type : cudaMemoryType
The type of memory - cudaMemoryTypeUnregistered,
cudaMemoryTypeHost, cudaMemoryTypeDevice or cudaMemoryTypeManaged.
device : int
The device against which the memory was allocated or registered. If
the memory type is cudaMemoryTypeDevice then this identifies the
device on which the memory referred physically resides. If the
memory type is cudaMemoryTypeHost or::cudaMemoryTypeManaged then
this identifies the device which was current when the memory was
allocated or registered (and if that device is deinitialized then
this allocation will vanish with that device's state).
devicePointer : Any
The address which may be dereferenced on the current device to
access the memory or NULL if no such address exists.
hostPointer : Any
The address which may be dereferenced on the host to access the
memory or NULL if no such address exists. CUDA doesn't check if
unregistered memory is allocated so this field may contain invalid
pointer if an invalid pointer has been passed to CUDA.

CUDA function attributes
Attributes
----------
sharedSizeBytes : size_t
The size in bytes of statically-allocated shared memory per block
required by this function. This does not include dynamically-
allocated shared memory requested by the user at runtime.
constSizeBytes : size_t
The size in bytes of user-allocated constant memory required by
this function.
localSizeBytes : size_t
The size in bytes of local memory used by each thread of this
function.
maxThreadsPerBlock : int
The maximum number of threads per block, beyond which a launch of
the function would fail. This number depends on both the function
and the device on which the function is currently loaded.
numRegs : int
The number of registers used by each thread of this function.
ptxVersion : int
The PTX virtual architecture version for which the function was
compiled. This value is the major PTX version * 10 + the minor PTX
version, so a PTX version 1.3 function would return the value 13.
binaryVersion : int
The binary architecture version for which the function was
compiled. This value is the major binary version * 10 + the minor
binary version, so a binary version 1.3 function would return the
value 13.
cacheModeCA : int
The attribute to indicate whether the function has been compiled
with user specified option "-Xptxas --dlcm=ca" set.
maxDynamicSharedSizeBytes : int
The maximum size in bytes of dynamic shared memory per block for
this function. Any launch must have a dynamic shared memory size
smaller than this value.
preferredShmemCarveout : int
On devices where the L1 cache and shared memory use the same
hardware resources, this sets the shared memory carveout
preference, in percent of the maximum shared memory. Refer to
cudaDevAttrMaxSharedMemoryPerMultiprocessor. This is only a hint,
and the driver can choose a different ratio if required to execute
the function. See cudaFuncSetAttribute
clusterDimMustBeSet : int
If this attribute is set, the kernel must launch with a valid
cluster dimension specified.
requiredClusterWidth : int
The required cluster width/height/depth in blocks. The values must
either all be 0 or all be positive. The validity of the cluster
dimensions is otherwise checked at launch time. If the value is
set during compile time, it cannot be set at runtime. Setting it at
runtime should return cudaErrorNotPermitted. See
cudaFuncSetAttribute
requiredClusterHeight : int
requiredClusterDepth : int
clusterSchedulingPolicyPreference : int
The block scheduling policy of a function. See cudaFuncSetAttribute
nonPortableClusterSizeAllowed : int
Whether the function can be launched with non-portable cluster
size. 1 is allowed, 0 is disallowed. A non-portable cluster size
may only function on the specific SKUs the program is tested on.
The launch might fail if the program is run on a different hardware
platform. CUDA API provides cudaOccupancyMaxActiveClusters to
assist with checking whether the desired size can be launched on
the current device. Portable Cluster Size A portable cluster size
is guaranteed to be functional on all compute capabilities higher
than the target compute capability. The portable cluster size for
sm_90 is 8 blocks per cluster. This value may increase for future
compute capabilities. The specific hardware unit may support
higher cluster sizes that’s not guaranteed to be portable. See
cudaFuncSetAttribute
deviceNodeUpdateStatus : int
Whether the function can be updated on device. 1 means device node
update is supported, 0 is unsupported or driver is too old to check
the value.
reserved1 : int
reserved : list[int]
Reserved for future use.
