A new paper from ORNL’s Sparsh Mittal and Jeffrey Vetter seeks to change the mindset of researchers using GPUs. Entitled, “A Survey of CPU-GPU Heterogeneous Computing Techniques,” the paper contends that merely offloading computational tasks to GPUs is not optimal, instead, using both CPU and GPU can lead to potentially higher speedup.

PNNL Looks at Undervolting to Meet Exascale Goals
May 25, 2015 by
PNNL researchers are using supercomputers to take on two of the main challenges of exascale: energy efficiency and resiliency. Their simulations show that dynamic voltage scaling, also known as undervolting, can reduce power consumption and leverage existing mainstream resilience techniques at scale for improving system failure rates.
Lustre & Kerberos: In Theory and In Practice
May 25, 2015 by
“Kerberos is the most famous way to allow safe communications over a non-secure network, by providing authentication and encryption. This presentation will show how far Lustre can go in Kerberos security, and what kind of authentication and encryption we can get to work. We will also take an interest in the impact of various Kerberos flavors over performance.”
