  Parallelizing your serial 2D axisymmetric code from Lab6


Following the same  steps for parallelizing (and the experience of parallelizing your 1D code), 
now parallelize your 2D code along the z direction.

Your parallelized code should produce identical results with your serial code (on MMr=MMz=32 mesh)! 

With MMr = 32, try MMz = 64, 256, 512, ...   on  nWRs = 2 , 4 , 8 , ...

If on a cluster, you should be seeing speedup! 
In any case, calculate the Speedup and the Efficiency for each nWRs value.
Push it far enough till the gain starts leveling off.

To stay on one node of ACF (16 cores, so up to nWRs=15), can take Mz=600
and run on nWRs = 2, 5, 10, 15 to calculate Speedup.

Submit the following:

a.  max error (at tmax=1) from a run with MMr=32, MMz=256  on  nWRs= 4 workers.
--------------------------------------------------
b.  The speedup and efficiency values you obtained in your runs.
     A table of timings would be nice (on a fixed mesh, specify it):
	      nWRs     timing     Speedup    Efficiency 
     Specify what sort of system you made your runs on.
--------------------------------------------------
c.  lab9.zip  with ONLY the essential files of your code 
                       (z.* , Makefile , dat, how to run it)

    Hope you enjoyed the experience...
Now you can brag about it to your friends and in your CV !
