memory consistency modelsequential consistencyformal descriptionA novel memory consistency model for thousand-core processors is presented. The model simplifies cache coherence for the full chip, and reduces ca
Uniform Memory Consistency modelUnified FrameworkDistributed Shared Memory (DSM) is an architectural approach that allows processors to support a single shared address space that is implemented with physically distributed memory. The consistency model of a DSM system specifies the ordering constraints on ...
Memory consistency是一个架构"specification",规定了“ISA允许的正确行为”,而cache coherence是一个"means",是支持consistency以及保证shared memory程序正确运行的机制。 1.1 Consistency (a.k.a., memory consistency, memory consistency model, or memory model) Chapter 3: Sequential Consistency Chapter 4: Total ...

Thus, steering can be modeled as a case for DSM because all steering actions can be reduced to memory access operations. The consistency model used in a DSM system defines the order in which each process sees memory operations. This defines the value which a read operation must return. A ...
Among their other benefits, SVM atomics provide synchronization points to ensure that data is updated according to OpenCL’s memory consistency model. If SVM atomics are not supported, reads from the host and the device can still occur from the same region of the buffer, and updates can occur...

A sequence of mostly-independent commits (separable upon request) that fixes some typos, improves internal consistency, and takes better advantage of auto-linking to explain the memory model and the buffer/view operations that build upon it. gibson042 added the editorial change label Aug 16, 2024...
