[mpich-discuss] SGE & Hydra Problem

[Jayesh Krishna]

Hi,
 If you need to use SMPD you will need to recompile your code (AFAIK you won't need to recompile your code for other PMs).

Regards,
Jayesh

thanks for clarification - I wasn't aware of it. In the past I  
struggled a little bit with the different compilation methods of  
MPICH2 (mpd/smpd/smpd with rsh/gforker) and my conclusion was, they  
must always match the compilation of all involved parts.

BTW: will the other methods be dropped over time, when Hydra is the to  
be used one in the future?
