[mpich-discuss] 答复: how to connect MPI_Send with CH3_isend

[yaohui]

Thank you very much!
	Finally I got a response!
I am doing some researches on adding HT(HyperTransport) into mpich2,I am
just wandering when we configure the mpich2 with 
			./configure ¨Cwith-device=ch3:sock (ch3:nemesis)
that means we definitely select one network as the channel to communicate,
but if there are any possibilities that you can dynamic 
control the network we use ,sometimes messages go through Ethernet,
sometimes go through IB. could you give me some materials 
to understand what's the difference between ~/ch3/channel/sock
,~/ch3/channel/sctp ~,~/ch3/channel/nemesis/nemesis/net_mod/tcp_module
, ~/ch3/channel/nemesis/nemesis/net_mod/sctp_module,
~/ch3/channel/nemesis/nemesis/net_mod/ib_module
 
Thank you again!
 
Best Wishes!

The best way to understand what happens is to step through the calls
with a debugger.  The channel is selected in the configure step, and
only that channel will be compiled, so there will be only one copy of
ch3_isend in the binary.
