Dear all, I had install my cluster which the configuration as following: - headnode : + linux CenOS 5.4, 4 CPUs, 3G RAM + sun gridengine sge6.0u12. The headnode is admin and submit node too. + Openmpi 1.2.9. In the installation openmpi :.configure --prefix=/opt/openmpi --with-sge ...Processes complilation and make was fine. + I have 2 others nodes which confg. are: 4 CPU, 1 G RAM and on which run sgeexecd. Testing for SGE on headnode and nodes by qsub was fine. When testing openmpi with as folowing: [guser1@ioitg2 examples]$ /opt/openmpi/bin/mpirun -np 4 --hostfile myhosts hello_cxx Hello, world! I am 0 of 4 Hello, world! I am 1 of 4 Hello, world! I am 3 of 4 Hello, world! I am 2 of 4 [guser1@ioitg2 examples]$
The openmpi runs well. My file myhosts: ioitg2.ioit-grid.ac.vn slots=4 node1.ioit-grid.ac.vn slots=4 node2.ioit-grid.ac.vn slots=4 Now for more processes: [guser1@ioitg2 examples]$ /opt/openmpi/bin/mpirun -np 6 --hostfile myhosts hello_cxx gus...@node1.ioit-grid.ac.vn's password: -------------------------------------------------------------------------- Failed to find the following executable: Host: node1.ioit-grid.ac.vn Executable: hello_cxx Cannot continue. -------------------------------------------------------------------------- mpirun noticed that job rank 0 with PID 19164 on node ioitg2.ioit-grid.ac.vnexited on signal 15 (Terminated). 3 additional processes aborted (not shown) [guser1@ioitg2 examples]$ This is error massage.
