HPC

Last fall, I decided to purchase an SSD (Solid State Disk). The prices have come down and it makes sense to at least try one of these devices. SSD technology is interesting because every time you write to the drive, it degrades. Of course the...

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...

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...

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...

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...

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....

Previously I wrote about my Linux SSD Experience. I have been using the system for a while and have become quite accustom to SSD speeds. A 64 GByte SSD can be had for just over $100 and is well worth the investment. A typical Linux...

I am often asked, "Is it hard to write parallel programs" The short answer is a resounding "yes." My answer is sincere and my intention is to scare away those that don't like a challenge. Like many programming questions, the devil is in the details...
