NVMe (Non-Volatile Memory express) is a leading-edge SSD technology
where drives are directly attached to the PCI-e bus. Typical
SAS/SATA controllers are optimized for use with traditional
rotating hard drives, and as such can increase latency, and
reduce the bandwidth available to attached SSDs. Since
NVMe drives bypass a SAS/SATA controller, they can help
minimize/eliminate...

Scheduling jobs with heterogeneous requirements to a heterogeneous pool
of computers is a challenging task. HTCondor does a great job supporting
such a general-purpose setup with features like Hierarchical Group
Quotas and Partitionable Slots. At BNL we have a model, configuration,
and software to handle the administration of such a pool, and in this
talk we will share our experience...

We are using Univa Grid Engine as BATCH scheduling system to our satisfaction since four years. We focus on the latest major version 8.2.1, which was deployed at IN2P3-CC 4 months ago, and provides further scalability improvements.
We are supporting about 200 groups and experiments running up to 17.000 jobs simultaneously. The requirements, in terms of computing resources, storage or...

The goal of the HTCondor team is to to develop, implement, deploy, and evaluate mechanisms and policies that support High Throughput Computing (HTC) on large collections of distributively owned computing resources. Increasingly, the work performed by the HTCondor developers is being driven by its partnership with the High Energy Physics (HEP) community.
This talk will present recent changes...

The RACF is a key component in BNL's new Computational Science Initiative (CSI). One
of CSI's goals is to leverage the RACF's expertise to shorten the time and effort
needed to archive, process and analyze data from non-traditional fields at BNL.
This presentation describes a concrete example of how the RACF has helped
non-traditional workloads run in the RACF computing environment, and...

So as to have our Batch Service at CERN answer increasingly challenging scalability and flexibility needs, we have chosen to set up a new batch system based on HTCondor. We have set up a Grid-only pilot service and major LHC experiments have started trying it out. While the pilot is slowly becoming production-ready, we're laying out a plan for our next major milestone: to run local jobs too,...
