This has been another banner year for the day job

For the last 4 years, we’ve had significant year over year growth. We set records every year. 2 years ago was a barn stormer of a year. Last year reset the definition of barn storming for us. And this year. Yes, this year. I’ve hinted that we were following a hard/fast growth path. Some folks […]

OT: Helping a good cause

A few months ago, we had a new addition to our family. This is Captain, and he is what is called a rescue dog. The organization that rescued him doesn’t have that as their primary mission, they build shelters and provide food for dogs whom are chained up outside. Our Captain was one such. He […]

SC12 video

If you haven’t figured it out, I’ve been busy. This is the very good sort of busy. Rich at InsideHPC.com (you read this, right? Regularly? Right? You should if you don’t) did a whole set of interviews at SC12. There’s some very cool stuff in them. Here’s ours. I’ll tell you the funny stuff at […]

Microsoft OSes will likely be losing OpenMPI support

I’d been holding off on posting anything on this for a while to see if any group steps up to support it. It looks like this is simply not happening. One shouldn’t infer anything about the Microsoft platforms w.r.t. HPC as a result of this one case. However, in light of the absorption of the […]

The downside to social media

… there are SOOO MANY things to update, pay attention to … Yeah, its heaven for those of us blessed with ADHD (squirrel!), but it takes away time from important things. And of course, there is at least a little irony in blogging about this and having it auto-tweeted. The world doesn’t need more social […]

Wondering aloud

Call this a hypothesis based upon observation. Its harder for smart people to admit they are incorrect about something, than it might be for the population as a whole. My rationale works like this … the smarter you are, the more defensive you are of that ‘status’ if you will, and so you tend to […]

Updated DeltaV4 quick benchies

Streaming reads and writes. Far beyond memory/cache/… all spinning disk. Remember, this is our “slow” storage.
