Hello Prakash
Thanks for replying man .I will try and put my issue in a detailed way.
See i have a MPI installed on 4 machines networked. with one being the
server on which i have a Mysql database installed.
Uptill now i had a perl program running serially on the server with string
comparison from the database , picks up a string and compares with ( n-1)
strings present in the database , so this takes up a lot of time as i have a
huge data which needs to be compared.
Now i am trying to run this job parallely. will i be able to run the same
script using the Parallel::MPI module.
How will the program run on multiprocessor accessing database present on the
main server.
I hope you got my point. I will really appreciate your patience to kindly
guide me on the same as i am stuck in this field as i am new to MPI.
Regards
Abhishek

Hello,
Yes. We do this all the time. But you should understand that the MySQL
database server becomes your bottle neck in this parallel environment.
In our case, we run the database servers also in parallel on the
scheduler assigned nodes. But this is very much application-specific.
Thanks,
Prakash
