Module Management
A reference to a Module object, containing collections of device functions
Just-in-time compilation options
Constructors
| MaxRegisters !Int | maximum number of registers per thread |
| ThreadsPerBlock !Int | number of threads per block to target for |
| OptimisationLevel !Int | level of optimisation to apply (1-4, default 4) |
| Target !Compute | compilation target, otherwise determined from context |
| FallbackStrategy !JITFallback | fallback strategy if matching cubin not found |
| GenerateDebugInfo | generate debug info (-g) (requires cuda >= 5.5) |
| GenerateLineInfo | generate line number information (-lineinfo) (requires cuda >= 5.5) |
| Verbose | verbose log messages (requires cuda >= 5.5) |
Results of online compilation

Instances
Querying module inhabitants
getPtr :: Module -> String -> IO (DevicePtr a, Int) Source
Return a global pointer, and size of the global (in bytes)
Loading and unloading modules
loadFile :: FilePath -> IO Module Source
Load the contents of the specified file (either a ptx or cubin file) to create a new module, and load that module into the current context.
loadData :: ByteString -> IO Module Source
Load the contents of the given image into a new module, and load that module into the current context. The image is (typically) the contents of a cubin or PTX file.
Note that the ByteString will be copied into a temporary staging area so
that it can be passed to C.
loadDataFromPtr :: Ptr Word8 -> IO Module Source
As loadData, but read the image data from the given pointer. The image is a
NULL-terminated sequence of bytes.
loadDataEx :: ByteString -> [JITOption] -> IO JITResult Source
Load the contents of the given image into a module with online compiler
options, and load the module into the current context. The image is
(typically) the contents of a cubin or PTX file. The actual attributes of the
compiled kernel can be probed using requires.
Note that the ByteString will be copied into a temporary staging area so
that it can be passed to C.
loadDataFromPtrEx :: Ptr Word8 -> [JITOption] -> IO JITResult Source
As loadDataEx, but read the image data from the given pointer. The image is
a NULL-terminated sequence of bytes.
