Almost, I commented out that test and then I get some errors in the REM
calculations. Apparently it can't re-write the rem.out.00* files. It
completes the first run (up to step 100), but when it has to re-start
again and write a new out file, it says
Unit 6 Error on OPEN: ./rem.out.000

and the same for rem.out.001. The other tests, however, run fine.

Running regular (serial) sander is fine. All tests pass.

if I use -np 4 , then I get the following message:
cd tgtmd/change_target.ntr; ./Run.tgtmd
SANDER: Targeted MD with changing target and restraints
DO_PARALLEL set to mpirun -np 4
too many processors for this test, exiting

OK, I recompiled with the options you specified and still get the same
error when running the change_target.ntr test. Ugh. I used the old
compiler for this last test. The new compiler (v 10) fails to compile.
Apparently the naming conventions are somehow different and it claims some
functions are delared multiple times.
Thanks
