[mpich-discuss] problem executing cpi example program on remotehosts

[Rajeev Thakur]

Do you have a shared file system across the machines? If not, you will need
to explicitly copy the cpi executable to the remote machines.

remotehosts


Hello again,

I'm having troubles running the example cpi after having mpich2 running on
several (OSX) computers.  As you can see below, built-in commands work, but
the example cpi does not, as if the program is not being transferred to the
remote nodes.  I can ssh to any of these nodes and create files/folders
etc...:

problem with execution of examples/cpi  on  mb13.local:  [Errno 2] No such

thanks again,
