[petsc-users] possible development on Windows?

[Alexander Grayver]

Hi Dominik,

I'm running Windows 7 Professional. I still use only local debugging 
(i.e. I run several MPI processes, but on the local machine), so I don't 
need Windows HPC. Since I work with IFC, it is a bit tricky for me and 
I'm not sure that you should follow same ugly way. What I do is to run 
several processes with mpiexec in suspended mode, then attach to them 
from VS Debugger and debug. With MPI Debugger installed you can easily 
switch among several processes. Using C/C++ you better first try to 
follow MS guidelines, e.g.:

Regards,
Alexander
