Detailed Description

Element-wise equality comparison algorithms for buffers.

Author

This header provides parallel algorithms to compare two buffers element-wise for equality. The functions perform element-wise comparisons across entire buffers or specified ranges, returning true only if all corresponding elements are equal.

The algorithms come in several variants:

• equals for sycl::buffer: Direct buffer-based processing (deprecated)
• equals for sham::DeviceBuffer: USM-based processing
• equals_ptr and equals_ptr_s: Comparison of unique_ptr-wrapped buffers
