Introduction

● Cluster– A computer cluster consists of a set of

loosely connected or tightly connected computers that work together so that in many respects they can be viewed as a single system.

Data Intensive and Compute Intensive

● Data Intensive– Data-intensive computing is a class of parallel computing applications

which use a data parallel approach to processing large volumes of data typically terabytes or petabytes in size and typically referred to as big data.

● Compute Intensive– Compute-Intensive is a class of parallel computing applications where the

need for processing power is huge. Some applications without the use of clusters may take years on a single core personal computer to get the results.

What is the need for cluster ?

● To perform compute-intensive operations● Also if nodes in the clusters are used with Data-Intensive

environment like Hadoop, an optimal level of server usage can be achived.

● Clusters also can be used to serve compute services in the cloud– Ex: Installing Compute Services(Nova for openstack) on the cluster

Using Mosix Cluster in Virtual Environment● Download the VMDK file

– http://www.mosix.cs.huji.ac.il/mos2/mos2vm/VMOSIX-2.32.0.1-x86_64.vmdk.bz2

● Extract the file● Make the needful number of copies for the cluster● Change uuid for each VMDK file

– VBoxManage internalcommands sethduuid <file_path>

● Create new VM● Use VMDK file as SCSi storage

● Start VMs● Select one particular VM and form a cluster using

# cluster

● The cluster command will automatically detect all the nodes in the network and send the respective configuration to each system

● Any cluster application can be used with the help of mosrun command

List of Commands

● Basic commands– mosrun

– mosps

– mosmon

– mosmigrate

– moskillall
