Re: AAE-9173 - Ran Out Of CPU Power
Yes, it has ALWAYS been this way. Live inputs that require minimal latency require heavier CPU usage. How big that gap is has a lot to do with how well your system is setup and configured. inefficient drivers, background processes-programs, misconfigured Bios, etc. will all limit how well your system will perform at low buffers/live inputs.

And it still falls short of explaining the erratic CPU spiking behavior, one example of which can be seen here... Clearly the capabilities of this system are being extraordinarily underutilized here. I am at a complete loss how anybody could view this as "normal" behavior. |

Re: AAE-9173 - Ran Out Of CPU Power
I really appreciate this discussion and the information shared. I think it's vital for both users, as well as for Avid to have a sampling of how their products are working, or not working, as intended. Of course it's frustrating for those who are having issues, and frustrating for those who can't relate to those same users. Nevertheless, I encourage a continuation of this conversation. While Avid hasn't historically enlightened the DUC, this community has generally helped each other out. More than once I've come across posts that have improved the stability of Pro Tools and my sessions.
Thank you to all participating. This is invaluable!

Thanks treason. FWIW, if there is a system out there that will run this session correctly (without the spiking behavior), I would very much like to know it's hardware configuration. To date, all systems across both platforms have done this so far, which really makes the issue a matter of a choice of workflow - using Aux busses for heavy-lifting processing like parallel compression, saturation, emulation etc - and funneling them down to a print track, which is very common nowadays in modern mixes. I think this is the reason the 9173 problem has been so difficult to pin down. It's not the hardware; it's the choice in workflow that seems to determine how soon that point of instability is reached. The test session is simply a way to magnify that bad behavior to bring it to the forefront and not be confused with other legitimate issues that might be at fault. |

Re: AAE-9173 - Ran Out Of CPU Power
The "spiking" will vary with the plugin selected and buffer size selected. Some plugins want more "time" with the cpu than other plugins. Those types of plugins will not work as well at lower buffer settings. Again, its always been this way. Any plugins known as "cpu heavy" are heavy BECAUSE they need more "time" with the CPU. When the HW Buffer is set low, the system (Pro Tools) is calling the cpu FAR more often in an attempt to reserve and take cycles that it can dedicate to latency. This is getting in the way of or "interrupting" other processes that are wanting more attention, like some plugins. Its why problematic drivers or drivers with heavy footprints like wireless drivers for instance will ALWAYS reduce system performance at these times and why bios settings that cause throttling and cpu fluctuations cause problems. Again, plugins and software determine the need, but overall system power and how well your system is optimized is the overall determining factor of the difference between high and low buffer settings with live inputs.

In case it might prove helpful to you, here's a summarized breakdown of where we're at so far... Quote:
"It's a test designed to highlight the problem in way that is impossible to ignore. The problem translates in a real working mix environment when a workflow involving some heavy processing on Aux tracks funneling down to a print track is used. This is a VERY COMMON style of workflow for MANY of us out there who do this for a living! Typically, however, it doesn't rear it's ugly head until a working session reaches around 65-70% in CPU usage. But when it does, it brings productivity to a GRINDING HALT with a CONSTANT slew of never-ending 9173 errors that can't be easily resolved because the only way to realy resolve them is to start disabling IMPORTANT AUX BUSSES." If you would genuinely like to help out, I (and I am sure many others) would like to know the EXACT hardware configuration for any system able to run those plugins on series-connected Aux busses in a manner that far exceeds the dismal results I'm seeing currently. A viable test result to confirm this would prove informative as well. Also, in a strange remark from Avid regarding the above case, they claimed that plugins on Aux busses should in fact be consuming FEWER CPU resources than ones on Audio tracks, contrary to what you've explained here. I'm not sure if he is mistaken about this or perhaps didn't understand the problem fully, but I'll update with any further responses as I get them. |

Re: AAE-9173 - Ran Out Of CPU Power
I was able to enable all plugs natively without spiking. Here are the screen shots and the Mac Info (also in my sig).

Question for you... I notice you're using an HDX system. All of the systems I've seen test results for outside of yours are Native systems. I don't recall for sure, but I seem to remember that newer HD licenses allow for Native operation as well - like for use on portable laptops and such. If that's the case, do you know if you might be able to conduct the same test in Native mode? (Obviously I'm trying to isolate whether this might be an HD vs Native issue) Or perhaps PCIe vs everything else? Last edited by wonder6oy; 10-20-2017 at 11:22 PM. |

This is a dedicated HDX system - thats all it does.

It can now be firmly established without question that this behavior is absolutely 100% NOT the intended behavior of the software, which for whatever reason has been difficult to prove up until now! |
