I recommend posting this on the FSL list, as it suggests a bug with eddy and 
probably that is more likely to be answered on the FSL list.

Peace,

Matt.

Subject: [HCP-Users] core dump running dMRI pipeline

I am getting a core dump while trying to run the HCP dMRI pipeline, using the 
HCP 3.22 release, FSL 5.0.10, a newer card (Tesla P100 compute 12Gb cap 6.0), 
with a RH7 OS. The error I am getting is:

thrust::system_error thrown in CudaVolume::common_assignment_from_newimage_vol 
after resize() with message: function_attributes(): after 
cudaFuncGetAttributes: invalid device function
terminate called after throwing an instance of 'thrust::system::system_error'
  what():  function_attributes(): after cudaFuncGetAttributes: invalid device 
function
/opt/local/hcp-pipelines-3.22.0/Pipelines-3.22.0/DiffusionPreprocessing/scripts/run_eddy.sh:
 line 380: 25767 Aborted                 (core dumped) ${eddy_command}

The last few lines in the .o file shows the call to eddy_cuda and then:
Entering EddyGpuUtils::LoadPredictionMaker

...................Allocated GPU # 0...................
Mon Oct 30 18:56:24 CDT 2017 - run_eddy.sh - Completed with return value: 134

I have the cuda 7.5 libraries installed and ldd shows eddy_cuda resolving all 
the libraries. Any suggestions?

Thanks,

Bryon
