BP threading problem
Created by: JasonRuonanWang
libc throws an exception when I run a casacore + Adios2StMan test.
The code writes one ADIOS variable with the dimension 10,000 x 1024 in float, from 12 MPI processes, each launching 4 threads in BP.
Each put writes a 1 x 1024 slices of the entire 10,000 x 1024 variable, and 12 MPI processes do round robin to fill all 10,000 slices
