'''Core year:''' The equivalent of using 1 CPU core continuously for a full year. Using 12 cores for a month, or 365 cores for a single day are both equivalent to 1 core-year. Compute Canada compute allocations are based on core year allocations. | '''Core year:''' The equivalent of using 1 CPU core continuously for a full year.

'''Core equivalent:''' A core equivalent is a bundle made up of a single core and some amount of associated memory. In other words, a core equivalent is a core plus the amount of memory considered to be associated with each core on a given system.

'''Head or Login node:''' Typically when you access a cluster you are accessing a head node, or gateway/login node. A head node is configured to be the launching point for jobs running on the cluster. When you are told or asked to login or access a cluster, invariably you are being directed to log into the head node, often nothing more than a node configured to act as a middle point between the actual cluster and the outside network. | '''Head or Login node:''' Typically when you access a cluster you are accessing a head node, or gateway/login node.
