Announcement - Jacquard, DaVinci and Bassi join Open Science Grid


One of the NERSC clusters is named for Italian scientist Laura Bassi, who taught Newtonian physics for 28 years. Bassi was the first woman to officially teach at a college in Europe. 

The National Energy Research Scientific Computing Center, part of the Open Science Grid, has announced the introduction of their Jacquard, DaVinci and Bassi clusters to the OSG infrastructure.

The move marks a significant increase in the ability of OSG users to perform complex and high performance parallel processing, such as that required for interdependent rather than “embarrassingly parallel” problems.

Traditionally OSG has been geared towards serial or distributed processing: applications that pose hundreds of variations of a similar problem, such as typical applications in high energy physics or bioinformatics.

The NERSC clusters will enable complex or high performance parallel processing, such as that required for composite climate or flame simulations, as well as other applications where there are interdependencies between problems.

For example, the Jacquard cluster provides researchers with 712 processors, with up to 2.14 terabytes of aggregate memory delivered to a single OSG job.

This means researchers can solve far larger scientific problems than can fit into a typical single grid compute element. Typical workloads on these parallel resources require hundreds of cpus per individual job.

The clusters are predicted to broaden the appeal of OSG and to engage new virtual organizations with a need for parallel computing.

Users need to register before accessing these NERSC resources.
