What is Sun doing in the High Performance Computing space ? The answer to that question is likely to surprise you, especially if you have not followed Sun for the last few quarters. Generally, what contributes to the answer are components that help enable technology solutions that 
meet specific requirements of latency-sensitive workloads. But the answer does not stop there. A solution typically spans various parts of the architecture stack, from the hardware, through the operating system software and up into the end-user's application. Availability of the operating system's libraries and operating system's intrinsic 
observability, virtualization and high availability capabilities become essential elements of an overall solution that business depends on. To that end, I had an opportunity to share in the fun of hosting a Sun solutions exhibit at this past September's High Performance on Wall Street event, at the Roosevelt Hotel in New York City. There were lots of interesting keynotes from customers who are actually facing these challenges and are working through them. Additionally, there were a number of interesting exhibitors sharing the exhibit halls with us. I, of course, talked about successes seen by our customers through the use of Solaris DTrace facility, our rich x64 AMD/Intel product line and various developer tools and solutions that have HPC requirements and capabilities inherent in them and examples of our joint work with Cisco, Intel and Reuters that has allowed for ....very interesting low-latency performance solutions for financial services customers. There's a global group of customer-facing archtiects and performance engineers (lead by Ambreesh Khanna) that is actually leading the charge on a number of solutions geared toward aiding our global financial customer base.
