1. A method comprising: scanning, by a first processor in a work group, a memory associated with the first processor for data; updating, by the first processor, a first data structure to include at least a portion of the data based on the scanning, the first data structure comprising a plurality of entries that each include a first indicator that indicates whether a fraction of a page of memory is being referenced and a second indicator that indicates a size of a chunk of the contiguous memory representing the fraction of the page size when the second indicator is taken together with the first indicator; transmitting, by the first processor, a representation of the first data structure to one or more peer processors of the first processor included in the work group using a dedicated link; receiving, by the first processor, a representation of a second data structure comprising at least the first indicator and the second indicator associated with at least one of the one or more peer processors of the first processor; and updating, by the first processor, the first data structure based on the received representation of the second data structure.
