Introduction: Parallel computing may be defined as the simultaneous use of several processors to execute a computer program. There two types of parallel architectures  Shared memory multiprocessor(SMP)  Cluster Parallel Computer

Cluster: A cluster is simply a “stack” of processor machines usually mounted in a rack. The stack is configured such that one machine is designated the head node and a file server node to all the other machines. Client nodes technically known as slave nodes are connected, via an internal network

Figure 2: Example of Cluster Computer SUGAR cluster.

SUGAR CLUSTER: The Syracuse group has constructed a 320 CPU node parallel computer called the SUGAR cluster. It consists of  Head nodes: 6 Sun X2200-M2 computers, each containing two Dual-Core AMD Opteron 2.6 GHz processors  Compute nodes: Eighty servers each with one quad core Intel 2.4 GHz Xeon CPU and 8 Gb of RAM provide a total of 320 CPU cores and 640 Gb of RAM for the cluster  Cluster storage is provided by four file servers, each with 24 Tb of disk storage

The compute nodes and head nodes are connected via copper gigabit Ethernet (1000baseT)to a switch.

ALICE CLUSTER: a cluster of 64 dual-processor Pentium Pros running at 200 MHz All PCs are connected through a central Fast Ethernet switch In addition, there is a master node, a file server, and 4 development nodes.

Justification:  The three R’s:  Reuse.  Reduce.  Recycle.  Building of a computer by reusing the hardware components of the unused computers

Figure 4: Possible Configuration

Figure 5 : Possible Configuration

Methodology: 1. Survey and Collection of functional hardware and both software components from various sources. 2. Assembling of the components into a functional unit. 3. Designing a layout for the final product. 4. Loading of necessary Softwares. 5. Analysis and testing of the product.

Expected results: High Performance. Expandability. High Throughput. High Availability

Conclusion: It is certain that building a new computer by recyling the out of use hardware product, will invite lot of problems regarding the various issues that are related with the designing, implenting etc. But it is still encouraging to construct a working computer then not to use it all.
