HSA queuing model (2015)
Book Chapter
Gaster, B., Howes, L., & Hower, D. (2015). HSA queuing model. In W. Hwu (Ed.), Heterogeneous System Architecture: Practical Applications for Industry. Morgan Kaufmann

HSA is a system architecture design for modern computing, integrating CPUs, GPUs, and other accelerators into a single shared memory system. To enable low-latency dispatch between different agents (devices) HSA provides architected queues, which enab... Read More about HSA queuing model.

HSA memory model (2015)
Book Chapter
Gaster, B., Howes, L., & Hower, D. (2015). HSA memory model. In W. Hwu (Ed.), Heterogeneous System Architecture: Practical Applications for Industry. Morgan Kaufmann

The HSA architecture has adopted a variant of the HRF-Relaxed memory model, which allows memory accesses to be controlled via fine grain scopes. This chapter introduces the HSA memory consistency model, how programmers can control memory visibility,... Read More about HSA memory model.

Heterogeneous-race-free memory models (2014)
Conference Proceeding
Hower, D. R., Hechtman, B. A., Beckmann, B. M., Gaster, B. R., Hill, M. D., Reinhardt, S. K., & Wood, D. A. (2014). Heterogeneous-race-free memory models. In Proceedings of the 19th international conference on Architectural support for programming languages and operating systems - ASPLOS '14. , (427-440). https://doi.org/10.1145/2541940.2541981

Commodity heterogeneous systems (e.g., integrated CPUs and GPUs), now support a unified, shared memory address space for all components. Because the latency of global communication in a heterogeneous system can be prohibitively high, heterogeneous sy... Read More about Heterogeneous-race-free memory models.
