I am fairly confident I am just missing something very simple but . . . I have a (trivial) embarrassingly parallel scatter/gather code which compiles fine in both Java back-end and C++ back-end modes. The Java backend-version runs nicely using all the cores it can for the number of places specified in the code -- though the code runs excruciatingly slowly compared to Java or Scala. The point is I see the scaling that should be present. Using the C++ backend, it is nice and fast (essentially as fast as C++ coded version using asynchronous function calls a la C++0x) but it only ever runs on one core. So how do I get the runx10 command to map places to cores?
Am I just being very stupid and missing the line that tells me how to do this? Thanks. PS I remembers to switch off PGP signing before sending this one so hopefully it doesn't get rejected. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@russel.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder ------------------------------------------------------------------------------ The Next 800 Companies to Lead America's Growth: New Video Whitepaper David G.
