Hybrid Programming for Shared-Memory and Clustered SMP Systems

There’s an upcoming workshop at the PSC September 8 – 11, 2008

This workshop will present programming models and techniques for writing efficient parallel code on contemporary and future supercomputers with extensive shared memory, or hierarchical architectures with smaller shared-memory components. Two important examples of systems to which these techniques apply are the SGI Altix and networked clusters of multicore processors. Expert instructors from PSC and SGI will review MPI, OpenMP, and hardware architecture prior to launching into detailed treatments of programming for hybrid parallelism, performance analysis, and optimization. This is a “bring your own code” workshop. Participants are encouraged to bring an application to focus on during the hands-on sessions to maximize the workshop’s effectiveness. Examples will be provided for participants who cannot bring a research code. Experienced PSC computational scientists will provide support regarding the topics covered, including hybrid algorithms and implementation strategies and performance engineering.

Ruby on Grids

Eric Rollins did some interesting tests with Ruby. It should be possible to run parallel tasks effectively with DRb. I am going to do some more playing around with this.

The Ruby fanfare on the net seems to be approaching the “multi-core” crisis and several bloggers are talking about Ruby as a language for parallel environments.
