ARM Mali support OpenCL GPU phone, now on the market is still relatively small (beginning in the second half, with the new mobile phone listing, the 6 series GPU listing, this situation will change), according to my current situation, just listed Huawei Glory 6 is Mali T628. There is no test, do not know whether the system comes with the OpenCL library. However, I also tried to download the OpenCL SDK to compile the OpenCL library (please click here).

As for the Vivante GPU, the official website is said to support OpenCL, the use of its GPU mobile phone is too few, currently I only know Huawei's K3v2 chip, but in the Huawei P6 test results system does not come with the OpenCL library. I did not toss the SDK of Vivante GPU, so the specifics are not very clear.

PS: Compared to rendscript and OpenCL with Gaussian filtering on my phone, renderscript is much slower than OpenCL with the same strategy. In terms of performance, the Rendscript scheme was abandoned.
