[MPICH] MPICH2 1.0.6 inder Windows without DOMAIN

[madfran]

Hi,...

1) ok

2) With the cpi.exe found in the directory
   c:\Program Files\MPICH2\bin
   and specifying  1000000000 I see both processors working at 100%

3) Both
   I installed from msi and compiled under cygwin.
   It is a mistake ?
