The CHPC Cloud System is a CentOS-based cloud computing infrastructure powered by Openstack and open source storage software Ceph. Openstack provide services like server virtualization, block & object storage systems, software defined networking, an image repository, a web based dashboard and authentication.You can read more about Openstack and its various projects.
The Centre for high performance Computing (CHPC) hosts an OpenStack cloud built on Supermicro server and storage systems, using the Supermicro TwinPro servers to provide 320cores/640threads (2.50 - 3.90GHz) and over 3TB DDR4 memory providing some 9GB RAM per core and all in just 4U of rack space. It is connected through Mellanox 100GB ethernet networking to Supermicro Ultra and Supermicro Simply Double Servers, providing a CEPH Storage cluster with over 1.5PB (1500TB) of mechanical disk storage and more than 220TB of flash storage, offering resources such as:
|CPU cores||Memory||Storage||Networking(Shared)||Object Storage (raw)||Block Storage|
|3452||78 TB||4.4 PB||10 Gbps||403 TB||403 TB|
Fees for using the CHPC cloud system
The cloud resources are allocated on per project basis, then several instances are provisioned based on the available resources allocated to the project. The billing is calculated by allocation not by percentage of utilization. The current billing fees are calculated as follows:
The Cloud is now open to a broader community of researchers. Apply today and start using our resources. A new project account creation on the Cloud user database can be requested through the application process. Upon acquiring cloud user account and submitting a project on our cloud user database, we will send you an email with further instructions.
Cloud users are expected to:

As an OpenStack cloud end user, you can provision your own resources within the limits set by cloud administrators.
The examples in this guide show you how to perform tasks by using the following methods:
As a cloud end user, you can use the OpenStack dashboard to provision your own resources within the limits set by administrators. You can modify the examples provided in this section to create other types and sizes of server instances.

Projects are organizational units in the cloud and are also known as tenants or accounts. Each user is a member of one or more projects. Within a project, a user creates and manages instances.
From the Project tab, you can view and manage the resources in a selected project, including instances and images. You can select the project from the drop-down menu at the top left. If the cloud supports multi-domain model, you can also select the domain from this menu.
