DCC/Live - Virtual linux cluster

Bootable CD-ROM

[ download ]

DCC/Live is a Knoppix based bootable CD-ROM which provides a virtual DCC cluster. The virtual cluster consists of one master-node (node0), and three virtual work-nodes running on User Mode Linux (node1, node2, node3). The network topology of the whole virtual cluster running on one PC can be seen on the figure below.

Check Debian Cluster Components homepage for more information about real DCC clusters, which this Live CD tries to simulate, mainly for educational purpouses.

Ways to use DCC/Live

Use DCC/Live to:

... learn parallel programming
... learn how clusters work
... learn how to configure and fine-tune the queueing system

QUICKSTART - run your first parallel program

1. Open a new shell, and change your working directory:

$ cd MPI_example

2. Compile the first example:

$ mpicc first.c -o first

3. Run your MPI program:

$ mpirun -np 3 -machinefile ./machines ./first

4. Run your program through the queueing system, requesting three nodes:

$ qsub -l nodes=3 first.PBS

5. Check DCC documentation:
README
FAQ
INSTALL (for real clusters)

Additionaly, if you are interested in details about TORQUE queueing system that is responsible for resource management within the cluster, check TORQUE admin manual.
