zgemm for matrices that don't fit

Hi,

I need to multiply matrices of size 12000x12000. 3 of these matrices don't fit in a GPU so I can't use cuBLAS. I'm not able to use magmablas_zgemm either as it works on matrices in GPU memory.

Is there a method in MAGMA or some other library which takes matrices in RAM larger than GPU memory and does zgemm using the GPU?

Thanks,
Harshad

You can try the new NVIDIA cuBLAS-XT library. See:
