Expand description

Memory type specifier

Some memory types cannot be directly accessed on the host, e.g., CudaDevMem.

Variants

`SysMem`

System memory allocated with Rust’s global allocator

`AlignedSysMem`

Fields

align_bytes: usize

Aligned system memory allocated with Rust’s global allocator

Alignment is specified in bytes.

`NumaMem`

Fields

node: u16

page_type: PageType

NUMA memory allocated on the specified NUMA node and with the specified page type

`NumaPinnedMem`

Fields

node: u16

page_type: PageType

NUMA memory allocated on the specified NUMA node and pinned with CUDA

`DistributedNumaMem`

Fields

nodes: Box<[NodeRatio]>

page_type: PageType

NUMA memory distributed in proportion to a ratio over multiple NUMA nodes

`DistributedNumaMemWithLen`

Fields

nodes: Box<[NodeLen]>

page_type: PageType

NUMA memory distributed over multiple NUMA nodes using a length per node

`CudaPinnedMem`

CUDA pinned memory (using cudaHostAlloc())

`CudaUniMem`

CUDA unified memory

`CudaDevMem`

CUDA device memory
