On this list there is almost unanimous agreement that MPI is the way to go for parallelism and that combining multi-threading (MT) and message-passing (MP) is not even worth it, just sticking to MP is all that is necessary.
However, in real-life most are talking and investing in MT while very few are interested in MP. I also just read on the blog of Arch Robison " TBB perhaps gives up a little performance short of optimal so you don't have to write message-passing " (here: http://softwareblogs.intel.com/2007/11/17/supercomputing-07-computer-environment-and-evolution/ ) How come there is almost unanimous agreement in the beowulf-community while the rest is almost unanimous convinced of the opposite ? Are we just tapping ourselves on the back or is MP not sufficiently dissiminated or ... ? toon
