I'm trying to build a 64 bit version of openmpi on a powerpc running
Mac OS X 10.4.7 and using a recent snapshot of gcc/g++/gfortran from
the gcc svn repository. The config and build process goes smoothly
but the result doesn't pass all the tests. It hans on the opal_if
test as well as simply running mpirun -np 1 hostname. The process
ramps up the member up to about 3.5G and the machine becomes very
sluggish (it has 8G). Has anybody seen this before or had experience
building on similar systems?
