Introduction Hadoop has become a fixture where big data is concerned but it has been difficult to use in HPC and HTC cluster environments. This is becoming unfortunate as an increasing number of new algorithms assume Hadoop’s an option. I … Continue reading

Molecular Dynamics Proteins are important and their structure complex. And then they move. The way they move determines how organisms work … or fail. The shape of the protein determines its function so motion means its shape is in flux … 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
