My system OS X 10.7, Imac intel I7

I have 1 question :

I run your version (openmpi) , I get

mpirun -np 4 ./john -format=raw-md5 -test
iMac-de-xxx-xx:run xxxxxx$ mpirun -np 4 ./john -format=raw-md5 -test
Benchmarking: Raw MD5 [SSE2i 10x4x3]... Benchmarking: Raw MD5 [SSE2i 10x4x3]... Benchmarking: Raw MD5 [SSE2i 10x4x3]... Benchmarking: Raw MD5 [SSE2i 
10x4x3]... DONE
Raw:	21050K c/s real, 21261K c/s virtual
DONE
Raw:	21037K c/s real, 21248K c/s virtual
DONE
Raw:	20534K c/s real, 20534K c/s virtual
DONE
Raw:	21354K c/s real, 21354K c/s virtual


 With my own version (mpirun) I get :

iMac-de-xxx-xx:run xxxxxx$ mpirun -np 4 ./john -format=raw-md5 -test
Benchmarking: Raw MD5 [SSE2i 10x4x3]... (4xMPI) DONE
Raw:	54812K c/s real, 54812K c/s virtual

 As you can see there is only 1 result : 54812K c/s real (for 4 cores)

1)  Why is your version display 4 results (21+21+20+21K c/s) , and only not 1 (54812K c/s) ?
 - Is it possible to display only 1 result for all cores ?


 Thanks,

 W/A/
