SaveAnimation() silently hangs in parallel with pvbatch
We have a hang when running pvbatch, SaveAnimation(). Here is how to replicate.
-
5.3.0, Linux, local server.
-
Start trace.
-
Open can.exo. Apply.
-
Save Animation. Make the output movie larger than it currently is. Maybe 2000x1000. Save as .png. Note - what you have done in the trace is set Magnification = 2 in the SaveAnimation() line. This is what will cause the problem.
-
Stop trace. Save this trace somewhere.
-
Remove the animation .png files.
-
pvbatch the trace saved above. Not sure if it matters, I am running on 16 processes.
Nothing ever gets printed. If you change the Magnification = 1, all is well and you get your movie.
Also, notice that no warnings are shown, as mentioned in #17205 (closed), which is probably the same bug under the covers.
#17205 (closed) probable duplicate.
