Heat density: The Challenges of Compact Compute Nodes

With the popularity of physically smaller compute nodes like Advanced Clustering’s own Pinnacle Flex system, comes the issue of heat density. While the size of nodes is shrinking, the power draw of these systems is staying about the same, or going up with the addition of accelerators like GPUs, and Xeon Phi co-processors.

Powering Your Cluster

One item our customers often overlook when exploring the idea of a cluster purchase is their power requirements. Yet this is one of the most important elements of a cluster purchase, since it can affect cost, rack space and even the physical environment in which the cluster will be housed.

We haven't seen any molecular dynamics benchmarks on the newest processors: AMD Opteron (Istanbul) 6-core or Intel Xeon (Nehalem) 4-core. To help us get a better understanding of the performance on MD code, I took a look at two of the most common MD codes out there: LAMMPS and GROMACS. My results are a little surprising!
