Checking GPU performance with Intel GPA
Hi, I have a challenge to check the perfomance of my application on Intel HD4000, nVidia and AMD GPU architectures. OpenCL code only. Is it possible to provide such tests with Intel GPA or I should use different tools for each platform? Thank you. Regards, Mikhail
Absolute timings
Hi. I'm not sure about the term (absolute) (I'm far from beeing fluent in English) I'm trying to optimize some GPU code, using GPA to test the results. Especially on a subset of the whole frame : [A] 1 quad (simple VS using VertexID to generate 3 vertices to draw a quad [using Scissor to render only the quad]) with some computations in PS (1 RT) [B] 1 rendering (dummy VS, complex GS [using PrimitiveID as input] reading the previous quad, simple PS rendering the generated triangles) I was surprised that each time I benchmark the code, GPA reported noticable timings differences.
Frame capture fails with "Invalid Parameters"
Hello,
I am having problems getting a frame capture with the version 2012 R3 (12.3.174307).
The HUD appears fine while the app is running but when I attempt a frame capture it says "Invalid Parameters" and "Capture Failed" underneath that. All of the tests (2x2 Texture, Simple Pixel Shader, etc) seem to work fine. Other applications seem to capture fine for me.
OS: Windows Server 2008 R2 SP1 64-bit
Video Card: Nvidia GeForce GTX 580 (8.17.13.142)
Thank you in advance for any help.
Draw Calls
Using the R3 version of GPA, is it possible to trace and record in a file Draw Calls through time as the graphical application I am testing is executing? My test system uses a Core i7 model 920 and an AMD/ATI HD 6990 in CrossfireX mode.
Can I get GPU load via an API call in my application?
Hi,
I'm looking for get the GPU load (MFX and EU loads) inside my C++ application.
So is here any way to use the "DirectTraceSample" or anay other DLL to have access to such measure.
Best regards.

Issues with GPA Monitor and ITT API
My studio has asked me to look at GPA for use in our automated testing pipeline. The use case we would like to implement is as follows:
Intel GPA cannot create frame capture file on Nvidia GTX460
I tried to analyze the rendering of Skyrim with intel GPA's frame
cpature(Ctrl+Shift+C),but i found it only worked in the starup menu,when
i entered the scene, it showed 'Unsupported D3DFORMAT: 0x5343564e', my
system is this:
OS:Win73 32bit
CPU:E8400
GPU:Nvidia GTX460
Error Log: [TAL][WIN pid=4084][ 90c] Unsupported D3DFORMAT: 0x5343564e
it was my first time to ues intel GPA ,does this tool work correctly with AIT or nvidia ' grapics card???
