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...

The recent release of the AMD "Llano" processors may not have attracted very much attention in the HPC world. It should have. The Llano processors are some of the first Fusionprocessors to hit the market. Simply put, the AMD Fusion processors are placing both the...

If you have read any of my articles and columns over the past several years, you will notice that I get on my "parallel programming soapbox" and browbeat anyone who will listen. My basic message is as follows. "Due to multi-core, everyone (who writes code)...

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...

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...

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....
