CPU: Intel Pentium or above
10/100 Network Card (If your OSCAR server node is
going to be the router between a public network and
the cluster nodes, you will need a second network card)

Child Nodes
CPU: Intel Pentium or above
HD: 2GB or above
Network Card
All clients must have the same hardware architecture
Installing the Linux OS
Install Linux (RedHat 7.3)
Copy All RPMs from ALL of the OS
installation CDs (RedHat 7.3 have 3 CDs) to
the Hard Drive (/tftpboot/rpm)
Installing O.S.C.A.R.
Run the install cluster script with an
argument specifying your server’s
private network adapter.
./install_cluster eth0
Follow the documented procedures to
finish O.S.C.A.R. installation

over from scratch in order to recover
from irresolvable errors
the start_over script located in the
scripts subdirectory
Reboot the computer after running the
start_over script and reinstall from the
beginning

To compile, type: “mpicc hello.c –o
hello”
Start LAM environment, type “lamboot
bhost.def”
Run hello
To run program, type “mpirun C hello”
The output:
CHILD NODE: 1
CHILD NODE: 2
HEAD NODE
CHILD NODE: 4
CHILD NODE: 3
Output can and should vary.
