ULLTraDIMMs, super fast storage

When companies work together, good things can happen. This is demonstrated by the collaboration of SMART storage and Diablo Technologies to develop a new line of ultra-low latency storage, the ULLtraDIMM.

HPC Cluster Blog - Oversubscribing Your Network?
Thursday, 06 February 2014 09:34

To oversubscribe your IB network or not:

When deploying an high performance computing cluster with more than 36 nodes that has an InfiniBand network, one of the most important considerations (beyond the bandwidth – QDR vs. FDR) is whether to oversubscribe or not. There are valid reasons for both approaches. Our first option is a non-blocking network - that is, where it operates at full wire speed. The primary consideration here is if there are any jobs that will run on this cluster can use more than 36 nodes. If there are, then the decision is pretty straightforward. You either buy a switch large enough to accommodate all of the available nodes or you set up a fat tree topology that provides for full bisectional bandwidth.

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

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.
