- Additional information
- This work studies the language-level memory models of the 2011 revision of the C programming language and the OpenCL 2.0 programming language, via rigorous mathematical modelling. It shows how to drastically simplify the way sequentially-consistent atomic operations are treated and reveals a number of memory model deficiencies and ambiguities. The work informed the Khronos Group and the HSA Foundation in the design of the OpenCL and HSA memory models, respectively (contact: FoEREF@ic.ac.uk). Follow-on work at POPL'17 (https://dl.acm.org/citation.cfm?id=3009857) informed the design of the Vulkan memory model (contact: FoEREF@ic.ac.uk). POPL’16 acceptance rate: 23.4%/252.
