[mpich-discuss] dllchan and Nemesis MX?

[Scott Atchley]

Hi all,

Does dllchan support ch3:nemesis:mx?

Also, the README states:

> To select a channel other than the default channel, set the environment variable MPICH_CH3CHANNEL to the channel name (i.e., sock, shm, or ssm).

Does this mean that you cannot use combinations (e.g. sock and shm or mx and shm)? I cannot imagine someone wanting to use MX with sock, but someone might want to try mx with shm to see if there is any performance difference.

Thanks,

Scott
