I’m attaching a simple code that illustrates the problem. I open a
mesh (l_problem.xda) and perform a uniform refinement (if I don’t,
there are no problems), then I create an ExplicitSystem and assign
random values to its solution. I print the solution for verification
purposes. I save both the equation system and the refined mesh. Then
I rerun the code reading the saved data and the saved mesh and print
the solution to compare it with the previous run. Running the code
in parallel, if my mesh is SerialMesh, both solutions coincide,
however if my mesh is plain Mesh, I get this assertion error:
Assertion `cnt < io_buffer.size()' failed.
cnt = 12755
io_buffer.size() = 12755
The program would be run with the following flags
mpirun –n 2 ./program –uniref 1 –read_sol 0 > output1.txt
Rerun:
mpirun –n 2 ./program –uniref 1 –read_sol 1 > output2.txt
Thanks!
I can reproduce this with the latest libMesh. I'll see if I can
bisect it.
