No progress reporting in ITK5

[lassoan (Andras Lasso)]

ITK5 is great for many reasons but users started to complain that 3D Slicer hangs because all they see that image processing filters are stuck at 0% (e.g., https://discourse.slicer.org/t/bilateral-filter-not-working/9797/9). It is really hard to use a filter if you don’t know that you have to wait seconds, minutes, or hours for it to complete.

I understand that progress reporting is harder since the new threading model is implemented in ITK but in interactive use cases progress reporting is essential. What would be the best way to get progress reporting working again?

I’ve found some posts related to a new “itkProgressTransformer” class, but it seems to be only used in a few classes and it is not clear how it can be applied to others. For example, I wanted to try it on itkMedianImageFilter, but there is no GenerateData method in this class. Is there any solution for such classes?

Thanks for bringing this up @lassoan. I’ve recently been working on some multi-threaded processing that takes a long time and I’d like to echo that the current situation is frustrating. With the default behaviour, progress sits at 0% until just before the end when all the threads finish, and then the 25%/50%/75% messages often show up simultaneously.

It would be great if this could be improved.

[dzenanz (Dženan Zukić)]

itk::ProgressTransformer maps progress from one scale to another, and is meant for use in mini-pipelines where filter has a pipeline of other files inside it.

One of the limitations is that progress reporting is only allowed from the “main” thread, to make sure it works well on all operating systems. And reporting at the end comes from here:

InsightSoftwareConsortium/ITK/blob/eb8ce3c6195b13878721ffc5475e1f32e183843a/Modules/Core/Common/src/itkPoolMultiThreader.cxx#L276-L284

Combined with the desire to avoid overhead associated with splitting image into more regions than necessary, it can end up with uselessly small number of progress updates.

Part of the reason to have multi-threaders report progress instead of filters, is that many filter authors did not bother with progress reporting. This came at the expense of important filters, which had their progress reporting frequency reduced with the use of default multi-threader.

Using TBBMultiThreader increases the frequency of progress updates, due to use of greater number of work units.

Reintroducing a per-pixel reporting would require redesigning ProgressReporter class in conjunction with ProcessObject, possibly relying on atomics. And then reinstating the use of ProgressReporter in filters of interest. A list of files which had it in ITKv4 is below. Good news is that per-filter effort would be small, because only a few filters had significant internal refactoring.

@dzenanz

Reintroducing a per-pixel reporting would require redesigning ProgressReporter class in conjunction with ProcessObject , possibly relying on atomics.

It would probably take me a day or two of sustained effort to do this, including reintroducing per-pixel reporting in a few filters to serve as examples of how to do it. In calendar time though, I should finish this before the beginning of February.

I guess this thread served as a good reminder for this, and while thinking about it I realized it would not be that hard.

[lassoan (Andras Lasso)]

Thanks a lot, this sounds good. Ideally, progress would be reported at regular time intervals (about once per second) and not regular percentage completion.

[blowekamp (Bradley Lowekamp)]

A couple items to thing about:

• Consider just creating a new ProgressReporter class the old one is still in use with the old threading model.
• Clearly if every thread is simultaneously updating the atomic progress, performance would suffer. Likely the progress reporter should update the atomic progress every so often, similar to when events occurred in the prior implementation.
• One of the oddities of the previous implementation was even though each thread computed progress, only the “calling/main” thread’s progress was reported, the others were ignored. I’m not sure if the new design should consider all threads progress, but if it does, the progress math will need to be changed.
• Computing progress on a per pixel basis was excessive, and some time a significant performance bottle neck for trivial filters. When converting filters to use the ScanlineIterator the progress was reported more sensible on a per scan line basis.

@dzenanz

One of the limitations is that progress reporting is only allowed from the “main” thread.

Just to clarify the requirement, the previous behavior was that all events were emit-ed by the thread originally executing the code not sub working threads. This needs to be clarified for cases when the user is executing multiple filters simultaneously, or when the ITK processing is already occurring in a “worker” thread.

An example of the later is the 3D Slicer filter “SimpleFilters” module where the execution occurs in a worker thread. Events received from ITK are placed on a queue for the main GUI thread to process.

This requirement is the trickle one, I’m curious what you plan for it.

progress would be reported at regular time intervals

That is a good idea and should not be hard, given that invoking the clock is not too slow:

Time to call steady_clock::now() 1 times : 1e-07 s
Time to call steady_clock::now() 100 times : 4.6e-06 s
Time to call steady_clock::now() 10000 times : 0.0004583 s
Time to call steady_clock::now() 1000000 times : 0.0448254 s
Time to call steady_clock::now() 100000000 times : 4.42698 s

Computed using:

#include <iostream>
#include <chrono>

std::chrono::steady_clock::time_point lastTime = std::chrono::steady_clock::now();

int
main()
{
  for (auto times = 1ull; times < 1000000000ull; times *= 100)
  {
    auto start = std::chrono::system_clock::now(); // record start time
    for (unsigned i = 0; i < times; i++)
    {
      lastTime = std::chrono::steady_clock::now();
    }
    auto end = std::chrono::system_clock::now(); // record end time

    std::chrono::duration<double> diff = end - start;
    std::cout << "Time to call steady_clock::now() " << times << " times : " << diff.count() << " s\n";
  }
}

I think that the ProgressReporter class can be updated in place, and kept being used with the old threading model.

@blowekamp

update the atomic progress every so often

I had the same thought.

@blowekamp

the new design should consider all threads progress

I was planning to. Yes, math will need to be changed.

I plan to record the invoking thread’s ID, similar to here, so I will only report progress from that thread.

[dzenanz (Dženan Zukić)]

I have a first stab at this in my fork. Master is currently at f24aacd. This compiles, but I haven’t tested it yet.

I plan to merge ExplicitProgressReporter into ProgressReporter via a different constructor. The existing constructor needs to be kept, because of allowing custom start point and progress weight. The new constructor would be made the default via overloading.

[dzenanz (Dženan Zukić)]

A pull request is ready for review now.

Here a second stab at adding the restoring the progress reporting:

Progress reporting revisionv5

@lassoan

Thanks a lot, this sounds good. Ideally, progress would be reported at regular time intervals (about once per second) and not regular percentage completion.

@lassoan Is this a hard requirement? Will just getting the old progress reporting be good enough? In thinking about this further, it makes more since for the application to poll the progress of the filter/pipeline than try to shoe horn in some pseudo time event queue into multiple location of ITK. With the new updates all threads will be constituting to the progress, so the progress will change even when the invoking thread is doing another task. Hence the application polling recommendation.

[lassoan (Andras Lasso)]

This is not a hard requirement at all. As long as we can get updates frequently enough (about up to 1-2 updates per second), it is good.

I mentioned the time-based reporting because this is what end-users ultimately need. Getting status updates at fixed percentage increments may result in unnecessarily frequent updates and may slow things down (if we run some quick processing 30 times per second then we might get thousands of status updates per second); or, if the total processing time is long, users may not get updates frequently enough.

[blowekamp (Bradley Lowekamp)]

There are certainly multiple solutions to these problems. And many of them are dependent on how an application is interacting with ITK and the events.

@lassoan

I mentioned the time-based reporting because this is what end-users ultimately need. Getting status updates at fixed percentage increments may result in unnecessarily frequent updates and may slow things down (if we run some quick processing 30 times per second then we might get thousands of status updates per second);

An alternative solution here on the application side is to suppress action for events if they are occurring too fast. The question that rises from this alternative approach is: Is the “slow down” occurring because ITK is slow at generating the events or is the application slow at executing an event?

I think the most robust solution for an application is to run ITK processing in a background worker thread, and have the application poll the process/pipeline for progress. ( I can easily update the SimpleFilters Slicer module to do this. )

Does VTK have this concept of “timed progress events”?

The ideal way to truly get time progress event emitted from ITK is to have an additional thread monitoring the progress and waiting for the time out to occur. This is clearly a more complex solution and not required for many usage of ITK, only certain applications.

Alternative implantation, can easily suppress too many events, but to effectively emit event at the requested interval there would be too much additional cost associated with checking the time elapsed frequently for slow processes.

[lassoan (Andras Lasso)]

It would simplify the application if ITK provided just the right amount of status updates, but I agree that things can be addressed at application level, that’s why it is not a hard requirement.

I don’t think VTK progress updates are time-based, but since VTK processings are typically for visualization, they ususally complete in a fraction of a second, so we rarely need progress updates at all.

Hello,
what’s the status of this? I see that https://github.com/InsightSoftwareConsortium/ITK/pull/1575 was merged. If I update to ITK 5.1rc3 do I magically get better progress reporting, or do I need to tweak some code? Have the examples/documentation been updated?
Thanks for working on this!

[lassoan (Andras Lasso)]

Yes, if you just use ITK (and don’t create your own ITK filters) then progress reporting now should work much better, without changing anything in your code.

[blowekamp (Bradley Lowekamp)]

Hello Tobias,

Upgrading to ITK 5.1rc3 will improve the progress reporting for ITK filters without you having to do anything.

The use of the TotalProgressReporter still needs be documented with perhaps some examples.

The progress reporting does improve all cases, however with the default configuration is has the least progress reporting. The default ITK configuration is with the PoolMultiThreader, and NumberOfWorkUnits = NumberOfThreads*4. The updated progress reporting works wonderful with the TBB threader, the PlatformMultiThreader and the PoolMultiThreader (when NumberOfWorkUnits == NumberOfThreads). There are a complicated number of options and behaviors here, but the current implementation has good performance, a clean API, and usage of the TotalProgressReporter easier than the prior ProgressReporter.

The PoolMultiThreader has ( what was to me ) surprising behavior with how the main or invoking thread only participates for one work unit, then stalls. There is still some work to do here.

[spinicist (Tobias Wood)]

Hello @blowekamp,

Sadly, I am that user, the one who is doing everything non-standard.

I have my own filter that overrides both GenerateData and DynamicThreadedGenerateData. Code is here: https://github.com/spinicist/QUIT/blob/mupa-mt/Source/Core/ModelFitFilter.h#L433 with the TotalProgressReporter on line 510 below.

I have tried as best I can to shoe-horn in the new progress reporting by looking at how you did it for other filters, but it’s not working yet. My current attempt prints:

Allocating output image memory
21:13:25 Processing...
21:13:25 Progress: 1% complete
21:13:25 Progress: 2% complete
21:13:25 Progress: 3% complete
21:13:25 Progress: 4% complete
21:13:25 Progress: 5% complete
21:13:25 Progress: 6% complete
21:13:25 Progress: 7% complete
21:13:25 Progress: 8% complete
21:13:25 Progress: 9% complete
21:13:25 Progress: 10% complete
21:13:25 Progress: 11% complete
21:13:25 Progress: 12% complete
21:13:25 Progress: 13% complete
21:13:25 Progress: 16% complete
21:13:25 Progress: 16% complete
21:13:34 Finished processing.

As far as I can tell, one thread is reporting the progress correctly, and the others are not reporting any progress. This particular problem is very unbalanced - that one thread is “processing” masked voxels and hence has nothing to do, so gets to 16% and finishes very quickly, while the others take a long time to finish and don’t report anything. Can you give me a couple of pointers?

I have also noticed the odd behaviour with PoolMultiThreader. Is this the place to discuss that or should we move that to another thread? I have resorted to calling my programs with (Number of Cores + 1) threads set as the maximum, otherwise I only utilise (Number of Cores - 1). That’s not ideal.

[blowekamp (Bradley Lowekamp)]

What is the output if you set the env variable ITK_GLOBAL_DEFAULT_THREADER=platform?

[dzenanz (Dženan Zukić)]

You could set number of work units to be equal to number of cores in your filter’s constructor, build ITK with TBB, or explicitly request platform multi threader (also in the filter’s constructor).

We could also fix pool multi-threader. One possibility is to create and expose ExecuteOneWorkUnit as a public method, which would be normally used by ThreadPool::ThreadExecute's loop. And when needed, also by PoolMultiThreader::SingleMethodExecute.

[spinicist (Tobias Wood)]

Hmmmm. This is a bit strange.

I have 6 real cores in my CPU (no hyper-threading).

ITK_GLOBAL_DEFAULT_THREADER=platform gives similar output before, but gets to Progress: 38% complete, for both 6 & 7 threads.

ITK_GLOBAL_DEFAULT_THREADER=pool gets to Progress: 38% complete, for both 6 threads, but only Progress: 16% complete for 7 threads.

I hope that’s clear, even if it makes little sense to me!?

Thanks for your help.
