The previous iniput size for both granularity and strong scaling tests where too big to meet the timing constrains needed for garlic. This patch sets a new, smaller, input size. Also, a minor cleanup is applied to the rest of the fwi experiments and figures.

# Strong scaling test for FWI variants based on tasks with and without I/O.
|
|
# This experiment solves a computationally expensive input which brings the
|
|
# storage devices to saturation when I/O is enabled. the same input us run
|
|
# without I/O for comparison purposes.. Also, the experiments are runt for a
|
|
# range of block sizes deemed as efficient according to the granularity
|
|
# experiment.
