When I use __local space qualifier, I couldn't debug inside kernel.
1. Is there anyone, who has same experience?
2. Is there any method to avoid this phenomena?
Hi, I have an OpenCL program of simulation that consists in a loop that launch 4 kernels per iteration. The execution can last hours.
I've launched this same application in Nvidia Fermi, ATI Radeon HD, Intel CPU X5650, Intel CPU E5... Now, I'm launching this application in Xeon Phi.
For the first time Intel® VTune™ Amplifier 2014 for Systems brings the most important, core capability of determining the hotspot in the C/C++ portion of your application to most Android* devices on Intel® processors (including rooted, not-rooted devices and with or without version compatible device drivers), such as those available at http://software.intel.com/en-us/android/get-device. This article will concentrate on the options required to make this work on non-rooted devices.
We are proud to announce that the Android Zone here on the Intel Developer Zone has been completely redesigned, with a focused, simple approach and a fully responsive design, so it looks great on every device. Check it out, and tell everyone you know who makes Android apps!
I found that reduction algorithm from NVidia SDK works on HD Graphics 4400 but don't work on Intel CPU i5.
I've expected that Nvidia algorithm works everywhere OR work only on Nvidia hardware so that difference in behavior between CPU and GPU on SAME machine looks strange for me.
Reduction algorithm and C# + OpenCL.NET unit test are in attachments. Unit test fails on Intel CPU with size = 4.
What differences in kernel execution exists between CPU and GPU? How can I fix the problem?
A question from newbie.
I am trying to use a reduction algorithm from NVidia SDK. It works correctly on Nvidia Discrete GPU, Intel HD Graphics 4400, but don't work on Intel CPU (Haswell i5).
