std::uint32_t u32
32 bit unsigned integer
A buffer allocated in USM (Unified Shared Memory)
namespace for primitive algorithm (e.g. sort, scan, reductions, ...)
sham::DeviceBuffer< u32 > gen_buffer_index(sham::DeviceScheduler_ptr sched, u32 len)
Generates a buffer where buf[i] = i.
void fill_buffer_index(sham::DeviceBuffer< u32 > &buf, u32 len)
Fills a buffer with sequential indices, such that buf[i] = i.
