GPU Tests - pixel crashes on GPU Hilton #34659

tsusa · 2021-07-27T22:16:09Z

Following a crash mentioned in [1], slide 5, we run

It crashes at [2] (&inputDataWrapped is != 0 at that point) with an error

@tsusa

Following a crash mentioned in [1], slide 5

Is this the CMSONS-13106? (I'm not authorized to view that ticket)

Is the error fully reproducible? (I guess so but want to make sure)

The

terminate called after throwing an instance of 'std::runtime_error'

tells that there are likely two exceptions in flight (which leads to call to terminate(); could tell better with fuller log), and the printed out what() is from the second exception, while the first exception would be more interesting. A way to get handle on that would be along

$ gdb cmsRun
> catch throw
> run step3_...py
wait
> bt # to show the stack trace of the exception; hoping that there are no other silently swallowed exceptions being thrown before

On the other hand, given the CUDA error message cudaErrorIllegalAddress: an illegal memory access was encountered I don't have high hopes for the first exception to tell us much. If it is a CUDA error, the error message is likely the same (i.e. some kernel accessed invalid device memory).

Given the statement of "data without pixel" on the slides, I'd concur with @slava77 (#34659 (comment)) that some protection is missing. I wonder what the printout

cmssw/RecoLocalTracker/SiPixelRecHits/plugins/SiPixelRecHitFromCUDA.cc

Lines 73 to 77 in 23f1aad

    
           auto const& inputData = ctx.get(inputDataWrapped); 
        
           nHits_ = inputData.nHits(); 
        
           LogDebug("SiPixelRecHitFromCUDA") << "converting " << nHits_ << " Hits";

would say.

based on https://cmsoms.cern.ch/cms/runs/report?cms_run=343762&cms_run_sequence=GLOBAL-RUN
the pixel FEDs are not included

The

terminate called after throwing an instance of 'std::runtime_error'

tells that there are likely two exceptions in flight (which leads to call to terminate(); could tell better with fuller log), and the printed out what() is from the second exception, while the first exception would be more interesting.

Just to add explicitly, I will improve this part of cms::cuda::ScopedContext during the fall (#30266) so that we could avoid the second exception in such cases.

Two additional tests were done:

step3 was repeated with the filter used to remove the pixel FEDs, as done in Pixel Local GPU reco crashes on missing detector input (no Pixel FED) #34496 -> crashes with the same error
step3 was repeated with the last 12_0_X IB (CMSSW_12_0_X_2021-07-27-2300) -> works fine. [1] correctly prints that number of hits is 0.

makortel · 2021-07-28T19:48:25Z

The log and the gdb look a bit different than I expected, so I'm taking a look (I'm also able to reproduce).

step3 was repeated with the last 12_0_X IB (CMSSW_12_0_X_2021-07-27-2300) -> works fine. [1] correctly prints that number of hits is 0.

This observation makes me wonder if 11_3_3 could be missing some pixel development that is in 12_0_X that could make a difference?

makortel · 2021-07-28T20:06:25Z

I added a cudaDeviceSynchronize() to the beginning of SiPixelRecHitFromCUDA::produce() (and set a breakpoint in gdb early to prevent the construction of cms::cuda::ScopedContextAcquire for its destructor to not to terminate the program), and already the cudaDeviceSynchronize() reports cudaErrorIllegalAddress: an illegal memory access was encountered.

makortel · 2021-07-28T20:12:49Z

Current Modules:

Module: CAHitNtupletCUDA:pixelTracksCUDA (crashed)
Module: none

This is awfully similar to cms-patatrack#306 (and cms-patatrack/pixeltrack-standalone#188), but with already single process run with single EDM stream.

makortel · 2021-07-28T20:33:49Z

CAHitNtupletGeneratorOnGPU::makeTuplesAsync() does not have a check for zero hits. Adding one (similar to the one in makeTuples()) right after constructing tracks allowed the job to complete processing the event.

On makeTuples(), maybe it would make sense to move the check

cmssw/RecoPixelVertexing/PixelTriplets/plugins/CAHitNtupletGeneratorOnGPU.cc

Lines 231 to 232 in bec73cc

    
           if (0 == hits_d.nHits()) 
        
             return tracks;

earlier, right after

cmssw/RecoPixelVertexing/PixelTriplets/plugins/CAHitNtupletGeneratorOnGPU.cc

Line 218 in bec73cc

PixelTrackHeterogeneous tracks(std::make_unique<pixelTrack::TrackSoA>());

?

makortel · 2021-07-28T21:04:01Z

I still don't understand why any cudaCheck(cudaDeviceSynchronize() added before return in

cmssw/RecoPixelVertexing/PixelTriplets/plugins/CAHitNtupletGeneratorOnGPU.cc

Line 214 in bec73cc

return tracks;

does not catch the error. But adding it into the destructor of CAHitNtupletGeneratorKernelsGPU

cmssw/RecoPixelVertexing/PixelTriplets/plugins/CAHitNtupletGeneratorKernels.h

Line 180 in bec73cc

~CAHitNtupletGeneratorKernels() = default;

does.

Just by poking around a bit I found out that without the zero hits protection it is specifically

cmssw/RecoPixelVertexing/PixelTriplets/plugins/CAHitNtupletGeneratorOnGPU.cc

Line 206 in bec73cc

kernels.classifyTuples(hits_d, soa, stream);

that causes the "illegal memory access" error.

Line 206 in bec73cc

kernels.classifyTuples(hits_d, soa, stream);

that causes the "illegal memory access" error.

To be even more specific, the following piece appears to be causing the error (when not including the zero hit check)

cmssw/RecoPixelVertexing/PixelTriplets/plugins/CAHitNtupletGeneratorKernels.cu

Lines 261 to 267 in e09e497

    
           if (params_.doSharedHitCut_) { 
        
             // remove duplicates (tracks that share a hit) 
        
             numberOfBlocks = (HitToTuple::capacity() + blockSize - 1) / blockSize; 
        
             kernel_sharedHitCleaner<<<numberOfBlocks, blockSize, 0, cudaStream>>>( 
        
                 hh.view(), tuples_d, tracks_d, quality_d, params_.minHitsForSharingCut_, device_hitToTuple_.get()); 
        
             cudaCheck(cudaGetLastError()); 
        
           }

This piece of code was changed in 12_0_X in #33371.

mmusich · 2021-07-29T08:41:48Z

thanks @makortel for the detailed analysis. see fix at #34684

perrotta · 2021-08-03T09:11:26Z

Can anybody confirm that #34684 fixed the issue also on hilton?
If so, this github issue can get closed (and concentrate on the Hcal ones reported in #34197)

mzarucki · 2021-08-03T09:30:00Z

Dear all,

I have just summarised our (TSG FOG) investigations into the different Pixel, HCAL and ECAL crashes that we were seeing related to the missing protections for when a subsystem is not included in the run: #34197

Concerning the Pixel PR #34684, as indicated (and reported in today's daily run meeting) we have tested it by pointing Hilton to a local CMSSW 11_3_3 install, with the PR included on top. We did not see any crashes when using the PixelOnly menu (e-log) when running over data from run 343762 which excludes ECAL, HCAL and Pixel.

Best regards,
Mateusz on behalf of TSG FOG

perrotta · 2021-08-10T06:45:51Z

Can this issue get closed now, then?

fwyzard · 2021-08-10T07:28:35Z

+heterogeneous

mzarucki · 2021-08-10T07:44:12Z

Dear all,

From the FOG side, I would like to report that we have tested the full GPU menu in CMSSW_11_3_4 in run 344449 with Pixel, ECAL and HCAL out of the run and we saw no issues (as reported in this e-log and today's Daily Run meeting just now). This confirms that the updated protections as working well.
