Summary0004777: Histogram filter deadlocks on parallel server
DescriptionWhen you apply a probe filter when connected to a parallel server, it locks up PV. To replicate, simply do the following.

1. Connect to a server with at least 2 processes.
2. Create the Wavelet source.
3. Apply the Probe filter withe the default values.

Once you hit apply on the probe filter, the GUI becomes unresponsive. It never comes back.

 I just ran into the same problem with the histogram filter.

 Reduction filter was executing only on the 0th node since the output piece information was incorrect. Fixed that.

 Did this issue get fixed and then unfixed? I just got around to trying it now, and I'm still getting the same deadlock.

 Yup, this was "unfixed". It has been fixed, again. Number of partitions was getting set incorrectly on the client side update suppressor. This bug was exposed by recent changes.

 The probe filter now seems to work fine, but the histogram filter is freezing now. It deadlocks when I do the following:

1. Connect to a server with 2 or more processes.
2. Load disk_out_ref.
3. Run the histogram filter.

The deadlock does not occur when I use the wavelet source. Maybe it has to do with the exodus reader only outputting data on processes 0.

 Berk said he'll look into it.

 Histogram filter does not work well in parallel:
1. it deadlocks
2. it does not produce the right result

vtkPExtractHistogram should change to:
1. Compute the array range in parallel to determine bounds - ignore empty datasets
2. vtkExtractHistogram should use the given bounds and produce 0 if the array does not exist (no error!)
