Mali OpenCL SDK allows executing opencl code on the Mali GPU.
Is it possible to execute OpenCL code on ARM CPU (Cortex-a7) using the Mali OpenCL SDK?
Not at present - ARM have only publicly released drivers that support OpenCL on Mali GPUs. However, a couple of months ago they passed conformance for OpenCL running on an ARM CPU, so one might expect that this will be possible in the future:
(from the Khronos conformant products page)
ARM Limited 2014-06-13 OpenCL_1_1
Linux 3.9.0 with ARM drivers on v7 CPU Compute Device Type: CL_DEVICE_TYPE_CPU
Compute Device Name: ARM Cortex-A15 NEON
Compute Device Version: OpenCL 1.1
Compute Device Driver Version: 1.1
Another option for running OpenCL on ARM CPUs is to use pocl, an open-source project.
