[OMPI users] MPI one-sided passive synchronization.

2011-04-13 Thread Abhishek Kulkarni
Hello, I am trying to better understand the semantics of passive synchronization in one-sided communication calls. Doesn't MPI_Win_unlock() block to ensure that all the preceeding RMA calls in that epoch have been synced? In that case, why is an undefined value returned when trying to load from a

[OMPI users] OMPI without-rte-support?

2008-08-11 Thread Abhishek Kulkarni
Hello, I downloaded the openmpi-1.4a1r19231 nightly and trying to configure it without RTE support. It doesn't seem to recognize the without-rte-support configure flag, or so it seems. It goes on well with "with-rte=no". $ ./configure --without-rte-support configure: WARNING: Unrecognized options
