Description nbr 2007-08-29 15:45:38 MSD

For xmds differential equation solver it is better to have fftw libraries being
compiled with lam mpi. This allows it to work in LAM clusters.
Thanks if you do that.

Comment 1 Denis Smirnov 2007-08-29 16:41:27 MSD

Send patches please.
I don't have cluster hardware for test.

Comment 2 nbr 2007-08-29 16:43:14 MSD

No cluster hardware needed, just install lam and lam-devel packages and compile
it with option like enable-mpi.

Comment 3 Denis Smirnov 2007-08-30 05:28:37 MSD

It doesn't build with --enable-mpi.
libfftw-mpi doesn't link correctly with -Wl,--as-needed.
Makefile.am need to be patched.

Comment 4 nbr 2007-09-18 22:35:54 MSD

I put a version of xmds that has been compiled without MPI.
