Could someone remind me what the -m 0 and -m 1, and -H 0, 1, and 2 switches do? I'm finding it difficult to search for single letters.

From the readme:

"--single-memory [-m] list of flags (0 or 1) to make the devices
   allocate their scrypt scratchpad in a single,
   consecutive memory block. On Windows Vista, 7/8
   this may lead to a smaller memory size being used.
   When using the texture cache this option is implied."

"--hash-parallel [-H] scrypt also has a small SHA256 component to it:
   0 hashes this single threaded on the CPU.
   1 to enable multithreaded hashing on the CPU.
   2 offloads everything to the GPU (default)"

I have the most efficient results with m1 and h2 with my 780 ti in windows.
