I am new subscriber. I installed LAMMPS program in Opteron cluster. Program runs very well as a parallel. But when i use
hybrid type pair style, program fails. In my input file i use pair style like as that:
pair_style hybrid lj/class2/coul/long 10.0 buck/coul/long 10.0 lj/cut/coul/long 10.0
Error message that i get is:
Setting up minimization ...
1 - MPI_WAIT : Message truncated
 Aborting program !
 Aborting program!
OOPS: semop lock failed
/opt/mpich-1.2.7/ch_shmem/bin/mpirun.ch_shmem: line 91: 4700 Aborted /root/LAMMP/lammps/lammps-27Oct07/examples/test/./lmp_pg
As i told that this only happens when i use hybrid type pair style. Could anyone help me to solve this problem?
P.S: To Solve "semop lock failed" problem, i use "cleanipcs" command. But it did not help. I also tried to increase stacksize with ulimit. This also did not work.
I appreciate if somebody helps me.
