getrs_scratchpad_size
Computes size of scratchpad memory required for getrs (USM 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 getrs (buffer or USM version) function should be able to hold.
API
Syntax
namespace oneapi::mkl::lapack { template<typename T> std::int64_t getrs_scratchpad_size(sycl::queue &queue, mkl::transpose trans, std::int64_t n, std::int64_t nrhs, std::int64_t lda, std::int64_t ldb) }
Input Parameters
- queue
-
Device queue where calculations by the getrs (buffer or USM version) function will be performed.
- trans
-
Indicates the form of the equations:
If trans=mkl::transpose::nontrans, then A*X = B is solved for X.
If trans=mkl::transpose::trans, then AT*X = B is solved for X.
If trans=mkl::transpose::conjtrans, then AH*X = B is solved for X.
- n
-
The order of the matrix A and the number of rows in matrix B(0 ≤ n).
- nrhs
-
The number of right-hand sides (0 ≤ nrhs).
- lda
-
The leading dimension of a.
- ldb
-
The leading dimension of b.

Return Values
The number of elements of type T the scratchpad memory to be passed to the getrs (buffer or USM version) function must be able to hold.
