Is HPC in the cloud right for you?

Over the years, I’ve attended many birds of feather where the topic was whether or not there was a future in moving HPC into the cloud.  There were plenty of vigorous debates for and against, and they tended to go this way:

 

For:

The most obvious argument for moving your computing to the cloud is eliminating the need for purchasing and maintaining hardware.  Most of the users are scientists or engineers who don’t want to spend their time managing a cluster.  By moving to the cloud, they allow others to buy, power, cool, and maintain the hardware while they focus on what they’re experts in.  The actual cost of a cluster is substantial, and the costs to house it, power it, and cool it are not insignificant.  Then, of course, someone has to administer and maintain it.  But there are many professors and engineers where this responsibility falls to them.  So, now they have to hire someone to maintain it, or do it themselves.  And if that’s the case, it takes away from their ability to do science.  With the cloud, you simply upload your data to the online resource, pay for the cycles you need, and once the job is complete, download the results to your local machine and do your work.  If you do not require constant access to a cluster to run your jobs, then this could be a viable option.

HPC Cluster Blog - Xeon Phi

Xeon Phi, is it right for you?

With Intel’s release of the Xeon Phi back in 2012, there has been a lot of interest, and a lot of misunderstanding of what it is and how it works. The Phi can provide a great performance bump for the right application and use case. To understand if the Phi would be useful to you, first we need a little background.

The Xeon Phi is an accelerator card, it’s a PCI-e expansion card that provides 50+ x86 style cores, with its own memory, interconnect, and operating system. There are multiple models that provide different core counts and memory sizes, which is outside the scope of this article. Contact This e-mail address is being protected from spambots.

Cluster interconnects: the three basic configurations

While processor speed, memory amount and number of nodes in your cluster are important, another serious consideration for overall cluster performance is the interconnect. The term "interconnect" refers to the cabling and switches used by the nodes to communicate with each other. While necessary for every cluster, it becomes particularly important with highly parallel computing, where calculations are split among nodes to be solved simultaneously.
