Hi,

I am  reading "strsm.cu" code and inside of it I am seeing "magmablas_strtri_diag" to understand it I have to find the cuda kernel for "triple_sgemmXX_partX_lower_kernel" (and some other similar kernels) but I am not finding theme.
Are they a MAGMA kernel or cuBLAS?

Best regards,
Aran

Almost all the source code of MAGMA is done in double complex precision ‘z’. During compilation, all the other precisions are auto-generated. Try replacing the ’s’ precision in your search string to ‘z’.

Thanks. But it seems that again I am not able to find corresponding kernel.

For example this function in "ztrtri.cuh":

__global__ void
triple_zgemm16_part1_lower_kernel(
    int n, const magmaDoubleComplex *Ain, int lda, magmaDoubleComplex *d_invA, int jb, int npages);
