I am really new at this. I just loaded Scyld on my front end Machine and
got one slave node up using NodeBoot.img over network from the master
node. Eventually I will build a cluster. So I have a few question.
1) Was the Software that was on the master node installed onto the
2) Is it possible to login locally into a slave node? Because there is no
prompt for loging in on the slave node and for some reason I could not tell
into it from the master node.
3) I was trying to run a simple MPI program. And when I tried to run it
using the command /usr/mpi-beowulf/bin/mpirun -np 2 a.out I got the
following error message "p0_2813: p4_error: net_create_slave: host not
bproc node: -3 p4_error: latest msg from perror: Success. However, it did
work when I used 1 process instead of 2. Any ideas what
does this mean and what am I doing wrong.
If somebody could help me out I would greatly appreciate it.
