829aa15da0 Allocate driver solution check vectors *after* the main computation 
Each Stream implementation owns its own data, so the driver code
shouldn't allocate a large array just before. On processors with
strong NUMA effects and smaller memory capacities per NUMA domain,
these checking vectors can result in the main arrays being
allocated in the wrong NUMA domain.

The fix is to simply move the driver allocation until after the
computation has finished and we want to check the answers.

This commit only changes the driver; each model will be updated
in subsequent commits.

Fixes #80.

0855805ce2 Add NVIDIA HPC SDK C++ parallel STL implementation 
This commits adds an implementation using the C++ parallel STL.
The Makefile uses the NVIDIA HPC SDK `nvc++` compiler with the `-stdpar` flag.
Tested using the NVIDIA HPC SDK 20.9.

5a1396671e Add a --mibibytes flag to output bandwidth and array sizes in base 2 
This sets MiB = 2^20, GiB = 2^30 rather than the default of
MB = 10^6 and GB = 10^9.
