I have a problem with mpi in a 3-box cluster with machines named
node2 respectively. I install a newer version on
node2 and the problems arises. When I include only
node2 in the mpi ring, and try to boot with
head, I get the error:
mpdboot_head (handle_mpd_output 399): from mpd on node2, invalid port info: mpd_port=55270
When I try to boot from
node2, I get the error:
mpdboot_node2 (handle_mpd_output 426): from mpd on head, invalid port info: no_port
However, if I boot mpi with
mpd manually on
head and then add
node2 into the mpi ring, no errors are issued.
mpd can be boot without any error on
Is this some problems related to downward compatibility? How could I solve this?
Any hints will be highly appreciated. Thanks and Best Regards!
