Hi,
I am trying to build Open MPI 1.4.3 with thread support on Windows. A
trivial test program
runs if it calls MPI_Init or MP_Init_thread(int *argc, char ***argv, int
required, int *provide) with
reguired=0 but hangs if required>0. ompi_info for my build reports that
there is no thread
support but MPI_Init_thread returns provide==required.
The only change in the CMake configuration was to check
OMPI_ENABLE_MPI_THREADS.
Is there anything else that needs to be done with the configuration?
I have built 1.4.3 with thread support on several linuxes and mac and it
works fine there.
Not all Windows compilers work well enough with all threading models
that you could expect satisfactory results; in particular, the compilers
and thread libraries you use on linux may not be adequate for Windows
thread support.
