Hi!
These are the results:

DES (many/one salt)
     - MPI: 54410K/51601K
     - OMP: 47087K/21626K

LM
     - MPI: 786762K
     - OMP: 50823K (1)

NT
     - MPI: 533520K
     - OMP: 18498K (2)

NETLM (many/one salt)
     - MPI: 53168K/17572K
     - OMP: 27787K/865569 (1)

NETNTLM (many/one salt)
     - MPI: 53268K/39016K
     - OMP: 30736K/7077

(1) With OMP_NUM_THREADS=24
(2) Same result with OMP_NUM_THREADS={24,48}

I did real test and these are the results:

Crack LM Hash of "ex&31"
     - MPI: 1m
     - OMP: 29m

Crack LM Hash of "ex&314"
     - MPI: 1m
     - OMP: 55m

Crack LM Hash of "gol27$"
     - MPI: 27sec
     - OMP: 11m

With NT Hash the results are quite similar, there is a big difference 
between MPI and OMP.
I will publish the results on the wiki.
