Re: [bgl-discuss] MPI library on BG/L

[Sayaka Akioka <tobita@xxxxxxxxxxx>]

William, Rajeev, and everyone,

Thank you for your help!
Now I found that there are several approaches to realize what I am
trying to do. Especially for William's approach, I need to learn more
about MPI things, I guess.

I will consider each way for a while, and figure out what is the best
way for me.

Thank you,
Sayaka
