GPA 3.0: System Analyser very slow on pause

Hi Folks,
I am pretty new to GPA, I am trying to use the platform view of the system analyser. I haven't added instrumentation to my game yet, but I wanted to get GPA up and running first. I can connect to my process correctly and see the various graphs properly (FPS / CPU utilization / etc). When I press pause on the application I see a blank "Capture status" box and nothing happens until about 5-10 mins. Any ideas about how to speed this up a little? Thanks for your help All the best, Ash PS. The forum editor lost all my formatting, weird.

Hello,

First of all, if you are not currently using Intel GPA Platform View, I would recommend that you disable trace collection -- first, use the "Configure Platform View" button, and then unselect the "Enable Tracing" option:

This should result in significantly faster operation for "pause".

If you were wanting to collect trace data and eventually use Intel GPA Platform View, the first thing I would recommend is to download the latest build of Intel GPA 3.0, build 111099 -- goto the Intel GPA Home Page for download info. [This latest build includes a number of updates for the Intel GPA Platform View feature.]

Regards,

Neal

Hi Neal,
Thanks for the reply, I didn't realise there were new builds of 3.0. I am trying to use platform view, so i'll give the new one a try. My build was 108906, so possibly a bit out of date. I will give it a go in the morning and let you know how I get on Thanks again, Ash

Hi Neal,

Yep, that made a lot of difference. It's still a bit hit and miss as to whether it will work or not. I need to restart the monitor and the System Analyser each time I want to profile. I guess it's still in beta. I don't seem to be getting any trace out. I added a few different"TAL_SCOPED_TASK_NAMED("myFunctionName");" calls. I expected them to appear in the TAL Watchdog or one of the threads, but I don't see anything. Any idea what I could be doing wrong. I will reread the docs.

*edit* Sorry, I had missed the fact that it had a linking error, I was testing a previously linked version.

Thanks for your help, All the best, Ash

Hello Ash,

I'm just checking up to see whether you've been able to make any additional progress in using Platform View -- please let us know what you think of the tool.

Regards,

Neal

Hi Neal,

Yep, It is a very useful tool for visualising what happens during a frame, something that other profilers can't do. I have definitely found some some bottlenecks that have directly come from using GPA. It is still a little unstable, but it will be a fantastic tool. As an independent game developer with little to no budget, the price is fantastic! I haven't been using it lately as I've got performance to an acceptable level at the minute, but I'm sure i'll be using it intensively again as my project nears release. I haven't even started using the GPU analyser part yet. Thanks for your help! Ash
