Hi Shan,

I can't reproduce this problem exactly but everytime I try and run
sander.QMMM from Amber 8 on AIX I get the following error:
exec(): 0509-036 Cannot load program ./sander.QMMM because of the following
errors:
0509-026 System error: There is not enough memory available now.
This is really weird as hpmcount returns that the resident size of the code
is only 824KB. Plus the stack and memory limits are set to unlimited...
To be totally honest I wouldn't bother with QMMM in Amber 8. If you want to
do QMMM calculations you should seriously consider using amber 9. I would
just delete the sander.QMMM executable from the exe directory to stop
anybody 'accidentally' using it and then edit $AMBERHOME/test/Makefile and
change the serial: line from:
serial: test.sander test.sander.LES test.sander.QMMM \
test.nmode test.anal test.ptraj test.leap test.resp \
test.antechamber test.pbsa
to
serial: test.sander test.sander.LES \
test.nmode test.anal test.ptraj test.leap test.resp \
test.antechamber test.pbsa
Then you can re-run the tests. Everything else should work okay so it will
just be the QMMM functionality that you are missing.
All the best
Ross
