Dear sirs;

    I am trying to run the REM amber code on a dec_alpha cluster (PSC). I

../configure -mpich compaqf90

and it all seemd to compile fine. There were no errors and got at the

Installation of Amber8 (parallel) is complete at Fri Jan 21 19:19:01 EST

But when I try to run the following command:

prun -N ${RMS_NODES} -n ${RMS_PROCS} -vvv ${HOME}/amber8/exe/sander -O -ng
4 -rem 1 -remlog ./rem.log -i ./ -p ./ -c ./md.r -o ./out -r

I get the following error message:

     mdfil: Error unknown flag: -rem

     usage: sander [-O] -i mdin -o mdout -p prmtop -c inpcrd -r restrt
                   [-ref refc -x mdcrd -v mdvel -e mden -idip inpdip -rdip
rstdip -mdip mddip -inf mdinfo -ra$
Consult the manual for additional options.
prun: /usr/users/1/swong/amber8/exe/sander (host iam576 process 0 pid
852746) killed by signal 6
prun: generating backtrace for /usr/users/1/swong/amber8/exe/sander
