[mpich-discuss] SMPD passphrase?

Before launching a smpd job, one needs to get smpd running on a node with the command "smpd -s". This propmts the user to create a ~/.smpd configuration file and passphrase if it did not exist already.

I then tried to run the cpi example with the following result:

$ mpiexec -n 1 ./cpi.exe
Process 0 of 1 is on IT-00089
pi is approximately 3.1415926544231341, Error is 0.0000000008333410
wall clock time = 0.000000
os_error = 104 (Connection reset by peer)
SMPDU_Sock_wait failed,
sock error: Error = -1

state machine failed.

The same error would happen when launching two processes:

$ mpiexec -n 2 ./cpi.exe
Process 0 of 1 is on IT-00089
Process 0 of 1 is on IT-00089
pi is approximately 3.1415926544231341, Error is 0.0000000008333410
wall clock time = 0.000000
os_error = 104 (Connection reset by peer)
SMPDU_Sock_wait failed,
sock error: Error = -1

state machine failed.

Thank you very much for your help,
José

I think you need to configure a passphrase somehow.  I don't use windows so I have no specific idea how to do it.  I suspect, however, that the installer's guide on the mpich2 website contains this information somewhere.
