[MPICH] MPICH2 1.0.6 inder Windows without DOMAIN

[Jayesh Krishna]

Hi,
 You can compile MPICH2 on cygwin but then you have to make sure that you
use mpiexec/smpd compiled under cygwin. 
 We recommend users to install MPICH2 using the MSI installer and then run
programs compiled under cygwin (You can run programs compiled under cygwin
using mpiexec installed from the MSI package. Use the "-localroot" option
when running programs compiled under cygwin).

Regards,
Jayesh

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 ?
