== <center>'''INTRODUCTION OF HIGH PROCESSING CLUSTER'''</center>==

'''HPC cluster''' are used to run parallel programs for time-intensive computations and are of special interest to the scientific community. It commonly run simulations and other CPU-intensive programs that would take an inordinate amount of time to run on regular hardware.

Grid computing is a broad term that typically refers to a service-oriented architecture (SOA) with collaboration among loosely coupled systems. Cluster-based HPC is a special case of grid computing in which the nodes are tightly coupled.


==<center>'''REQUIREMENT OF BITS-PILANI'''</center>==

BITS had a requirement of High Processing Cluster for there applications .For this one slave node server with one master node server and Eight Slave node server with one master node server were used. RHEL5 server where installed in two node cluster and CENTOS5 server installed in 9 node cluster. 

All users authenticate via 389 ldap, IBM nodes handle Multi-master LDAP and other are LDAP Clients.

All users have home directories shared via NFS to other nodes. 

Around 10 Clients they have windows machines and 35 Clients have Sunray Terminals and need to implement VNC Enterprise Server 5.03 with LDAP Authentication for Windows .All terminals handle by Sunray Server software.

High Availability over NFS is implemented on IBM Machines.
