[mpich-discuss] Dual core problem

Hi,

I experimented with the smpd -d mode and it seems to be no problem to run
my projects in this mode.
I tried my program hello as well and it worked without errors.

But when I restarted smpd in normal mode the errors are there again.

So the solution for me is to use the smpd in debug mode (I do not know why
but it works).

See the attached outputs from

Thank you very much

BR,
Ladislav
