Dear all, I have downloaded from the 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@01D217E4.08171B00] 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@01D217E4.08171B00] 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@01D217E4.08171B00] Was this behavior to be expected? Please let me know if there is any interest in providing with my benchmark. Frank Albina
