Hi, Mike
With 192.168.1.*, we could only access the tree network. In order to use
the torus network, we need to use the 12.x.y.z+1 ip address. (x, y, z
here is the coordinates of the compute nodes).
The code below could bring the torus ip address up.
IP=""
set_torus_ip()
{
x=$1
y=$2
z=$3
z=`expr $3 + 1`
ifconfig eth1 12.$x.$y.$z netmask 255.0.0.0 mtu 8996 -arp
IP=12.$x.$y.$z
}
BG_PSETORG=`cat /proc/personality.sh | grep BG_PSETORG | cut -d '"' -f 2`
echo ${BG_PSETORG} >> /dev/shm/localip
set_torus_ip $BG_PSETORG
best
