==What resources are available?== <!--T:5-->
==What systems are available?== <!--T:5-->
Compute Canada is currently installing several million dollars’ worth of new computers while simultaneously retiring many old computers. During the transition period (2016-2018), a changing mix of old and new computers will be available to you. You can read about the progress of the migration from old to new systems [https://www.computecanada.ca/research-portal/accessing-resources/migration/ here].


===New resources (deployed in 2016 or after)=== <!--T:6-->
<!--T:6-->
Compute Canada began to renew its infrastructure in 2016. The first phase of the new deployment is composed of four new clusters, called [[CC-Cloud Resources|Arbutus]], [[Cedar]], [[Graham]], and [[Niagara]].
The renewal of the national infrastructure began in 2016. The deployment currently consists of five systems, called [[Cloud resources|Arbutus]], [[Béluga/en|Béluga]], [[Narval/en|Narval]], [[Cedar]], [[Graham]], and [[Niagara]].


<!--T:18-->
<!--T:18-->
[[CC-Cloud Resources|Arbutus]] (formerly known as GP1) is an extension of the West cloud. Arbutus went into service in September 2016.
[[Cloud resources|Arbutus]] is a [[cloud]] site, which allows users to launch and customize virtual machines. See [[Cloud]] for how to obtain access to Arbutus.


<!--T:19-->
<!--T:19-->
[[Cedar]] (GP2) and [[Graham]] (GP3) are general purpose clusters composed of a variety of nodes including large memory nodes and nodes with accelerators. They are expected to enter service in spring 2017.
[[Béluga/en|Béluga]], [[Cedar]], [[Narval/en|Narval]] and [[Graham]] are <b>general-purpose clusters</b> composed of a variety of nodes including large memory nodes and nodes with accelerators such as GPUs. You can log into any of these using [[SSH]]. A /home directory will be automatically created for you the first time you log in.

[[Niagara]] (LP) will be a large parallel cluster with nodes interconnected by a fast network.

===Legacy resources (deployed before 2016)=== <!--T:7-->
[https://www.computecanada.ca/research-portal/national-services/compute/ Computing] and [https://www.computecanada.ca/research-portal/national-services/storage/ storage] resources which were installed between 2004 and 2015 and are scheduled to be decommissioned in the next few years are referred to as ''legacy resources''. The legacy resources are administered by regional organizations, one of [http://www.ace-net.ca/ ACENET], [http://cac.queensu.ca/ the Centre for Advanced Computing], [http://www.calculquebec.ca/en/ Calcul Québec], [http://www.scinethpc.ca/ SciNet], [https://www.sharcnet.ca/my/front/ SHARCNET], and [https://www.westgrid.ca/ WestGrid]. To use a legacy resource you must have an account with one of these entities; you can apply for an account through [https://ccdb.computecanada.ca/me/facilities CCDB]. Resources deployed during and after 2016 will not require this step, nor will the two [[CC-Cloud|clouds]].
 
<!--T:8-->
Most [https://www.computecanada.ca/research-portal/national-services/compute/ legacy clusters] are classified as either capacity clusters or capability clusters. ''Capacity clusters'' contain nodes connected to each other by a relatively slow Ethernet network, while the ''capability clusters'' have a fast network, usually InfiniBand. Large parallel jobs will run better on capability clusters than capacity clusters, while smaller jobs will run almost anywhere.  


<!--T:9-->
<!--T:21-->
There are some specialty clusters among the legacy resources. Applications which require more than 512 GB of memory per node require ''large shared memory systems''. Compute Canada has four such systems:

For any other questions, you might try the Search box in the upper right corner of this page, the main page for our technical documentation or contact us by email.

What systems are available?

The renewal of the national infrastructure began in 2016. The deployment currently consists of five systems, called Arbutus, Béluga, Narval, Cedar, Graham, and Niagara.

Arbutus is a cloud site, which allows users to launch and customize virtual machines. See Cloud for how to obtain access to Arbutus.

Béluga, Cedar, Narval and Graham are general-purpose clusters composed of a variety of nodes including large memory nodes and nodes with accelerators such as GPUs. You can log into any of these using SSH. A /home directory will be automatically created for you the first time you log in.

Niagara is a homogeneous cluster designed for large parallel jobs (>1000 cores). To obtain access to Niagara, visit the Available Services page.

Your password to log in to all new national systems is the same one you use to log into CCDB. Your username will be displayed at the top of the page once you've logged in.

What training is available?

Most workshops are organized by the Alliance's regional partners; both online and in-person training opportunities exist on a wide variety of subjects and at different levels of sophistication. We invite you to consult the following regional training calendars and websites for more information,

One can also find a shared calendar of upcoming workshops.

What system should I use?

This question is hard to answer because of the range of needs we serve and the wide variety of resources we have available. If the descriptions above are insufficient, contact our technical support.

In order to identify the best resource to use, we may ask specific questions, such as:

  • What software do you want to use?
    • Does the software require a commercial license?
    • Can the software be used non-interactively? That is, can it be controlled from a file prepared prior to its execution rather than through the graphical interface?
    • Can it run on the Linux operating system?
  • How much memory, time, computing power, accelerators, storage, network bandwidth and so forth—are required by a typical job? Rough estimates are fine.
  • How frequently will you need to run this type of job?

You may know the answer to these questions or not. If you do not, our technical support team is there to help you find the answers. Then they will be able to direct you to the most appropriate resources for your needs.
