Radiant is a new private cloud computing service operated by NCSA for the benefit of NCSA and UI faculty and staff. Customers can purchase VM's, computing time in cores, storage of various types and public IP's for use with their VM's.
Radiant provides researchers a flexible, elastic, and scalable computing solution, using cloud-like virtualization, while remaining on-site at NCSA. Resource requests are made using NCSA's allocation management system and are reviewed on a weekly basis. Virtual machines can be as small as 1 vCPU with 2GB RAM up to a max of 32 vCPUs and 64GB RAM. Projects may be a single large VM, many small VMs, or any combination that meets your requirements. Each project will be encapsulated so that other users of the Radiant system will not be able to see, access, or disrupt machines running as part of your project. Using an interactive web interface or Openstack API, you can create new virtual machines that are based on available operating system images. You will be able to fully customize your virtual machines including the software and services they run. Virtual machines may optionally have publicly accessible network interfaces so that external users can access the resources provided by your systems. Radiant hosts provide 25Gb network links to the 100Gb cluster network and links to the NCSA WAN infrastructure at 100Gb. Radiant offers two pools of storage to meet different data storage needs; a high-performance, low-latency CEPH storage system built on enterprise SSDs, and a high-volume, bulk storage system available using NFS. Radiant will leverage future NCSA storage initiatives such as Taiga and Granite as they become available.
- 100 compute nodes each with:
- 2 x 12 core, Intel® Xeon® E5-2690 v3, 2.6GHz CPU with 256GB RAM
- Over 4000 virtual CPU's available for allocation
- 25TB aggregate memory
- 25GbE host/100GbE backing networking
- 265TB Usable flash storage capacity
Access to NCSA’s 10PB+ (and growing) center-wide file system (currently via NFS)
Requesting Resources or Starting a project
Requesting resources on Radiant is done through NCSA's resource management request portal (using the XSEDE Resource Allocation System). Access to the Resource portal requires and NCSA identity. If you do not already have one, please request one using the Identity Portal. Internal users will be asked to provide a University account number (CFOPA) for billing. External users should contact James Glasgow or Amy Schuele before submitting a resource request.
Information about Radiant allocations are in in the user documentation here. Submit your request using the form at:
Radiant resources can be purchased at government costing approved rates as detailed below. The minimum resource request is 1 VM with 2GB of RAM. Each VM is assigned 40GB of SSD storage for memory backing. Additional flash storage requests will be additional to the per VM base. Usage will be billed monthly and this is the shortest allocation period.
|Resource||Unit||Internal Rate||External Rate|
|Compute||1 vCPU + 2GiB RAM||$4.57||$7.25|
|Virtual Machine||1 VM + 40GB Flash||$4.97||$7.88|
|Public IP Address||1 IP address||$0.42||$0.67|
Public IP address space is lmited and restrictions may apply. NCSA security will monitor all public traffic. An explanation of internal and external users is here: OBFS
Example configuration pricing for an internal user:
1 VM with 8 CPUs,16GB of RAM, 1 public address, and 40GB + 100GB of flash storage
|Public IP Address||1||$0.42|
Questions or Need Help?
To put in a ticket for issues concerning Radiant please use the email firstname.lastname@example.org. It is very helpful when submitting requests to include your project name and any specific instance IDs that relate to your problem. Please note that Radiant admins will assist with any Openstack or Radiant problems, but may not be able to provide system administration advice or assist with issues specific to your host operations. Radiant is a standard Openstack environment and if you are stuck on something there are many resources available to you on the internet to solve your issues. You may also find help from other Radiant users in the #radiant-discussion Slack channel. Members of NCSA's software development team frequent the channel and have experience with operating complex systems on Radiant.
