This header provides parallel algorithms to check if all elements in a buffer are non-zero (logically true). The functions perform a boolean reduction operation across the entire buffer, returning true only if every element satisfies the non-zero condition.

The algorithms come in two variants:

• is_all_true for sycl::buffer: Direct buffer-based processing
• is_all_true for sham::DeviceBuffer: USM-based processing
