Hi list,
I searched the archives, but didn't turn anything up...
I have a new machine which I've installed windows 8 x64 + MSVC 2012 (MSVC 11)
and have compiled openmpi from the git svn clone(on branch origin/v1.6) using
these settings ...
cmake -DOMPI_ENABLE_THREAD_MULTIPLE=true -DOPAL_ENABLE_MULTI_THREADS=true
-DOMPI_WANT_CXX_BINDINGS=false -DCMAKE_C_FLAGS:STRING=/MP
-DCMAKE_CXX_FLAGS:STRING=/MP -DCMAKE_INSTALL_PREFIX="%MPI_DIR%"
D:\Code\ompi-svn-mirror -DCMAKE_GENERATOR="Visual Studio 11 Win64"
The compilation succeeds, but when I run my app, I see that THREADS_MULTIPLE is
not set. So I tried running ompi_info and I see that it outputs the following
(at bottom of post), but locks up.
The stack trace when it locks up is as follows...
libmpid.dll!opal_atomic_cmpset_ptr(volatile void * addr, void * oldval,
void * newval) Line 198 C++
libmpid.dll!opal_atomic_lifo_push(opal_atomic_lifo_t * lifo,

My question is : has anyone tested msvc 12 and openmpi and can they recommend a
source version I can use to compile and enable threads. If this combination of
compilers etc is not yet supported, how can I help fix this. The fact that
ompi_info reports "Thread support: no" indicates to me that either the cmake
config is failing, or I've messed up with options. I tried the v1.7 branch, but
the cmake support appears flaky. I'm willing to either fix the 1.7 cmake or the
1.6 thread lock, if necessary, but I don't want to waste my time if it isn't
going to work within a reasonable amount of debugging. I welcome any advice on
how to get this compiling and working and offer cmake related help if you need
it to work on this platform.
NB. I think I said my program runs, but actually, with threads enabled it bombs
out during MPI_Init_thread(&argc, &argv, MPI_THREAD_MULTIPLE, &provided); - it
runs without threads, but I need them.
Thanks
JB
