Abstract
The ongoing trend to more heterogeneity forces us to rethink the design of systems. In this talk, I will present a new system design that considers heterogeneous compute units (general-purpose cores with different instruction sets, DSPs, FPGAs, fixed-function accelerators, etc.) from the beginning instead of as an afterthought. The goal is to treat all compute units (CUs) as first-class citizens, enabling 1) isolation and secure communication between all types of CUs, 2) a direct interaction of all CUs to remove the conventional CPU from the critical path, and 3) access to OS services such as file systems and network stacks for all CUs.
To study this system design, I am using a hardware/software co-design based on two key ideas: 1) introduce a new hardware component next to each CU used by the OS as the CUs' common interface and 2) let the OS kernel control applications remotely from a different CU. In my talk, I will show how this approach allows to support arbitrary CUs as aforementioned first-class citizens, ranging from fixed-function accelerators to complex general-purpose cores.
