Tuning nw increases the performance on the tiny dataset:

[jxk588@gpu04:~/src/futhark]$ futhark bench --backend=opencl futhark-benchmarks/rodinia/nw/nw.fut
Compiling futhark-benchmarks/rodinia/nw/nw.fut...
Reporting average runtime of 10 runs for each dataset.

futhark-benchmarks/rodinia/nw/nw.fut (using nw.fut.tuning):
