Dear all,
I tried to recompile amber8 and tried to narrow the problem down, I found
out that if I use exactly same command:
$AMBERHOME/exe/sander -O -i md.in -o md.out -c model_min.rst -p
model.prmtop-r model_md.rst -x model_md.mdcrd
after the installation of serial part (without parallel part), it is OK. And
if i use it after finishing the parallel installation of amber, then I got
error message:
Unit 5 Error on OPEN: md.in
[0] MPI Abort by user Aborting program !
[0] Aborting program!
p0_12655: p4_error: : 1
Anyone can tell me what is wrong please? really appreciate your help.
Regards,
Rachel
