High Performance Computing
The terms High Performance Computing and Supercomputing are sometimes used interchangeably. High Performance Computing most generally refers to the practice of aggregating computing power in a way that delivers much higher performance than one could get out of a typical desktop computer or workstation in order to solve large scientific, engineering, or business problems.
List of HPC benefits are endless, but to mention just a few:
HPC is a great tool for research, development and innovation that leads to socio-economic impact in form of better solutions for societal challenges and increased industrial competitiveness in the region and international. The Zimbabwe HPC system shall be used in different domains by scientists, engineers, economists and others to solve complex problems and to acquire knowledge from simulations.

Its incomparable computing power exceeds the capabilities of ordinary personal computers and universal servers. If you are running applications that require high computational power and accuracy that cannot be done by an ordinary server computer our HPC system is your answer with its capability of running high-tech applications that can model and simulate complex situations.
Definitely HPC users’ needs to be trained by the Centre on how to access and run their specific application.
There are hundreds of examples of where HPC has been successfully used in industry, manufacturing, academia, public and private sector. In many industries it has become a well-established technology, whereas in others it is just starting to be used. Just a few examples are given below:
- Airbus views HPC as an essential technology. Design of the A380 would have been impossible without HPC to simulate airflow over the structure and the combustion processes in the engines.
- HPC numerical simulation is recognized at Électricité de France (EDF) as an indispensable tool. It has been used for a long time in such important operational matters as optimizing day-to-day production, or choosing the safest and most effective configurations for nuclear refueling. However most of the advances towards higher levels of performance have been driven by the constant need to explain complex physical phenomena behind maintenance issues better, to assess the impact of potential modifications or new vendor technology and to anticipate changes in operating or regulatory conditions.
- Formula 1 racing teams such as Renault use HPC to optimize the design of their cars using aerodynamic simulations.
There is a simple reason why waiting for a faster PC to run your code may not be the wisest option. Firstly it might allow competitors to overtake you. HPC could be seen as the way to get that faster computer today rather than in a year’s time. It might cost a competitor more to invest in HPC, but if they do so and take your market share, you might end up the big loser. Furthermore, it is no longer clear that desktop systems will really make many applications run faster year on year. The multi-core systems which are now ubiquitous will not necessarily make an individual application run faster.
The term cloud computing has been in use now for a few years. Basically it’s a model for how you can access computing facilities, rather than being about the technologies themselves. In the cloud paradigm you buy the computing as service, rather than owning and maintaining your own systems. The main attraction to the user is that it might be (but is not guaranteed to be) lower cost and the drawback is that you have less control of the resources and less ability to specify what you want.
The user must make an application to the HPC Centre.
The system is deployed via Virtual Private Network (VPN) for remote users hence a user needs to establish a remote network connection. The system can also be accessed by users who can physically visit and connect at the Centre through Local Area Network connection.
There is a minimum usage cost.
Web Hosting
In Shared Web Hosting, multiple clients are hosted on a single server i.e. the clients share the server's resources. This helps reduce the cost, since the cost of the server and its resources are spread over all the clients/packages hosted on the server. Shared Hosting is perfect for personal websites, small and mid-sized businesses that do not require all the resources of a server.
Yes! Our Pro and Business shared hosting plans allow you to host more than one Website, by adding secondary domains through your hosting control panel i.e. cPanel.
Yes, all our Hosting packages come with Unlimited Email Hosting.
Yes, you can easily upgrade to one of our higher plans at any time.
Yes, your data is a 100% secure and is backed-up every 5 days.
Yes, all our servers are protected by Clam AV.
While a Shared Hosting package cannot be used for this purpose, you can easily resell custom packages with our Reseller Hosting. To view our Reseller Hosting plans, click here.
Yes, we provide SSH access to your domain. Because this is a shared environment, you will not get root access. However, you will be able to achieve most of your requirements by having the rights to access only the files relevant to your domain.
Our Support team is always at hand to assist you. You can take a look at all our contact details here.
Servers
The server uplink port speed is up to 1 Gbps.
After the payment, your server will be provisioned in about 30 minutes and you can access it via SSH. The disk resize operation, however, may still run in the background for a while after provisioning.
You are responsible for your backups and web content. It is recommended that you keep copies of your content safe and make your own backups. You can take a backup from your cPanel or use a remote backup solution.
To ensure high uptime and accessibility at all times, we are available 24x7 for any hardware, network, booting, O.S. or login issues. Our System Administration Support will also assist you with basic cPanel & Firewall setup and their issues.
At present, the additional storage feature is only available with our HDD servers in the US data centre.
Would love to hear about such new features requests to help us serve you better.
Dedicated Servers can be used for Websites, Databases, Custom Applications, Ecommerce, DNS, File Storage and Emails. Emails, however, must be restricted to personal, organisational or professional purposes. The use of Dedicated Servers to send out mass emails/marketing is NOT recommended and can attract penalties.
Our Dedicated Servers are virtualised (1:1). Thus, nested virtualisation will not work due to network restrictions on the host system.
We don’t have any backup solution at the moment. Yet, we strongly recommend that you maintain a remote backup to avoid any hassles during any ill-fated incident.
SSL Certificate
An SSL (Secure Sockets Layer) Certificate is a digital certificate that verifies the identity of your website and encrypts information sent to and from your website.
An SSL encrypts your customers' sensitive information such as their identity, personal address, debit/credit card details, password, etc. by encrypting the data from their computer to your web server.
Yes, Comodo SSL Certificates are compatible with all major browsers.
After purchase of SSL Certificate, you need to complete the verification process with the certificate authority. To apply for an SSL, kindly follow the steps mentioned here.
You need to generate a CSR from your control panel by providing your website and organization details.
After your certificate has been issued, it will be available in your control panel. In order to install the certificate
You would need to reissue the certificate if the organization details need to be updated.
At the moment, you cannot upgrade/downgrade the certificate.
