XMT is Professor Uzi Vishkin's research project at the University of Maryland (http://www.umiacs.umd.edu/~vishkin/index.shtml). A brief description from SPAA'07: XMT (eXplicit Multi-Threading) on-chip general-purpose computer architecture is aimed at the classic goal of reducing single task completion time. It gives an easy general-purpose parallel programming model, and provides good performance with any amount of parallelism provided by the algorithm (up- and down-scalability). And this is the most striking: XMT is easy to program. There is a parallel programming course this semester for high school students. Hi Michael :)

It's a language that can perform as well as C or C++ and has had parallelism built (aka 'tasking model') into the language since its first incarnation (Ada83). Of course, back in those days that made way too many demands on the OS and it got a bit of a bad rep. but not a problem today. It should certainly knock points 3 and 5 on the head. The latest language revision added OO support to the tasking model, so you now derive from an active class. Check out https://libre.adacore.com/ for a free (beer & speech) compiler, IDE and add ons (XML, CORBA, Gtk, etc). And its not just the military that are using it. Digital TV, SatNav and Processor Fabrication are some of the more 'unheard' of users. Cheers -- Martin Have you tried Ada (specifically Ada2005)?
