getrsnp_batch_scratchpad_size (Strided Version)
Computes size of scratchpad memory required for getrsnp_batch (Strided Version) function. This routine belongs to the oneapi::mkl::lapack namespace.
Description
Computes the number of elements of type T the scratchpad memory to be passed to the getrsnp_batch (Strided Version) function must be able to hold.
API
Syntax
namespace oneapi::mkl::lapack {
std::int64_t getrsnp_batch_scratchpad_size(sycl::queue &queue,
mkl::transpose trans,
std::int64_t n,
std::int64_t nrhs,

}Input Parameters
- queue
-
Device queue where calculations will be performed.
- trans
-
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.
- n
-
The order of the matrices Ai and the number of rows in matrices Bi (n ≥ 0).
- nrhs
-
The number of right hand sides (nrhs ≥ 0).
- lda
-
The leading dimension of Ai (lda ≥ max(1, n)).
- stride_a
-
The stride between the beginnings of matrices Ai inside the batch array a (stride_a ≥ max(1, lda * n)).
- ldb
-
The leading dimensions of Bi (ldb ≥ max(1, n)).
- stride_b
-
The stride between the beginnings of matrices Bi inside the batch array b (stride_b ≥ max(1, ldb * nrhs)).
- batch_size
-
The number of problems in a batch (batch_size ≥ 0).
