I just installed magma and I noticed that some routines have _mgpu version while some not. For example for LU inverse, there are 4 functions:
magma_cgetri_gpu (magma_int_t n, magmaFloatComplex_ptr dA, magma_int_t ldda, magma_int_t *ipiv, magmaFloatComplex_ptr dwork, magma_int_t lwork, magma_int_t *info)
magma_dgetri_gpu (magma_int_t n, magmaDouble_ptr dA, magma_int_t ldda, magma_int_t *ipiv, magmaDouble_ptr dwork, magma_int_t lwork, magma_int_t *info)
magma_sgetri_gpu (magma_int_t n, magmaFloat_ptr dA, magma_int_t ldda, magma_int_t *ipiv, magmaFloat_ptr dwork, magma_int_t lwork, magma_int_t *info)
magma_zgetri_gpu (magma_int_t n, magmaDoubleComplex_ptr dA, magma_int_t ldda, magma_int_t *ipiv, magmaDoubleComplex_ptr dwork, magma_int_t lwork, magma_int_t *info)
There is no _mgpu function for LU inverse, and there is also no relevant input parameter in these gpu functions that indicating the number of GPUs to use. Dose this mean there functions without '_mpu' suffix cannot use multiple GPUs? If the answer is no, how to do it?
Here is the link to the documentation: http://icl.cs.utk.edu/projectsfiles/magma/doxygen/group__magma__getri.html
Thank you very much!
