9. Deprecated List

Global CU_CTX_BLOCKING_SYNC

This flag was deprecated as of CUDA 4.0 and was replaced with CU_CTX_SCHED_BLOCKING_SYNC.

Global CU_CTX_MAP_HOST

This flag was deprecated as of CUDA 11.0 and it no longer has any effect. All contexts as of CUDA 3.2 behave as though the flag is enabled.

Global CU_DEVICE_P2P_ATTRIBUTE_ACCESS_ACCESS_SUPPORTED

use CU_DEVICE_P2P_ATTRIBUTE_CUDA_ARRAY_ACCESS_SUPPORTED instead

Global CU_JIT_NEW_SM3X_OPT

This jit option is deprecated and should not be used.

Global CU_JIT_LTO

Enable link-time optimization (-dlto) for device code (Disabled by default).

This option is not supported on 32-bit platforms.

Option type: int

Applies to: compiler and linker

Global CU_JIT_FTZ

Control single-precision denormals (-ftz) support (0: false, default). 1 : flushes denormal values to zero 0 : preserves denormal values Option type: int

Applies to: link-time optimization specified with CU_JIT_LTO

Global CU_JIT_PREC_DIV

Control single-precision floating-point division and reciprocals (-prec-div) support (1: true, default). 1 : Enables the IEEE round-to-nearest mode 0 : Enables the fast approximation mode Option type: int

Applies to: link-time optimization specified with CU_JIT_LTO

Global CU_JIT_PREC_SQRT

Control single-precision floating-point square root (-prec-sqrt) support (1: true, default). 1 : Enables the IEEE round-to-nearest mode 0 : Enables the fast approximation mode Option type: int

Applies to: link-time optimization specified with CU_JIT_LTO

Global CU_JIT_FMA

Enable/Disable the contraction of floating-point multiplies and adds/subtracts into floating-point multiply-add (-fma) operations (1: Enable, default; 0: Disable). Option type: int

Applies to: link-time optimization specified with CU_JIT_LTO

Global CU_JIT_REFERENCED_KERNEL_NAMES

Array of kernel names that should be preserved at link time while others can be removed.

Must contain CU_JIT_REFERENCED_KERNEL_COUNT entries.

Note that kernel names can be mangled by the compiler in which case the mangled name needs to be specified.

Wildcard "*" can be used to represent zero or more characters instead of specifying the full or mangled name.

It is important to note that the wildcard "*" is also added implicitly. For example, specifying "foo" will match "foobaz", "barfoo", "barfoobaz" and thus preserve all kernels with those names. This can be avoided by providing a more specific name like "barfoobaz".

Option type: const char **

Applies to: dynamic linker only

Global CU_JIT_REFERENCED_KERNEL_COUNT

Number of entries in CU_JIT_REFERENCED_KERNEL_NAMES array.

Option type: unsigned int

Applies to: dynamic linker only

Global CU_JIT_REFERENCED_VARIABLE_NAMES

Array of variable names (__device__ and/or __constant__) that should be preserved at link time while others can be removed.

Must contain CU_JIT_REFERENCED_VARIABLE_COUNT entries.

Note that variable names can be mangled by the compiler in which case the mangled name needs to be specified.

Wildcard "*" can be used to represent zero or more characters instead of specifying the full or mangled name.

It is important to note that the wildcard "*" is also added implicitly. For example, specifying "foo" will match "foobaz", "barfoo", "barfoobaz" and thus preserve all variables with those names. This can be avoided by providing a more specific name like "barfoobaz".

Option type: const char **

Applies to: link-time optimization specified with CU_JIT_LTO

Global CU_JIT_REFERENCED_VARIABLE_COUNT

Number of entries in CU_JIT_REFERENCED_VARIABLE_NAMES array.

Option type: unsigned int

Applies to: link-time optimization specified with CU_JIT_LTO

Global CU_JIT_OPTIMIZE_UNUSED_DEVICE_VARIABLES

This option serves as a hint to enable the JIT compiler/linker to remove constant (__constant__) and device (__device__) variables unreferenced in device code (Disabled by default).

Note that host references to constant and device variables using APIs like cuModuleGetGlobal() with this option specified may result in undefined behavior unless the variables are explicitly specified using CU_JIT_REFERENCED_VARIABLE_NAMES.

Option type: int

Applies to: link-time optimization specified with CU_JIT_LTO

Global CU_JIT_INPUT_NVVM

High-level intermediate code for link-time optimization

Applicable options: NVVM compiler options, PTX compiler options
