Our first researcher using Amber PMEMD on the OSG reports molecular dynamics are four to eight times faster on the OSG than with the infrastructure she had access to previously. That’s for the all CPU version, i.e. without the Nvidia … Continue reading
PMEMD for OSG is live. Gratia statistics for January: All runs are 8-way parallel MPI jobs so we get eight hours of CPU time per hour of wall time.
The open science grid is a distributed heterogeneous network of computing clusters. Its infrastructure and protocols allow members to submit high throughput compute jobs for remote execution. All use is authenticated and authorized via a PKI infrastructure which associates jobs … Continue reading
Engage users log in to the submit host to run jobs on the OSG. It needs to move to a platform with better administrative support. It’s time to do some archaeology to find out what’s there then build a new … Continue reading
The Goal RENCI’s working with researchers interested in running high throughput parallel molecular dynamics simulations on OSG. Amber9 PMEMD The program we’d like to execute is called PMEMD (Particle Mesh Ewald Molecular Dynamics). PMEMD is a high-performance, parallel component of … Continue reading
