// This file implements the Xsyrk routine. The precision is implemented using a template argument.
|
|
// The implementation is based on the regular Xgemm routine and kernel, but with two main changes:
|
|
// 1) The final unpad(transpose) kernel updates only the upper/lower triangular part.
|
|
// 2) The main Xgemm kernel masks workgroups not contributing to usefull data. This is only for
|
|
// performance reasons, as the actual masking is done later (see the first point).
