To generate a dataset, first run XSBench itself to generate a data file:

$ ./XSBench -s small -m event -b write

This produces XS_data.dat. Pass this though the data2fut program to generate a Futhark-readable binary data file:

$ ./data2fut < XS_data.dat > futhark.in

You may need to modify data2fut.c. I only tested that it could handle the small and large datasets. The bigger ones require an impractical amount of memory.
