Actually, I did have the problem with stack size limits, and they
magically disappeared when I stopped using -static. But, the program
crashes for another reason (obscure one,
not easy to debug because IFC8's -g flag causes PMEMD to fail to
compile. Bob- have you seen this as well?) if I compile with -static.
For those of you using mpd, if you do not want to modify
/etc/ld.so.conf, use an mpirun command line like:
mpirun -wdir `pwd` -m machines.all -np 8 -g 2 ./pmemd -O -i mdin -p
prmtop -c inpcrd.equil -o mdout -MPDENV-
LD_LIBRARY_PATH=/home/dsd/intel_compiler/compiler80/lib
The -MPDENV- part at the end sets the LD_LIBRARY_PATH in the child
pmemds running within the MPI environment.
