I have a cluster nodes containing 2 PCs.How can i run specific exe file from one node in other node(for example from node 0). I must run executable file simultaneously for parallel run from command prompt in the first node. But when i run mpiexec -n 2 -ppn 1 -f host.txt c.exe in the first node this error appear. Host file just containing IP addresses of nodes and all exe file are in a same location in all nodes. How can i solve this? Thanks
