Breakin for hardware testing

My day job is in Beowulf clustering (I work for Advanced Clustering Technologies in Kansas City); it's pretty cool because it draws on every conceivable computer-related skill that one mights have: programming, scripting, architecture, data center design, Linux kernel hacking, user interfaces, message passing, compiler optimizations, BLAS, semi-high level math, hardware ... the list goes on and on. It's challenging enough without having hardware failures get in our way.

So, we developed an automated way to find and report hardware problems using a combination of the kernel's EDAC and MCE and lm_sensors, S.M.A.R.T., and hddtemp. It's a little initrd that boots up and puts the system under heavy, heavy load using a program called HPL (well-known in HPC) compiled against Intel and AMD-specific BLAS libraries. We've been using it internally for a few years but decided that others might benefit from it as well.

So, I set up a public git mirror here:

git clone http://git.advancedclustering.com/git/bootimage.git bootimage

And I put up some pre-compiled binaries and an explanation here: http://www.advancedclustering.com/software/breakin.html

If you have ECC memory, be sure to enable multi-bit checking in your BIOS.

Spiffy software
Very nice, will probably poke some folk to use in our datacenter. I noticed "cloner" on there as well - is that open source or not? It also doesn't seem to be available to download, despite the link to the download page...

Re: Spiffy software
Yea, it'll be open source. We're preparing it now; would expect it in the next month or two.
