Memory Access Analysis
A LLVM based tool which can extract memory access pattern of global memory accesses from
OpenCL kernel code. A linear abstract representation is designed to describe the global memory
A Distributed Shared OpenCL Memory (DSOM) is designed in OpenCL runtime, which relieves users of having to manage data transfer explicitly among multiple devices. DSOM allocates
shared buffers in the system memory and treats the on-device memory as a software managed
virtual cache buffer. The management is based on the global memory access pattern.
OpenCL Performance Portability
Targeting on different computing devices with different architectures (CPU, GPU, MIC),
optimizations to improve performance of OpenCL programs are summarized. A performance
concerned code transformation (from fine-grained program to coarse-grained program) is being
