BUILDING of 3 R'sCLUSTER PARALLEL COMPUTER

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 

Figure 1: 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

Literature ReviewBewulf Cluster Project: was started at the

Center of Excellence in Space Data and Information Sciences NASA in early 1994.

Hardware Configuration specification:One Master Node: Two Pentium III 1GHz CPU, 512M RAM, three

3Com 3c905c Ethernet cards, one 30G bytes hard disk, one floppy, one VGA card, one monitor

One NFS and NFS Root Server Node: Two Pentium III 1GHz CPU, 512M RAM, two 3Com

3c905c Ethernet cards, one 30G bytes hard disk, one floppy, one VGA card, one monitor

11 Client Nodes: One Pentium III 1GHz CPU, 512M RAM, two 3Com

3c905c Ethernet cards, no hard disk, one floppy, one VGA cards (for debugging)

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 MHzAll PCs are connected through a central

Fast Ethernet switchIn 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.
