I think I successfully installed OpenMosix in every nodes. And by 
test(the small program recommended by lots of guide), I am sure the 
cluster is able to migrate jobs properly. 

But I have trouble make blast command line execute in every node.

And don't you think openmosix is suitable for blast cluster? You suggested 
SGE?
