Hi, I wrote about RDMA over TCP/IP (iWARP). Today I have installed mvapich2-1.6rc1 and openmpi-1.4.3 on my machine.
I don't know a lot about MPI code. I just try run hello file from example folder. [r...@redigo-01 examples]# ls connectivity_c.c hello_c.c hello_f77.f Makefile README ring_cxx.cc ring_f90.f90 hello hello_cxx.cc hello_f90.f90 Makefile.include ring_c.c ring_f77.f [r...@redigo-01 examples]# pwd /root/openmpi-1.4.3/examples COMMAND LINE: A) [r...@redigo-01 examples]# mpiexec -n 6 /root/openmpi-1.4.3/examples/cpi problem with execution of /root/openmpi-1.4.3/examples/cpi on redigo-01.lnl.infn.it: [Errno 2] No such file or directory B) [r...@redigo-01 examples]# mpirun rsh redigo-01.lnl.infn.it_59240 hello redigo-01.lnl.infn.it_59240: host unknown redigo-01.lnl.infn.it_59240: host unknown trying normal rsh (/usr/bin/rsh) redigo-01.lnl.infn.it_59240: Unknown host I write the mod.conf (as root user) file and I put it with correct permissions in /etc directory. I don't understand where is my error? Could you help me with these first steps in MPI? Thank you very much.
