Parallel Programming - What Systems Do You Prefer?
atti_2410 asks: "As multi-core CPUs are finding their way into more and more computer systems, from servers to corporate desktops to home systems, parallel programming becomes an issue for application programmers outside the High Performance Computing community. Many Parallel Programming Systems have been developed in the past, yet little is known about which are in practical use or even known to a wider audience, and which are just developed, released and forgotten. Or what problems the actual users of parallel programming systems bother the most. There is not even data on the platforms, that parallel programs are developed for. To shed some light on the subject, I have setup a short survey on the topic, and I would also very much like to hear your opinion here on Slashdot!" What Parallel Computing systems and software have you that really made an impression on you, both good and bad?
From some recent experiences with the mpiblast project, and some much older work at llnl I've had better experiences with mpich as being more reliable than lam (one man's limited opinion, a data point not a rule). Also I think it should be more clear that mpiblast is perfectly usable in numa architectures. On first read of the parent I thought this was being ruled out. When debugging in parallel Totalview is a godsend, or was the last time I needed/could afford it. For geek points I'd have to agree that the worms remind me of Sarlacc.
