Hi, I have intel i7 3770K processor which has in built HD4000 graphics card. I also have a NVIDIA graphics card GTX650 Ti. I want to use intel media sdk to encode videos to H264 format. The problem is that the software encoder is taking too much CPU and i...
Hi, I'm trying to profile my application using the clGetEventProfilingInfo(). Rather than just looking at the kernel execution time (CL_PROFILING_COMMAND_END - CL_PROFILING_COMMAND_START) I'd like to know the absolute value of when the kernels were execut...
Hello,As the NDA seems to be over, I have few questions about HD4000 and OpenCL.I am testing performances of HD4000 embedded into IVB (i7 3720QM), with OpenCL GPU.
Hi seems even new 2012 macbooks with Ivy on Macos doesn't get OpenCL support for HD4000 graphics.. Is Intel working on that?
Can we use printf function with the GPU HD4000 ? or, is there is a solution to bypass this limitation ? it's for debugging , have you any better solution ? THX, Mohamed
Hello, I'm running OpenCL on Intel's HD4000 GPU. It seems that this GPU has no vector calculations. According to the query: CL_DEVICE_PREFERRED_VECTOR_WIDTH_FLOAT The vector width is 1. Which means that float4 calculations are executed as 4 float scalars.
I have a memory issue with the HD4000 GPU: I use a simple kernel that performs 2 simple operations, I run it over hundred of times (in a host loop), before each call I release all device and host buffers like this:
Hello, I would like to know whether the Mobile IGPs in the Ivy (hd4000) and haswell(4600) are able to output 1920x1080 at 120hz via displayports(either 1.1a or 1.2)? So far I have only been able to find the maximum resolutions at 60hz; however, nothing on...
This sample: http://www.opengl-tutorial.org/intermediate-tutorials/tutorial-16-shadow-mapping/ (Executable here: https://www.dropbox.com/s/zhytp394xmx6mpx/tutorial16_shadowmaps.rar ) Produces the attached result with weird red rendering on my HD4000 with ...
Seems OpenCL 2012 SDK doesn't support OpenCL on IVB GPU on Linux? it's right? must we wait for 2013 release? also seems intel is using a "GHAL3D" LLVM backend for OpenCL on GPU.. are you planning on open sourcing it similar to AMD open sourcing AMDIL back...
