Number of Cores (VN mode)
o Scalability tests
–Search a quarter million of
randomly sampled sequences
against the database itself
–Achieve 93% parallel
efficiency on 32768 cores (8rack BG/P)
o Complete genome-to-genome
comparison
–Finish searching 16 million
vs. 16 million sequences within
12 hours
