Thank You very much. I think this is very useful for me. Can You provide me link to presentation (i can't see it under http://www.open-mpi.org/papers/) And can You send me very simple example, how can i use ORCM.. (may be i can get some useful information by reading http://svn.open-mpi.org/svn/orcm/trunk/test...) Does ORCM have man pages for functions like openmpi? -- Vasiliy G Tolstov <v.tols...@selfip.ru> Selfip.Ru
