A Beowulf cluster uses commodity computers networked together with shared libraries and programs to function as a single high-performance parallel computing system. It uses inexpensive personal computers running a Unix-like operating system with message passing software. The original Beowulf cluster was built in 1994 by NASA scientists to function like a single powerful computer through distributed processing across the networked nodes.
Cluster computing is a type of computing where a group of several computers are linked together, allowing the entire group of computers to behave as if it were a single entity. There are a wide variety of different reasons why people might use cluster computing for various computer tasks. It s also used to make sure that a computing system will always be available. It is unknown when this cluster computing concept was first developed, and several different organizations have claimed to have invented it.
Firewire (also called IEEE 1394) is another popular connector for adding peripherals to your computer. Firewire is most often used to connect digital camcorders, external hard drives, and other devices that can benefit from the high transfer rates (up to 480 Mbps) supported by the Firewire connection.

Simultaneously Leveraging Linux and Android in a GENIVI compliant IVI System – Andrew Patterson
It is widely accepted that Linux is the operating system of choice when building a complex, in-vehicle infotainment (IVI) system. The ability to support and quickly integrate device drivers for features such as CAN, MOST, graphics accelerators, networking interfaces, and Bluetooth can result in key differentiators for any GENIVI compliant IVI-based system. But what if Android was introduced as a second operating system? This session multiple implementations integrating both Android and Linux on multicore SoCs sharing audio and video resources across both domains while maintaining GENIVI compliance. Implementations with and without hypervisor technology will also be presented.
The encryption mechanism is a digital coding system dedicated to preserving the confidentiality and integrity of data. It is used for encoding plain text data into a protected and unreadable format.

This third part of Linux internals talks about Thread programming and using various synchronization mechanisms like mutex and semaphores. These constructs helps users to write efficient programs in Linux environment
In computing, ZFS is a combined file system and logical volume manager designed by Sun Microsystems, a subsidiary of Oracle Corporation. The features of ZFS include support for high storage capacities, integration of the concepts of file system and volume management, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, RAID-Z and native NFSv4 ACLs. Unlike traditional file systems, which reside on single devices and thus require a volume manager to use more than one device, ZFS file systems are built on top of virtual storage pools called zpools. A zpool is constructed of virtual devices (vdevs), which are themselves constructed of block devices: files, hard drive partitions, or entire drives, with the last being the recommended usage.[7] Thus, a vdev can be viewed as a group of hard drives. This means a zpool consists of one or more groups of drives.
In addition, pools can have hot spares to compensate for failing disks. In addition, ZFS supports both read and write caching, for which special devices can be used. Solid State Devices can be used for the L2ARC, or Level 2 ARC, speeding up read operations, while NVRAM buffered SLC memory can be boosted with supercapacitors to implement a fast, non-volatile write cache, improving synchronous writes. Finally, when mirroring, block devices can be grouped according to physical chassis, so that the filesystem can continue in the face of the failure of an entire chassis. Storage pool composition is not limited to similar devices but can consist of ad-hoc, heterogeneous collections of devices, which ZFS seamlessly pools together, subsequently doling out space to diverse file systems as needed. Arbitrary storage device types can be added to existing pools to expand their size at any time. The storage capacity of all vdevs is available to all of the file system instances in the zpool. A quota can be set to limit the amount of space a file system instance can occupy, and a reservation can be set to guarantee that space will be available to a file system instance.

High Performance Computing and the Opportunity with Cognitive TechnologyIBM Watson
With the ability to reduce “time to insight” and accelerate research breakthroughs by providing immense computational power, high performance computing is becoming increasingly important in the marketplace. Meanwhile, cognitive technology has risen to prominence, similarly accelerating new insight, but through a very different approach - by analyzing previously ignored unstructured data, which accounts for 80% of new data created today.
By combining the powerful computing power of the HPC market, along with the machine learning, natural language processing, and even computer vision techniques found within cognitive technology, there is a huge opportunity to accelerate breakthroughs and enable better decision making than ever before.

Small HPC clusters are widely used in many small labs since they are easy to build and cost-effective. When more power is needed, instead of adding costly new nodes to old clusters, we may try to make use of the idle times of some servers in the same building, that work independently for their own purposes, especially during the night. However such extension across a firewall raises not only some security
problem but also a load balancing problem caused by heterogeneity of the resulting system. In this paper,
we devise a method to solve such problems using only old techniques applicable to our old cluster systems
as is, without requiring any upgrade for hardware or software. We also discuss about how to deal with heterogeneity and load balancing in application, using a two-queue overflow queuing network problem as a sample problem.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

normally identical, commodity-grade computers
networked into a small local area network with
libraries and programs installed which allow
processing to be shared among them.
The result is a high-performance parallel
computing cluster from inexpensive personal
computer hardware.
Cluster means ,a group of similar objects growing
closely together.
3. The name Beowulf originally referred to a
specific computer built in 1994 by Thomas
Sterling and Donald Becker at NASA.
The name "Beowulf" comes from the main
character in the Old English epic
poem Beowulf.

5. There is no particular piece of software that
defines a cluster as a Beowulf.
Beowulf clusters normally run a Unix-
like operating system, such as BSD,Linux,
or Solaris, normally built from free and open
source software
6. Beowulf is a multi-computer architecture which
can be used for parallel computations.
Beowulf is a multi-computer architecture which
can be used for parallel computations.
It is a system built using commodity hardware
components, like any PC capable of running
a Unix-like operating system, with standard
Ethernet adapters,
7. Beowulf also uses commodity software like the FreeBSD,
Linux or Solaris , Knoppix operating system, Parallel
Virtual Machine (PVM) and Message Passing Interface (MPI).
The server node controls the whole cluster and serves files
to the client nodes. It is also the cluster's console
and gateway to the outside world
8. Unix is a multitasking, multi-user computer operating
system originally developed in 1969 by a group
of AT&T employees at Bell Labs, including Ken
Thompson, Dennis Ritchie, Brian Kernighan, Douglas
McIlroy, Michael Lesk and Joe Ossanna.
In 1974, UNIX was first licensed to an outside institution,
the University of Illinois at Urbana Champaign, by Greg
Chesson and Donald B. Gillies.
9. One of the main differences between Beowulf and
a Cluster of Workstations (COW) is that Beowulf behaves
more like a single machine rather than many workstations.
In most cases client nodes do not have keyboards or
monitors, and are accessed only via remote login or
possibly serial terminal.
Beowulf nodes can be thought of as a CPU + memory
package which can be plugged into the cluster, just like a
CPU or memory module can be plugged into a
motherboard.
10. The server node controls the whole cluster and serves files to the
client nodes. It is also the cluster's console and gateway to the
outside world.
Large Beowulf machines might have more than one server node,
and possibly other nodes dedicated to particular tasks, for
example consoles or monitoring stations.
In most cases client nodes in a Beowulf system are dumb, the
dumber the better.
Nodes are configured and controlled by the server node, and do
only what they are told to do. In a disk-less client configuration,
12. Beowulf is not a special software package, new network topology, or
the latest kernel hack.
Beowulf is a technology of clustering computers to form a parallel,
virtual supercomputer.
Although there are many software packages such as kernel
modifications, PVM and MPI libraries, and configuration tools which
make the Beowulf architecture faster, easier to configure, and much
more usable.
one can build a Beowulf class machine using a standard Linux
distribution without any additional software.
If you have two networked computers which share at least
the /home file system , and trust each other to execute remote
shells (rsh),
13. Clusters have a variety of different applications in
the world
They are used in bioinformatics to run DNA string
matching algorithms or to run protein folding
applications.
17. A cluster can be set up by using Knoppix
bootable CDs in combination
with OpenMosix.
The computers will automatically link
together, without need for complex
configurations, to form a Beowulf cluster
using all CPUs and RAM in the cluster
A Beowulf cluster is scalable to a nearly
unlimited number of computers, limited only
by the overhead of the network.
18. Provisioning of operating systems and other
software for a Beowulf Cluster can be
automated using software, Open Source
Cluster Application Resources (OSCAR) for
example. OSCAR installs on top of a standard
installation of a supported Linux distribution
on a cluster's head node.
