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.

09271eda17 Add GNU OpenACC support for AMD GCN 
Autodetect the device type, rather than hard-code NVidia.

Add GNU command line options to the makefile, and adjust the "restrict"
extension usage. For now, we assume the toolchain is only configured for one
accelerator.

8776901733 [SYCL] Use the cl::sycl::id parameter in the parallel_for kernels 
The cl::sycl::item provides extra features for extracing global/local
ids which aren't required by the kernels.
This also means the kernels don't need to extract the id from the item.
