allocate()

void* umpire::alloc::SyclMallocAllocator::allocate ( std::size_t  size, const sycl::queue &  queue_t  )

inline

Allocate bytes of memory using SYCL malloc.

Parameters

size	Number of bytes to allocate.
queue_t	SYCL queue for providing information on device and context

Returns

Pointer to start of the allocation on device.

Exceptions
