[mpich-discuss] MPI Questions!

[Renato Tegon Forti]

Hi All,

I have 2 questions! If anyone can help-me!

One introduction:

I have one MPI program that use "self-scheduling" architecture. 

This program never ends! The "master" scan one data base (continuously in 5
and 5 secs) and always get new work and distribute these new works to
"slaves". 

Questions:

1)    I start my MPI using this command:

mpiexec -f hosts.txt -n 10  process_engine 

 

Have any way to run MPI program detached from terminal, like a daemon? I
need start my MPI program and close terminal! And MPI program need
continuously run in background.

 

2)    This scenarios introduces a new problem:

I need get all generated information (from master and slaves) and log on a
centralized log.txt file!

 

My slaves are running in 10 different machines, how log all information in
one log.txt that is in machine that start batch? (1)

 

Thanks for help!
