#define CU_DEVICE_CPU ((CUdevice)-1)
Device that represents the CPU
#define CU_DEVICE_INVALID ((CUdevice)-2)
Device that represents an invalid device
#define CU_IPC_HANDLE_SIZE 64
CUDA IPC handle size
#define CU_LAUNCH_PARAM_BUFFER_POINTER ((void*)0x01)
Indicator that the next value in the extra parameter to cuLaunchKernel will be a pointer to a buffer containing all kernel parameters used for launching kernel f. This buffer needs to honor all alignment/padding requirements of the individual parameters. If CU_LAUNCH_PARAM_BUFFER_SIZE is not also specified in the extra array, then CU_LAUNCH_PARAM_BUFFER_POINTER will have no effect.
#define CU_LAUNCH_PARAM_BUFFER_SIZE ((void*)0x02)
Indicator that the next value in the extra parameter to cuLaunchKernel will be a pointer to a size_t which contains the size of the buffer specified with CU_LAUNCH_PARAM_BUFFER_POINTER. It is required that CU_LAUNCH_PARAM_BUFFER_POINTER also be specified in the extra array if the value associated with CU_LAUNCH_PARAM_BUFFER_SIZE is not zero.
#define CU_LAUNCH_PARAM_END ((void*)0x00)
End of array terminator for the extra parameter to cuLaunchKernel
#define CU_MEMHOSTALLOC_DEVICEMAP 0x02
If set, host memory is mapped into CUDA address space and cuMemHostGetDevicePointer() may be called on the host pointer. Flag for cuMemHostAlloc()
#define CU_MEMHOSTALLOC_PORTABLE 0x01
If set, host memory is portable between CUDA contexts. Flag for cuMemHostAlloc()
#define CU_MEMHOSTALLOC_WRITECOMBINED 0x04
If set, host memory is allocated as write-combined - fast to write, faster to DMA, slow to read except via SSE4 streaming load instruction (MOVNTDQA). Flag for cuMemHostAlloc()
#define CU_MEMHOSTREGISTER_DEVICEMAP 0x02
If set, host memory is mapped into CUDA address space and cuMemHostGetDevicePointer() may be called on the host pointer. Flag for cuMemHostRegister()
#define CU_MEMHOSTREGISTER_IOMEMORY 0x04
If set, the passed memory pointer is treated as pointing to some memory-mapped I/O space, e.g. belonging to a third-party PCIe device. On Windows the flag is a no-op. On Linux that memory is marked as non cache-coherent for the GPU and is expected to be physically contiguous. It may return CUDA_ERROR_NOT_PERMITTED if run as an unprivileged user, CUDA_ERROR_NOT_SUPPORTED on older Linux kernel versions. On all other platforms, it is not supported and CUDA_ERROR_NOT_SUPPORTED is returned. Flag for cuMemHostRegister()
#define CU_MEMHOSTREGISTER_PORTABLE 0x01
If set, host memory is portable between CUDA contexts. Flag for cuMemHostRegister()
#define CU_PARAM_TR_DEFAULT -1
For texture references loaded into the module, use default texunit from texture reference.
#define CU_STREAM_LEGACY ((CUstream)0x1)
Legacy stream handle
Stream handle that can be passed as a CUstream to use an implicit stream with legacy synchronization behavior.
See details of the .
#define CU_STREAM_PER_THREAD ((CUstream)0x2)
Per-thread stream handle
Stream handle that can be passed as a CUstream to use an implicit stream with per-thread synchronization behavior.
See details of the .
#define CU_TRSA_OVERRIDE_FORMAT 0x01
Override the texref format with a format inferred from the array. Flag for cuTexRefSetArray()
#define CU_TRSF_NORMALIZED_COORDINATES 0x02
Use normalized texture coordinates in the range [0,1) instead of [0,dim). Flag for cuTexRefSetFlags()
#define CU_TRSF_READ_AS_INTEGER 0x01
Read the texture as integers rather than promoting the values to floats in the range [0,1]. Flag for cuTexRefSetFlags()
#define CU_TRSF_SRGB 0x10
Perform sRGB->linear conversion during texture read. Flag for cuTexRefSetFlags()
#define CUDA_ARRAY3D_2DARRAY 0x01
Deprecated, use CUDA_ARRAY3D_LAYERED
#define CUDA_ARRAY3D_CUBEMAP 0x04
If set, the CUDA array is a collection of six 2D arrays, representing faces of a cube. The width of such a CUDA array must be equal to its height, and Depth must be six. If CUDA_ARRAY3D_LAYERED flag is also set, then the CUDA array is a collection of cubemaps and Depth must be a multiple of six.
#define CUDA_ARRAY3D_DEPTH_TEXTURE 0x10
This flag if set indicates that the CUDA array is a DEPTH_TEXTURE.
#define CUDA_ARRAY3D_LAYERED 0x01
If set, the CUDA array is a collection of layers, where each layer is either a 1D or a 2D array and the Depth member of CUDA_ARRAY3D_DESCRIPTOR specifies the number of layers, not the depth of a 3D array.
#define CUDA_ARRAY3D_SURFACE_LDST 0x02
This flag must be set in order to bind a surface reference to the CUDA array

enum CUresult
Error codes
Enumerator:
- CUDA_SUCCESS
- The API call returned with no errors. In the case of query calls, this can also mean that the operation being queried is complete (see cuEventQuery() and cuStreamQuery()).
- CUDA_ERROR_INVALID_VALUE
- This indicates that one or more of the parameters passed to the API call is not within an acceptable range of values.
- CUDA_ERROR_OUT_OF_MEMORY
- The API call failed because it was unable to allocate enough memory to perform the requested operation.
- CUDA_ERROR_NOT_INITIALIZED
- This indicates that the CUDA driver has not been initialized with cuInit() or that initialization has failed.
- CUDA_ERROR_DEINITIALIZED
- This indicates that the CUDA driver is in the process of shutting down.
- CUDA_ERROR_PROFILER_DISABLED
- This indicates profiler is not initialized for this run. This can happen when the application is running with external profiling tools like visual profiler.
- CUDA_ERROR_PROFILER_NOT_INITIALIZED
-
Deprecated
- This error return is deprecated as of CUDA 5.0. It is no longer an error to attempt to enable/disable the profiling via cuProfilerStart or cuProfilerStop without initialization.
- CUDA_ERROR_PROFILER_ALREADY_STARTED
-
Deprecated
- This error return is deprecated as of CUDA 5.0. It is no longer an error to call cuProfilerStart() when profiling is already enabled.
- CUDA_ERROR_PROFILER_ALREADY_STOPPED
-
Deprecated
- This error return is deprecated as of CUDA 5.0. It is no longer an error to call cuProfilerStop() when profiling is already disabled.
- CUDA_ERROR_NO_DEVICE
- This indicates that no CUDA-capable devices were detected by the installed CUDA driver.
- CUDA_ERROR_INVALID_DEVICE
- This indicates that the device ordinal supplied by the user does not correspond to a valid CUDA device.
- CUDA_ERROR_INVALID_IMAGE
- This indicates that the device kernel image is invalid. This can also indicate an invalid CUDA module.
- CUDA_ERROR_INVALID_CONTEXT
- This most frequently indicates that there is no context bound to the current thread. This can also be returned if the context passed to an API call is not a valid handle (such as a context that has had cuCtxDestroy() invoked on it). This can also be returned if a user mixes different API versions (i.e. 3010 context with 3020 API calls). See cuCtxGetApiVersion() for more details.
- CUDA_ERROR_CONTEXT_ALREADY_CURRENT
- This indicated that the context being supplied as a parameter to the API call was already the active context.
Deprecated
- This error return is deprecated as of CUDA 3.2. It is no longer an error to attempt to push the active context via cuCtxPushCurrent().
- CUDA_ERROR_MAP_FAILED
- This indicates that a map or register operation has failed.
- CUDA_ERROR_UNMAP_FAILED
- This indicates that an unmap or unregister operation has failed.
- CUDA_ERROR_ARRAY_IS_MAPPED
- This indicates that the specified array is currently mapped and thus cannot be destroyed.
- CUDA_ERROR_ALREADY_MAPPED
- This indicates that the resource is already mapped.
- CUDA_ERROR_NO_BINARY_FOR_GPU
- This indicates that there is no kernel image available that is suitable for the device. This can occur when a user specifies code generation options for a particular CUDA source file that do not include the corresponding device configuration.
- CUDA_ERROR_ALREADY_ACQUIRED
- This indicates that a resource has already been acquired.
- CUDA_ERROR_NOT_MAPPED
- This indicates that a resource is not mapped.
- CUDA_ERROR_NOT_MAPPED_AS_ARRAY
- This indicates that a mapped resource is not available for access as an array.
- CUDA_ERROR_NOT_MAPPED_AS_POINTER
- This indicates that a mapped resource is not available for access as a pointer.
- CUDA_ERROR_ECC_UNCORRECTABLE
- This indicates that an uncorrectable ECC error was detected during execution.
- CUDA_ERROR_UNSUPPORTED_LIMIT
- This indicates that the CUlimit passed to the API call is not supported by the active device.
- CUDA_ERROR_CONTEXT_ALREADY_IN_USE
- This indicates that the CUcontext passed to the API call can only be bound to a single CPU thread at a time but is already bound to a CPU thread.
- CUDA_ERROR_PEER_ACCESS_UNSUPPORTED
- This indicates that peer access is not supported across the given devices.
- CUDA_ERROR_INVALID_PTX
- This indicates that a PTX JIT compilation failed.
- CUDA_ERROR_INVALID_GRAPHICS_CONTEXT
- This indicates an error with OpenGL or DirectX context.
- CUDA_ERROR_NVLINK_UNCORRECTABLE
- This indicates that an uncorrectable NVLink error was detected during the execution.
- CUDA_ERROR_INVALID_SOURCE
- This indicates that the device kernel source is invalid.
- CUDA_ERROR_FILE_NOT_FOUND
- This indicates that the file specified was not found.
- CUDA_ERROR_SHARED_OBJECT_SYMBOL_NOT_FOUND
- This indicates that a link to a shared object failed to resolve.
- CUDA_ERROR_SHARED_OBJECT_INIT_FAILED
- This indicates that initialization of a shared object failed.
- CUDA_ERROR_OPERATING_SYSTEM
- This indicates that an OS call failed.
- CUDA_ERROR_INVALID_HANDLE
- This indicates that a resource handle passed to the API call was not valid. Resource handles are opaque types like CUstream and CUevent.
- CUDA_ERROR_NOT_FOUND
- This indicates that a named symbol was not found. Examples of symbols are global/constant variable names, texture names, and surface names.
- CUDA_ERROR_NOT_READY
- This indicates that asynchronous operations issued previously have not completed yet. This result is not actually an error, but must be indicated differently than CUDA_SUCCESS (which indicates completion). Calls that may return this value include cuEventQuery() and cuStreamQuery().
- CUDA_ERROR_ILLEGAL_ADDRESS
- While executing a kernel, the device encountered a load or store instruction on an invalid memory address. The context cannot be used, so it must be destroyed (and a new one should be created). All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.
- CUDA_ERROR_LAUNCH_OUT_OF_RESOURCES
- This indicates that a launch did not occur because it did not have appropriate resources. This error usually indicates that the user has attempted to pass too many arguments to the device kernel, or the kernel launch specifies too many threads for the kernel's register count. Passing arguments of the wrong size (i.e. a 64-bit pointer when a 32-bit int is expected) is equivalent to passing too many arguments and can also result in this error.
- CUDA_ERROR_LAUNCH_TIMEOUT
- This indicates that the device kernel took too long to execute. This can only occur if timeouts are enabled - see the device attribute CU_DEVICE_ATTRIBUTE_KERNEL_EXEC_TIMEOUT for more information. The context cannot be used (and must be destroyed similar to CUDA_ERROR_LAUNCH_FAILED). All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.
- CUDA_ERROR_LAUNCH_INCOMPATIBLE_TEXTURING
- This error indicates a kernel launch that uses an incompatible texturing mode.
- CUDA_ERROR_PEER_ACCESS_ALREADY_ENABLED
- This error indicates that a call to cuCtxEnablePeerAccess() is trying to re-enable peer access to a context which has already had peer access to it enabled.
- CUDA_ERROR_PEER_ACCESS_NOT_ENABLED
- This error indicates that cuCtxDisablePeerAccess() is trying to disable peer access which has not been enabled yet via cuCtxEnablePeerAccess().
- CUDA_ERROR_PRIMARY_CONTEXT_ACTIVE
- This error indicates that the primary context for the specified device has already been initialized.
- CUDA_ERROR_CONTEXT_IS_DESTROYED
- This error indicates that the context current to the calling thread has been destroyed using cuCtxDestroy, or is a primary context which has not yet been initialized.
- CUDA_ERROR_ASSERT
- A device-side assert triggered during kernel execution. The context cannot be used anymore, and must be destroyed. All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.
- CUDA_ERROR_TOO_MANY_PEERS
- This error indicates that the hardware resources required to enable peer access have been exhausted for one or more of the devices passed to cuCtxEnablePeerAccess().
- CUDA_ERROR_HOST_MEMORY_ALREADY_REGISTERED
- This error indicates that the memory range passed to cuMemHostRegister() has already been registered.
- CUDA_ERROR_HOST_MEMORY_NOT_REGISTERED
- This error indicates that the pointer passed to cuMemHostUnregister() does not correspond to any currently registered memory region.
- CUDA_ERROR_HARDWARE_STACK_ERROR
- While executing a kernel, the device encountered a stack error. This can be due to stack corruption or exceeding the stack size limit. The context cannot be used, so it must be destroyed (and a new one should be created). All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.
- CUDA_ERROR_ILLEGAL_INSTRUCTION
- While executing a kernel, the device encountered an illegal instruction. The context cannot be used, so it must be destroyed (and a new one should be created). All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.
- CUDA_ERROR_MISALIGNED_ADDRESS
- While executing a kernel, the device encountered a load or store instruction on a memory address which is not aligned. The context cannot be used, so it must be destroyed (and a new one should be created). All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.
- CUDA_ERROR_INVALID_ADDRESS_SPACE
- While executing a kernel, the device encountered an instruction which can only operate on memory locations in certain address spaces (global, shared, or local), but was supplied a memory address not belonging to an allowed address space. The context cannot be used, so it must be destroyed (and a new one should be created). All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.
- CUDA_ERROR_INVALID_PC
- While executing a kernel, the device program counter wrapped its address space. The context cannot be used, so it must be destroyed (and a new one should be created). All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.
- CUDA_ERROR_LAUNCH_FAILED
- An exception occurred on the device while executing a kernel. Common causes include dereferencing an invalid device pointer and accessing out of bounds shared memory. The context cannot be used, so it must be destroyed (and a new one should be created). All existing device memory allocations from this context are invalid and must be reconstructed if the program is to continue using CUDA.
- CUDA_ERROR_NOT_PERMITTED
- This error indicates that the attempted operation is not permitted.
- CUDA_ERROR_NOT_SUPPORTED
- This error indicates that the attempted operation is not supported on the current system or device.
- CUDA_ERROR_UNKNOWN
- This indicates that an unknown internal error has occurred.
enum CUsharedconfig
Shared memory configurations
Enumerator:
- CU_SHARED_MEM_CONFIG_DEFAULT_BANK_SIZE
- set default shared memory bank size
- CU_SHARED_MEM_CONFIG_FOUR_BYTE_BANK_SIZE
- set shared memory bank width to four bytes
- CU_SHARED_MEM_CONFIG_EIGHT_BYTE_BANK_SIZE
- set shared memory bank width to eight bytes
enum CUstream_flags
Stream creation flags
Enumerator:
- CU_STREAM_DEFAULT
- Default stream flag
- CU_STREAM_NON_BLOCKING
- Stream does not synchronize with stream 0 (the NULL stream)
enum CUstreamBatchMemOpType
Operations for cuStreamBatchMemOp
Enumerator:
- CU_STREAM_MEM_OP_WAIT_VALUE_32
- Represents a cuStreamWaitValue32 operation
- CU_STREAM_MEM_OP_WRITE_VALUE_32
- Represents a cuStreamWriteValue32 operation
- CU_STREAM_MEM_OP_FLUSH_REMOTE_WRITES
- This has the same effect as CU_STREAM_WAIT_VALUE_FLUSH, but as a standalone operation.
enum CUstreamWaitValue_flags
Flags for cuStreamWaitValue32
Enumerator:
- CU_STREAM_WAIT_VALUE_GEQ
- Wait until (int32_t)(*addr - value) >= 0. Note this is a cyclic comparison which ignores wraparound. (Default behavior.)
- CU_STREAM_WAIT_VALUE_EQ
- Wait until *addr == value.
- CU_STREAM_WAIT_VALUE_AND
- Wait until (*addr & value) != 0.
- CU_STREAM_WAIT_VALUE_FLUSH
- Follow the wait operation with a flush of outstanding remote writes. This means that, if a remote write operation is guaranteed to have reached the device before the wait can be satisfied, that write is guaranteed to be visible to downstream device work. The device is permitted to reorder remote writes internally. For example, this flag would be required if two remote writes arrive in a defined order, the wait is satisfied by the second write, and downstream work needs to observe the first write.
enum CUstreamWriteValue_flags
Flags for cuStreamWriteValue32
Enumerator:
- CU_STREAM_WRITE_VALUE_DEFAULT
- Default behavior
- CU_STREAM_WRITE_VALUE_NO_MEMORY_BARRIER
- Permits the write to be reordered with writes which were issued before it, as a performance optimization. Normally, cuStreamWriteValue32 will provide a memory fence before the write, which has similar semantics to __threadfence_system() but is scoped to the stream rather than a CUDA thread.
