the Dutch National e-Infrastructure coordinated by SURF can use it! The Nikhef facilities are predominantly distributed high-throughput data clusters interconnected globally, and high-throughput cloud. An even karger range of facilities is offered in the Netherlands - for those have a look at SURFsara.
Our ResearchThere are three main lines of Grid and fabric research and engineering of the NIKHEF PDP group:
