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
In this post I’ll cover a few details, in hindsight, of setting up the Blueridge CE. There is plenty of documentation on how to set up an OSG compute element. Some of it is referenced from other posts on this … Continue reading
Baby steps. This is pmemd compiled against native MPI libraries executing on the RENCI Blueridge cluster. The job submission workflow uses the RENCI-CI script library. The job_run script uses Globus tools to transfer the pmemd application and input files to Blueridge. … Continue reading
