All, I have a RedHat 7.2, kernel 2.4.9-31 cluster on 8 Athlon MP's. Recently added second 3c590 nic to bring up Channel Bonding. According to ifconfig -a my Bond0 is up. I can ping across without any packet loss. And can ftp internal to the cluster without any loss. But both the LAM and MPitch mpirun are broken. I can add servers with lamboot or pg4 but can not run mpirun. I get a network error. LAM and MPitch did work before "upgrade" to channel bonding. I have tried two separate Cisco switches and one Cisco switch running EtherChannel still does not work with MPIrun type programs. I have even tried recompiling Mpitch without any change in success. Any help would be appreciated.
