Okay, let's try spreading them out more, just to avoid putting more on a node than you actually need. Add -bynode to your cmd line. This will spread the procs across all the nodes. Our default mode is "byslot", which means we fill each node before adding procs to the next one. "bynode" puts one

Hi Björn, Why not giving CMake a try? It has been supported on Windows platforms and the building process is nearly 5 times faster then building under Cygwin. Regards, Shiqing On 2011-10-15 11:34 AM, Björn Adlerborn wrote: Hi, Im trying to build openmpi v1.5.4 on my windows xp machine usin
