Which theoretical parallel model is closest to CUDA/OpenCL programming model?For example, it fits at some degree to the generic Parallel Random Access Machine (PRAM) model. However, that is too generic, since it makes abstraction of various memory access latencies and synchronization issues.My question is which is the theoretical model that CUDA architecture fits closest (having in mind the hierarchical parallelism of threads and blocks of threads that cooperate)?
Which theoretical parallel model is closest to CUDA?
parallel computing;machine models
To the best of my knowledge, it may be the Queuing Shared Memory (QSM) model, even though hierarchical parallelism of threads is not taken into account. However, accesses to local memory and global memory (different bandwidth), and bulk synchrony (in which threads can work asynchronously beetween barrier synchronizations) are considered.
