• RE: OpenCL time excetion increase in time

    Hi hterrolle,

    If each OpenCL kernel process the same amount of instruction/data, and you execute them directly one after the other, and the time increase at each kernel execution, it may be related to temperature of your device.

    Under Linux, if the device…

  • Opencl work group and G76 core

    Hi,

    I would like to ask whether a work group with 192 work items can run on multiple G76 cores?

    I thought similar as other GPUs, one work group can only run on one shader core. However, it seems not the case. 

    I got similar latency between a work group…

    How could it be so large?

    Most modern GPUs back buffers by system memory, so "it's just RAM".

  • Measuring performance of underlying OpenCL kernels in Arm Compute Library?

    Is there an easy way to measure performance of the underlying OpenCL kernels in the Arm Compute Library? Ideally, I'd like to use the OpenCL clGetEventProfilingInfo call.

  • Opencl Kernels overhead(queue time) in Mali-G72


    Hi,

    I am using OpenCL 2.0 in Mali-G72 based Android device and I am encountering a very large kernel queue/submit time overhead (CL_PROFILING_COMMAND_START - CL_PROFILING_COMMAND_QUEUED). it is sometimes 10X higher than the kernel execution time (CL_PROFILING_COMMAND_END…

    Mali SDK supporting compilation of Kernels written in C++ for OpenCL

    The Mali Software Development Kit (SDK) facilitates the development of OpenGL ES, Vulkan, or OpenCL applications for Mali-based platforms. While OpenGL and Vulkan are predominantly used for graphics, OpenCL provides ability to execute applications from…

  • Cache data invalidation between kernel calls in OpenCL

    Hello.

    Does L2 cache data invalidated after finishing each kernel invocation? If not the case, does invalidation depends on memory type (SVM, old buffers, mapped old buffers, etc)?

    Question related to Bifrost and Valhall architectures.
