kmsmith137 / n2k

N^2 kernel for radio astronomy (experimental)

Build instructions:

git clone https://github.com/kmsmith137/gputils
cd gputils
make -j
cd ..

git clone https://github.com/kmsmith137/n2k
cd n2k
make -j
./test-correlator

Some loose ends that I might fix later. Let me know if you'd like me to prioritize any of these. See n2k.hpp for more info:

• Currently, we only support 4+4 bit electric field samples, in the range [-7,7]. If the value (-8) arises, then the output of the computation will be incorrect!

• The kernel will segfault if run on a GPU which is not the cuda default device.
