Hi Ken! Sure will do. I’ll come back to you asap with a self-contained test loop using your shuttle data.

Could you update your script to use the shuttle dataset? I included a copy of that data on this email. That would make it easier to debug. Thanks Ken On Mon, Sep 26, 2016 at 4:55 AM, Albina, Frank <frank.alb...@sauber-motorsport.com<mailto:frank.alb...@sauber-motorsport.com>> wrote: Dear all, I have downloaded from the paraview.org<http://paraview.org> the latest binaries for Linux of ParaView v5.1.2. My main purpose is to make use of ParaView with software rendering in a clustered environment without GPU and, as such, I have been going through my small benchmark on a generic F1 car. This what I have found so far when generating a SurfaceLIC representation on the whole car surface in batch mode. Using pvbatch –mesa-llvm works fine. This is one of the produced images for reference: [cid:image001.jpg@01D219AE.D5764EB0] Using 4 cores to perform the same task (with the same script) with mpiexec –np 4 pvbatch --mesa-llvm shows a good speed-up but the background is black instead of white (although view.Backgound = [1,1,1] is set explicitely), as shown hereafter: [cid:image002.jpg@01D219AE.D5764EB0] On the same server (Intel Xeon ES-2650 v3), the CPU is AVX2 capable, so I tried also the same script with pvbatch --mesa-swr-avx2. The image background is corrupted with leftover frames apparently, as shown hereafter: [cid:image003.jpg@01D219AE.D5764EB0] Was this behavior to be expected? Please let me know if there is any interest in providing with my benchmark.
