The embedded world is so extremely flexible, because it is full of open standards. We therefore expect that big processor vendors will push harder than Google can push back. OpenCL-support is very important for GPGPU-libraries like ArrayFire, VexCL, ViennaCL – these…
Using async_work_group_copy() on 2D data
When copying data from global to local memory, you often see code like below (1D data): [raw] if (get_group_id(0)==0) { for (int i=0; i < N; i++) { data_local[i] = data_global[offset+i] } } mem_fence(CLK_LOCAL_MEM_FENCE); [/raw] This can be replaced this with…
Market Positioning of Graphics and Compute solutions
When compute became possible on GPUs, it was first presented as an extra feature and did not change much to the positioning of the products by AMD/ATI and Nvidia. NVidia started with positioning server-compute (described as “the GPU without a monitor-connector”),…
Valgrind suppression file for AMD64 on Linux
Valgrind is a great tool for finding possible memory leaks in code written in C, C++, Java, Perl, Python, assembly code, Fortran, Ada, etc. I use it to check out if the provided code is ok, before I start porting it…
