Abstract
Tessellation is a manycore OS targeted at the resource
management challenges of emerging client devices, in-
cluding the need for real-time and QoS guarantees. It is
predicated on two central ideas: Space-Time Partition-
ing (STP) and Two-Level Scheduling. STP provides per-
formance isolation and strong partitioning of resources
among interacting software components, called Cells.
Two-Level Scheduling separates global decisions about
the allocation of resources to Cells from application-
specific scheduling of resources within Cells. We de-
