3.7 Device Memory Routines ¶

Routines related to memory allocation and managing corresponding pointers on devices. They have C linkage and do not throw exceptions.

• omp_target_alloc – Allocate device memory
• omp_target_free – Free device memory
• omp_target_is_present – Check whether storage is mapped
• omp_target_is_accessible – Check whether memory is device accessible
• omp_target_memcpy – Copy data between devices
• omp_target_memcpy_async – Copy data between devices asynchronously
• omp_target_memcpy_rect – Copy a subvolume of data between devices
• omp_target_memcpy_rect_async – Copy a subvolume of data between devices asynchronously
• omp_target_associate_ptr – Associate a device pointer with a host pointer
• omp_target_disassociate_ptr – Remove device–host pointer association
• omp_get_mapped_ptr – Return device pointer to a host pointer
