I read some post = saying the blast patch for openMosix makes the search 20% slower. I want = to know whether I can get better performance with MPI. I read your posts saying "splitting the query sequence into small = fragments and BLASTing each of those fragments against the (entire) = database is super-easy to implement." Could you please tell me how to = combine the results, or a link to the solution would be very helpful? Thanks for your time and assistance.
