     10=== 2D ===
     11  AstroBEAR 2.0 has been tested in 2D with !MaxLevels of 0, 1, 2, & 4 and with base grids and refinement tolerances to give 8^2^, 16^2^, 32^2^, 64^2^, 128^2^, & 256^2^ cells per processor per level.  Both the threaded algorithm and the non-threaded algorithm have been tested.  The results are summarized in the following two figures.

    1319AstroBEAR 2.0 has been tested from 8 processors to 1024 processors on MSI's Itasca cluster.  Our test problem is a three-dimensional field cylinder advection problem with no source terms or elliptic calculations.  These are weak scaling fixed-grid tests where the workload is kept constant at 64^3^ cells per processor.
