MOSIX Cluster allows connecting computers together to function as a single system for compute and data intensive applications. It can be used in a virtual environment by downloading a VMDK file, extracting it, copying it for each node, changing the UUID, creating VMs using the VMDK files, and running the "cluster" command on one node to automatically configure all nodes in the network to function as a cluster. Common MOSIX commands include mosrun to run programs on the cluster, mosps to view processes, and mosmon to monitor cluster status.

2. 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.

4. 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.

5. 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

6. 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

7. ● 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

8. List of Commands
● Basic commands
– mosrun
– mosps
– mosmon
– mosmigrate
– moskillall
