A fork of Eigen 3.2 to use MAGMA (GPU & CPU) as backend in the same way it does with Intel MKL.

eigen-magma's Issues

add support for ?getrf

add support for PartialPivLU corresponding to ?getrf

Is support window system?

Dose the project support window system?

Broken with magma 1.5 due to change in magma_vec_t

Hey,

Compilation breaks with magma 1.5 due to change in the typedef of magma_vec_t

1.4.1:

typedef char magma_vec_t;

1.5

typedef enum {
    MagmaNoVec         = 301,  /* geev, syev, gesvd */
    MagmaVec           = 302,  /* geev, syev */
    MagmaIVec          = 303,  /* stedc */
    MagmaAllVec        = 304,  /* gesvd, trevc */
    MagmaSomeVec       = 305,  /* gesvd, trevc */
    MagmaOverwriteVec  = 306,  /* gesvd */
    MagmaBacktransVec  = 307   /* trevc */
} magma_vec_t;

This breaks compilation of Eigen/src/SVD/JacobiSVD_MAGMA.h because magma_vec_t is an enum now and these options need to be parsed differently:

  jobu  = (m_computeFullU) ? 'A' : (m_computeThinU) ? 'S' : 'N'; \
  jobvt = (m_computeFullV) ? 'A' : (m_computeThinV) ? 'S' : 'N'; \

I will attach a patch shortly.

Won't recommend using this in 2021

Hey, just a heads up for anyone trying, go search for another library. I tried this on linux, and I failed misrably. You need some intel libraries which are hard to obtain. The intel parallel studio is discontinued, and the AUR package for it doesn't even work by now. And no, i am not going to download 23 GB just for some new shiny intel compilers and libraries.

I am going to try this: eigen-cuda
This works perfectly, but isn't really Eigen. But you can initialize matrices by an Eigen matrix.

Is this finished?

Nevermind.
