Things you should never do to a customers' machine/disk: Part 10, bricking a drive

Ouch.
We test our JackRabbit and Delta-V (ΔV) units extensively … long burn-in times, after any firmware updates. We like to run into the problems in-lab as compared to in-field. Some customers get annoyed at what they perceive to be slow shipping, but we want to know, when it leaves our lab, that this machine, and all its parts, works.

Nail, hammer, hit hit hit!

John West has a great commentary at InsideHPC.com. First I recommend, if you haven’t read it, by all means, read it.
He points out that Addison Snell (a former colleague during SGI days) stands by his HPC spending/market analysis of several months ago. Further, he notes something I saw in another press release recently, that indicates that financial services firms are remaining committed to HPC.

Working on Cuda+Fortran

So we have something like 5 different Cuda capable machines in the company. My laptop, an older Quadro FX 1400 based Opteron 275 based machine, a GeForce 8800 based machine, a dual GTX260 based machine, and a Tesla machine with 3 GPUs. The latter is to be our new desk(side|top) personal supercomputer offering. Pegasus-(I|A)(3|4)G. Complex .. dealing with case/PS issues now … rest of it works fine. Current unit is powered by a Shanghai pair which we are testing with. I am quite impressed with it … the 2.3 GHz Shanghais are showing themselves to be competitive with the high end of the Intel line. Next months (hopefully) Nehalem launch should change this a bit.
The nVidia folks asked me to work on something, to prove a concept. Looks like I am about 50% of the way there with about an hour of work with Cuda. I am tired, so I am gonna call it a night, but I expect to be able to get baseline testing done tomorrow.

stretching my (g)fortran legs …

Working on a quick project for a partner. I haven’t done much fortran programming in the last few years, mostly C, Perl, and a few other things.
Its been a while, but now I am remembering why I disliked multi-language programming in the past. You have to fight with the linkers (and compilers) to get them to do the right thing. Stuff that should “just work” doesn’t.
