parallel problem about VASP
Posted: Wed Nov 29, 2006 2:27 am
My computer has 4 cpus(only 1 node), and I want to run VASP in parallel. I compilered VASP by mpf90 without errors.
I change the machine file as "hostname:4"...
However, when I input "mpirun -np 4 vasp", it outputs:
running on 4 nodes
distr: one band on 1 nodes, 4 groups
vasp.4.6.26 15Dec04 complex
POSCAR found : 2 types and 44 ions
then nothing responded and exited.. there is no process running...
In order to test, I ran "mpirun -t -np 4 ", it output:
rsh localhost cd vasp/vasp_case/test/; env GMPI_SHMEM=1 GMPI_MAGIC=9106528 GMPI_ID=0 GMPI_NP=4 GMPI_BOARD=-1 GMPI_SLAVE=127.0.0.1 vasp/vasp/vaspmpi
rsh localhost -n cd vasp/vasp_case/test/; env GMPI_SHMEM=1 GMPI_MAGIC=9106528 GMPI_ID=1 GMPI_NP=4 GMPI_BOARD=-1 GMPI_SLAVE=127.0.0.1 vasp/vasp/vaspmpi
rsh localhost -n cd vasp/vasp_case/test/; env GMPI_SHMEM=1 GMPI_MAGIC=9106528 GMPI_ID=2 GMPI_NP=4 GMPI_BOARD=-1 GMPI_SLAVE=127.0.0.1 vasp/vasp/vaspmpi
rsh localhost -n cd vasp/vasp_case/test/; env GMPI_SHMEM=1 GMPI_MAGIC=9106528 GMPI_ID=3 GMPI_NP=4 GMPI_BOARD=-1 GMPI_SLAVE=127.0.0.1 vasp/vasp/vaspmpi
I don't know how to deal with this problem and I appreciate your suggestions!
