High data throughput is a key feature in today's LHC analysis centres. This talk will present the approach of the DESY site Zeuthen to build up a high performance dCache out of commodity hardware. Additional optimisations to achieve further throughput enhancements will be mentioned, as well. By presenting current benchmarks we show competitive results compared to more expensive installations.

The third paradigm of research known today as e-Science requires that the computational sciences community rely heavily on HPC clusters to run their simulations. At the core of each cluster lie commodity devices with increasingly parallel capabilities. The two most successful processing devices today complement each other: the multicore CPUs and the manycore GPUs as accelerator vector devices....

Since PIC is supporting the data management of several scientific projects it is faced to requirements that might not be possible to enable in a homogeneous infrastructure. When looking for an alternative approach we have chosen to export the specific requirements into a virtualized environment. In order to minimize the impact to our physical computing infrastructure it was necessary to...

We have developed a method using Condor and a simple software component we call Cloud Scheduler to run High Throughput Computing workloads on multiple clouds situated at different sites. Cloud Scheduler is able to instantiate user-customized VMs to meet the requirements of jobs in Condor queues. Users supply Condor job attributes to indicate the type of VM required to complete their job....
