Adding CUDA multi-GPU support to OmicABEL for computing GWAS quickly.

You need the following dependencies:

OmicABEL heavily relies on GotoBLAS2. Use the following to install it:

$ cd ~
$ wget http://www.tacc.utexas.edu/documents/13601/b58aeb8c-9d8d-4ec2-b5f1-5a5843b4d47b -O GotoBLAS2-1.13.tar.gz
$ tar -xzvf GotoBLAS2-1.13.tar.gz
$ cd GotoBLAS2
$ make TARGET=NEHALEM

You can drop the TARGET=NEHALEM option, but you will then get compile errors on modern Intel-processors because it doesn't recognize them. make clean in case that happens.

Same here; install it using the following commands:

$ cd ~
$ wget http://www.netlib.org/lapack/lapack-3.4.2.tgz
$ tar -xzvf lapack-3.4.2.tgz
$ mv lapack-3.4.2 lapack
$ cd lapack
$ cp make.inc.example make.inc

Edit that file so that at the bottom, it shows the following:

BLASLIB      = ~/GotoBLAS2/libgoto2.a

Then, compile it by running make. At some point, the tests will likely fail due to a linker error. We could fix this by linking the tests with pthreads, but we do not really care about them anyways; as long as there is a liblapack.a file, you're fine. Still need to create a differently named link to it for OmicABEL: ln -s liblapack.a lapack_LINUX.a.

In case you installed GotoBLAS2 and LAPACK in other directories, you'll need to edit the make.inc file accordingly.

Besides that, cuOmicABEL should be compiled simply by running make.
