Input Parameters#
- queue
Device queue where calculations will be performed.
- n
Array of
group_countparametersng specifying the order of the matrices belonging to groupg(ng ≥ 0).- lda
Array of
group_countparametersldag specifying the leading dimension of the matrices belonging to groupg(ldag ≥max(1, ng)).- group_count
Specifies the number of groups of parameters. Must be at least 0.
- group_sizes
Array of
group_countintegers. Array element with indexgspecifies the number of problems to solve for each of the groups of parametersg. So the total number of problems to solve,batch_size, is a sum of all parameter group sizes.

Return Values#
The number of elements of type T the scratchpad memory to be passed
to the getri_batch (Group Version) function must be able to hold.
