Heat Transfer + BP File reader bug in some cases
Created by: pnorbert
Some values are incorrect in some cases. The example I found 4 writers 4 x 5 rows written, read by 3 processes (6,6 and 8 rows, resp.). Process 0's last row is incorrect. Everywhere else the data is correct.
$ mpirun -n 4 ./bin/heatTransfer_write_adios2 /home/adios/work/worktree/ADIOS2/release/examples/heatTransfer/heat_bpfile.xml heat_bpfile_4.bp 4 1 5 6 1 1
Step 1:
Total runtime = 0.0173781s
$ mpirun -n 3 ./bin/heatTransfer_read /home/adios/work/worktree/ADIOS2/release/examples/heatTransfer/heat_bpfile.xml heat_bpfile_4.bp 3 1
gndx = 20
gndy = 6
rank 0 reads 2D slice 6 x 6 from offset (0,0)
rank 2 reads 2D slice 8 x 6 from offset (12,0)
rank 1 reads 2D slice 6 x 6 from offset (6,0)

The file is correct, the bug is in the reader. ADIOS1 reader on the file produces the correct data. Also:
$ bpls -l heat_bpfile_4.bp -d T -n 6 -f "%6.2g" -c "-1,6,-1"
double T 2*{20, 6} = -3.6591 / 3.1591 / null / null
