Join us at Super Computing 2011!We invite you to visit us at the SC2011 conference in Seattle, Nov 14-17 at Booth #2040 See first-hand how we are enabling research discovery with Dell HPC solutions.
This is a follow up to Part 1 of the Dell | Terascala HPC Storage Solution series. In this post I’ll go into a bit more detail about the solution – particularly how it’s administered via the GUI interface and I’ll also talk about some of the metadata performance results.Link to BlogScott Collier
There are many, many examples of how to set up SSH port forwarding online. Here’s how I do it. In our environment we have many clusters set up – behind a firewall. So, the challenge we have is to be able to efficiently log in and out of clusters and copy files to and from clusters. Link to BlogScott Collier

Regardless of the reason, when things are not consistent on your cluster you could encounter "anomalies" when running jobs, things that are broken now that weren't before. Part of administering a cluster is making sure everything is at the same version, and that can be difficult without the right tools.In this blog post, I'll talk about some of the tools I use to make sure my clusters are consistent.

If you find yourself having to update any firmware on your servers via DOS, instead of walking to each server and using a USB drive, or booting to a USB floppy, try it via PXE. In most cases we have a Linux based update package, so you can avoid updating in this manner.I am assuming that you have a functioning cluster at this point. In this example, we'll take a look at updating CPLD firmware on a PowerEdge M610.Link to BlogScott Collier
When you receive a new cluster you’ll want to test the various components to make sure everything is working. Here we’ll take a look at how to do some very basic Infiniband connectivity tests to ensure your links are up and running at the correct speed. Granted, there are several different tools and methods you can use, we’ll just cover a few. Link to BlogScott Collier -
If you find yourself in need of a tool that can change BIOS settings while you are still booted into the operating system, look no further. syscfg is a powerful tool provided by DTK (Dell Toolkit) that allows you to do just that. This article will cover using syscfg to change the number of CPU cores that are presented to the operating system.Link to BlogScott Collier
