I thought I would point you to some exciting work students are participating in over at Texas Advanced Computing Center.  TACC is mentoring several University of Texas at Austin students in the SC10 Student Cluster Competition to be held this November in New Orleans.  This is great work that the students are doing, and it is great to see involvement from TACC and support from the HPC community.  Here are some brief details of the SC10 challenge to build a system within the power constraints equivalent to only three coffee-makers!

The Student Cluster Competition (SCC) showcases the computational impact of clusters and open source software in the hands of motivated and sleep-deprived students under both a time and power constraint. Uh, no pressure…

During SC10, teams consisting of six students… will compete in real-time on the exhibit floor to run a workload of real-world applications on clusters of their own design while never exceeding the dictated power limit.

Prior to the competition, teams work with their advisor and vendor partners to design and build a cutting-edge commercially available small cluster constrained by the 26 amps available during the conference. Teams must also learn the four open source competition applications and are encouraged to enlist the help of domain specialists.”

It is exciting to see students motivated to work on some of the challenges we face in the industry.  I first met the two student leaders of this six-person group at SC09 in Portland last year. Read the rest of this entry »


One of my Dell HPC colleagues, Dr. Jeff Layton, has put together a great guide for getting started with Logical Volume Management on Linux.  LVM on UNIX based platforms has been around for a long time, but is relatively new (and now stable) on Linux within the last few years.

Over the years, I’ve used GUI volume managers on Solaris (Veritas), AIX (LVM), and HP-UX (SAM), but they were proprietary and expensive.  LVM on Linux is a great solution.  You may balk at using a GUI, but when you have your companies’ critical data on the line, there is nothing like “seeing” your volumes before you manipulate them.  For me, storage management was probably the most stressful part of UNIX/Linux system administration, because if you screwed up, you could lose data.  It is worthwhile to use all the tools at your disposal (even a GUI!) to make sure you aren’t, for instance, removing the wrong disk from the wrong logical volume.
