 ==What resources are available?==
-===New resources (deployed in 2016 or after)===
+Compute Canada began to renew its infrastructure in 2016. The new deployment is composed of five new clusters, called [[Cloud resources|Arbutus]], [[Béluga/en|Béluga]], [[Narval/en|Narval]], [[Cedar]], [[Graham]], and [[Niagara]].
-Compute Canada began to renew its infrastructure in 2016. The new deployment is composed of five new clusters, called [[Cloud resources|Arbutus]], [[Béluga/en|Béluga]], [[Cedar]], [[Graham]], and [[Niagara]].
 [[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.
-[[Béluga/en|Béluga]], [[Cedar]] and [[Graham]] are '''general purpose clusters''' composed of a variety of nodes including large memory nodes and nodes with accelerators.  You can log in to any of these using [[SSH]] and the same password you use at ccdb.computecanada.ca. A home directory will be automatically created for you the first time you log in.
+[[Béluga/en|Béluga]], [[Cedar]], [[Narval/en|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 in to 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 [https://ccdb.computecanada.ca/services/opt_in Available Services] page.
 Your '''password''' to log in to all new national systems are the same one you use to log in to [https://ccdb.computecanada.ca/ ccdb.computecanada.ca]. Your '''username''' will be displayed at the top of your home page at [https://ccdb.computecanada.ca/ ccdb.computecanada.ca] once you've logged in there.
-===Legacy resources (deployed before 2016)===
-Computing and storage resources which were installed between 2004 and 2015 and 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]].
-Most 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.
-There is one legacy cluster equipped with accelerators such as [https://en.wikipedia.org/wiki/General-purpose_computing_on_graphics_processing_units GPUs]. You will find them on the following legacy system:
-* Helios, hosted by Calcul Québec and equipped with NVidia GPUs.
 ==What resources should I use?==
-This question is hard to answer because of the range of needs Compute Canada serves, and because of the enormous variety of resources we have available --- especially during the 2016-2018 renewal period. If the descriptions above are insufficient, contact Compute Canada’s [[technical support]] or your [https://www.computecanada.ca/about/partners/ regional support].

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