No Cores For You!

Recently, I was curious about the cost of multi-core high performance workstations. I was looking for the latest and greatest at least eight cores, possibly more. With the growth of multi-core, I am always interested how many “SMP cores” you can get in a workstation.

More Multi-core Memory Testing

As mentioned previously, I have been planning to benchmark some new low power AMD and Intel Quad cores. My motivation is the Limulus Project. Even though these processors are low-power desktop devices they work similarly to their big brother HPC versions. When Intel or AMD

It Still Does Not Work

I’m in the middle of solving another cluster problem. I won’t mention any names or vendors, although at times I think some healthy shamming may be in order. In any case, the problem started out simple enough. I was asked to make a small change

HPC On A Need To Know Basis

One of the reasons I did not make a blog earlier in the week was the 2011 Lehigh HPC Symposium. The event was quite good, although I had to leave early. The program included both presentations on applications and implementation of HPC. The presenters included

High Tech Storage Lockers

Clouds, the next big thing, are not really for me. Call me a conspiracy theorist, paranoid, over protective, or a crank. The whole cloud thing sounds good at first. Cheap storage with no worries. But at some point you have to ask some tough questions

Got Cores?

The following Google announcement crossed my desk today; 1 billion computing core-hours for researchers to tackle huge scientific challenges. I am always intrigued by large numbers of cores or in this case “core-hours.” Reading further the announcement states: … academic research grant program called Google

Evaluating Multi-core for HPC

I plan on benchmarking several low cost quad-core processors in the coming weeks. I’m trying decide what to use in my Limulus Project upgrade. Currently, it uses Core 2 processors (three dual core and one quad-core) and while it works quite well, I want to

Cluster Tweaks For The Rest of Us

I’m a big believer in wiki’s because I don’t like repeating myself. Instead of telling someone about Computational Fluid Dynamics (CFD) packages for clusters, I would rather send them a web page link. Another reason I like dumping notes and information into a wiki is

Cloud-onomics for HPC

Let’s suppose you need to do some HPC. You have $50K to buy a cluster or use an HPC Cloud. For the sake of the example, let’s also assume your application works equally well with a cloud or local cluster. What should you do? The
