[MPICH] Development Queries

[devesh sharma]

Hi everybody,

I have some queries regarding the developement of CH3 device-

1)  In the implementation of ssm channel what is the significance of
'businesscard' and why it is used?

2 ) How ssm channel comes to know whether to Shared memory OR
underling high speed interconnect? Which part of MPICH2 is responsible
for this decision?

Thanks
