Hello, everyone,

       I want to know how mpiblast handle the input and output files. For
example, if I run:

mpirun -np 5 mpiblast -d ecoli.nt -i input -o output -p blastn

5 processes would be started in the cluster, and each one copies small piece
of the database to its local folder. How about the `input' file? Is it
distributed
to all workers by rank 0? What about `output'? Does rank 0 collect data from
all workers and write them into output? It's kind of you explain the
workflow
of mpiblast, for I am a newbie to it.

Best

Andrew
