Computes size of scratchpad memory required for getrs_batch (Strided Version) function. This routine belongs to the mkl::lapack namespace.
std::int64_t getrs_batch_scratchpad_size(cl::sycl::queue &queue, mkl::transpose trans, std::int64_t n, std::int64_t nrhs, std::int64_t lda, std::int64_t stride_a, std::int64_t stride_ipiv, std::int64_t ldb, std::int64_t stride_b, std::int64_t batch_size);
Computes the number of elements of type T the scratchpad memory to be passed to the getrs_batch (Strided Version) function should be able to hold.
Device queue where calculations will be performed.
Indicates the form of the equations:
If trans = mkl::transpose::nontrans, then Ai*Xi = Bi is solved for Xi.
If trans = mkl::transpose::trans, then AiT*Xi = Bi is solved for Xi.
If trans = mkl::transpose::conjtrans, then AiH*Xi = Bi is solved for Xi.
The order of the matrices Ai and the number of rows in matrices Bi (0 ≤ n).
The number of right hand sides (0≤nrhs).
The leading dimension of Ai.
The stride between the beginnings of matrices Bi inside the batch array b.
The stride between the beginnings of arrays ipivi inside the array ipiv.
The leading dimensions of Bi.
Specifies the number of problems in a batch.
Exceptions
