You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 44.214.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 16:45, 10 January 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''Techila Distributed Computing Engine''' (earlier known as '''Techila Grid''') is a commercial [[grid computing]] software product. It speeds up simulation, analysis and other computational applications by enabling scalability across the IT resources in user's on-premises data center and in the user's own cloud account. Techila Distributed Computing Engine is developed and licensed by Techila Technologies Ltd, a privately held company headquartered in [[Tampere, Finland]]. The product is also available as an on-demand solution in Google Cloud Launcher, the online marketplace created and operated by [[Google]]. According to [[International Data Corporation|IDC]],<ref>((cite book|last=Wu|first=Jie|title=The Rise of Grid-Based High-Performance Computing: A Cost-Effective Approach to HPC Acquisition|year=2010|publisher=IDC|pages=7|url=http://idcdocserv.com/941))</ref> the solution enables organizations to create HPC infrastructure without the major capital investments and operating expenses required by new HPC hardware.

==Product features==
Techila Distributed Computing Engine is a [[distributed computing]] [[middleware]] and management solution, which can be used to access and manage on-premises and cloud IT resources for various [[high-performance computing]] (HPC) computing uses, including [[high-throughput computing]] (HTC) scenarios. It creates a scalable computing service and execution environment that can also support applications that are deployed within production environments.

The technology of Techila Distributed Computing Engine is built on an [[autonomic computing]] architecture that is patented by Techila Technologies. This has enabled features such as automated system management and fault tolerance, which simplify the deployment, use and administration of large-scale distributed computing systems.

==Architecture==
===Techila Server===
'''Techila Server''' is a [[Java (programming language)|Java-based]] software product, which optimizes the performance of a Techila Distributed Computing Engine environment and the jobs in it. The optimization done by Techila Server supports not only large jobs, but also makes the system suitable for running small computational jobs. The performance of Techila Distributed Computing Engine in different scenarios was evaluated in a thesis at [[Tampere University of Technology]].<ref>((cite book|last=Koskinen|first=Marko|title=Evaluating the performance of job management systems in different distributed computing environments|year=2010|publisher=Tampere University of Technology|pages=63|url=http://www.techilatechnologies.com/wp-content/uploads/2010/07/Sun_Grid_Engine_vs_Techila_Grid.pdf))</ref>

Originally, the Techila Server was delivered as an embedded appliance. The embedded appliance product was discontinued in 2012. Currently, Techila Server is delivered either as a [[virtual appliance]] or using cloud-specific deployment tools.

===Techila Worker===
'''Techila Worker''' is the [[software agent]] that must be installed on each computer that will participate in a Techila Distributed Computing Engine environment. The computers can be physical, or they can be [[Virtual machine|virtualized]] computers running on a [[hypervisor]] or in a cloud virtual machine. Techila Distributed Computing Engine supports following public cloud services: [[Microsoft Azure]], [[Amazon ec2]] and [[Google Compute Engine]]. Once the Techila Worker software is installed on a computer, it will authenticate the computer to the Techila Server using a certificate, and the system will use [[Self-management (computer science)|self-management]] to automatically configure the computer to run jobs received from the Techila Server.

Techila Worker is a [[Java (programming language)|Java-based]] client middleware component that can be run on Microsoft Windows or Linux. Because of this, the client computers participating in the Techila Distributed Computing Engine system can have different hardware and software platforms. Techila Worker software runs on the lowest possible priority on the computer. The Techila Worker is also interoperable with batch-queuing systems, like the [[Simple Linux Utility for Resource Management|SLURM]], [[TORQUE]], or [[Oracle Grid Engine]] (previously known as Sun Grid Engine, SGE). This interoperability allows existing HPC users to use their existing infrastructures as a part of a Techila Distributed Computing Engine system without the Techila Worker interfering with the other system.

===Techila SDK===
'''Techila SDK''' (earlier known as Techila Grid Management Kit or Techila GMK) is a library of software components that connect applications to the Techila Distributed Computing Engine environment. The SDK includes plug-ins for many commonly used research and development tools and languages, such as [[MATLAB]], [[R (programming language)|R]], [[Python (programming language)|Python]], [[Perl]], [[Java (programming language)|Java]],  [[C Sharp (programming language)|C#]]/ [[.NET Framework|.NET]] [[C Language|C]]/ [[C++]], [[FORTRAN]], and [[Command-line interface]] script. The applications that have been developed using [[application programming interface]]s in the Techila SDK can also be deployed within production environments and run as service in a SOA environment. Techila SDK supports both Windows and Linux operating systems.

===Administrator User Interface===
A web-based '''Administrator User Interface''' provides administrators with a simplified and easy-to-use interface to the Techila Server. The Administrator User Interface allows monitoring system activity, view and control job execution, execution policy, monitor and control Techila Workers and Techila Worker Groups, control security settings, and manage users.

==History==
Techila Distributed Computing Engine technology started initially from the vision of grid computing and enablement of fast simulation and analysis without the complexity of traditional high-performance computing.

The security of Techila Distributed Computing Engine was evaluated by Nixu Ltd in 2008. After this, Techila Distributed Computing Engine has been accepted by security-sensitive industry sectors, such as Finance and Insurance, Engineering and Pharmaceutical.

Techila Distributed Computing Engine was demonstrated by a research team at the [[University of Helsinki]] in 2011 as being capable of providing autonomic management to computing environments of large numbers of [[Azure Services Platform|Windows Azure]] cloud instances. The University of Helsinki has also demonstrated Techila Distributed Computing Engine's ability to enhance the usability and utilization of large-scale cluster resources in projects implemented using [[MATLAB]], [[R (programming language)|R]], [[Python (programming language)|Python]], [[Java (programming language)|Java]], and [[C Language|C]]/ [[C++]]/ [[C Sharp (programming language)|C#]].

In a Techila Distributed Computing Engine system, computational resources can be arranged into device groups for organizational, security, compliance, and administrative control. Despite its performance in large-scale systems such as CSC - IT Center For Science, it is also suitable for smaller environments such as the TUTGrid] which utilizes the idle capacity of desktop PCs and other computers at [[Tampere University of Technology|Tampere University of Technology (TUT)]] for scientific computing.
