queue

Device queue where calculations will be performed.

uplo

Indicates whether the upper or lower triangular part of

A

i

is stored and how

A

i

is factored:

If uplo = mkl::uplo::upper, the array

a

stores the upper triangular parts of the matrices

A

i

.

If uplo = mkl::uplo::lower, the array

a

stores the lower triangular parts of the matrices

A

i

.

n

Specifies the order of the matrices

A

i

, (

0 ≤ n

).

lda

The leading dimension of

A

i

.

stride_a

The stride between the beginnings of matrices

A

i

inside the batch.

batch_size

Specifies the number of problems in a batch.
