Feedback: nice feature disappears in OpenCL Code Builder

Hi,

I have engaged in OpenCL development for three years.

Today I tried the new release OpenCL code builder.

It is disappointing somehow, for the following reason:

  1. Filling the information of performance session is boring. Every time when I need to change some parameters of my OpenCL app I need to fill it again, I think it will be beneficial to provide command line tools. Also, when right click the performance session I can not view or change its properties. if I have many session with different configurations to profile, then it is not feasible to do it in GUI anymore. In addition, I think the GUI should provide a box asking develop to name the session rather than a name with date by default.
  2. For the performance profiling results,  I can only profile host side profiling, but not the more interesting Kernel side profiling. For the two sub profiling options:
    1. "occupancy" , It showed me "You are using a shared context!" what does that mean? In my code only one context was created.
    2. "latency", crashed directly, show me my opition is incorrect  

      For the kernel profiling function, what I expected is something like GPU activity data, such as in Xtune,  then I could see how much GPU resources are utilized. Is there any tool now from Intel specilized for profiling OpenCL kernel performance on iGPU?

      Finally, following is my development setup.

      CPU: i5-4570R, OS: Win8.1, iGPU driver version 10.18.10.3960 (from device manager), OpenCL Code Builder Ultimate version. My code try to utilize iGPU (HD5200)

 Best,

Biao
