High Performance Humanities

The NEH and DOE have a vision to bring one million hours of high performance computing time to the humanities. The effort is being managed out of the NEH's new Office of Digital Humanities, created recently to recognize the increasing importance of computing in what has traditionally been a very old-fashioned area of research.

Compilers and More: Accelerating High Performance

Accelerators have been receiving a lot of attention lately from high performance computing users. PGI's Michael Wolfe thinks they should be getting even more. According to him, accelerators represent a more natural platform for HPC parallelism than either the current crop of general-purpose multicore chips or the ones on the drawing board. The trick is how to program them.

InfiniBand Goes Long

Since InfiniBand came onto the scene, users have focused their efforts on using the high performance network fabric to connect compute and storage boxes within the datacenter. But a couple of enterprising companies, Network Equipment Technologies and Obsidian Research Corp., have developed InfiniBand connectivity for wide area networks.

The Green Grid's Datacenter Metrics

The Green Grid has proposed key metrics for end user organizations to monitor as it pursues its goal of helping its members create more efficient datacenters. But what do the quantities mean, and how should they be measured? HPCwire talked to Jim Smith, the vice president of engineering for global datacenter operator Digital Realty Trust for lessons from his experiences measuring the health of datacenters in a business that looks a lot like HPC, but where a kW/h saved is a dollar earned.

AMD Redraws Server Processor Roadmap
On Wednesday, AMD presented its revised server processor plans for the next couple of years. The roadmap included the upcoming 45nm Shanghai chip, new six- and twelve-core Opteron processors, and the next-generation socket for DDR3 and PCIe Gen 2. AMD's new path also gives us some idea why Cray decided to play nice with Intel.
