Cannot run with the new release v4.3

paulzhang · August 25, 2016, 04:58

The same configurations are used to compile
./configure CXXFLAGS="-O3" --enable-mpi --with-cc=/usr/local/mpi3-dynamic/bin/mpicc --with-cxx=/usr/local/mpi3-dynamic/bin/mpicxx
CGNS flag is no need to enable since the new version has already taken care of it.

The older version compiled using the same flags, working without any problem. But when it came to the v4.3, a couple of issues when ran the quicktest,
1. segmentation fault after the Begin Solver.
2. when using multi-cores, got multi-thread outputs. Must be something wrong with the mpi.

Does anybody else have a similar issue? Or it is just my problem.

Thanks,
Paul

Guess there is something weird with my make.

1. If my initial compile using single processor $make -j 1 all, it is workable. Otherwise the compiled binary fails to use multi-processors in the run. It always take it serial.

2. However, once compiled successfully, my later compile can always use $make -j 8, and I do not see any problem.
