In openmpi: this error came when i run my mpiblast program on rocks cluster.Connect to hosts failed on ip 10.1.255.236,10.1.255.244 . And when i run following command

linux_shell$ perl -e 'die$!=113'

this msg comes: "No route to host at -e line 1."

shell$ mpirun --mca btl ^tcp
shell$ mpirun --mca btl_tcp_if_include eth1,eth2 
shell$ mpirun --mca btl_tcp_if_include 10.1.255.244

was also executed but it did nt recognized these commands....nd aborted.... what should i do...? When i run my mpiblast program for the frst time then it give mpi_abort error...bailing out of signal -1 on rank 2 processor...then i removed my public ethernet cable....and then give btl_tcp endpint error 113....

Edited to be readable.

I'm not sure if there is a question in there somewhere, but basically, I'd expect rather much knowledge about unix in general and HPC in particular to be required to set up and run a cluster with MPI programs.

It's certainly not impossible with no background knowledge, but I think it's very easy to underestimate the amount of learning (reading/experimenting) necessary.

As you seem to have established already, 113 means "no route to host".

rocks 6.0 cluster is automatic cluster installation a it uses kickstart.cgi communicated to other nodes via dhcp....and my main focus was to run mpiblast tool for dna sequencing on rocks...
