[−][src]Struct rustacuda::module::Module
A compiled CUDA module, loaded into a context.
Implementations
impl Module
[src]
pub fn load_from_file(filename: &CStr) -> CudaResult<Module>
[src]
Load a module from the given file name into the current context.
The given file should be either a cubin file, a ptx file, or a fatbin file such as
those produced by nvcc
.
Example
use rustacuda::module::Module; use std::ffi::CString; let filename = CString::new("./resources/add.ptx")?; let module = Module::load_from_file(&filename)?;
pub fn load_from_string(image: &CStr) -> CudaResult<Module>
[src]
Load a module from a CStr.
This is useful in combination with include_str!
, to include the device code into the
compiled executable.
The given CStr must contain the bytes of a cubin file, a ptx file or a fatbin file such as
those produced by nvcc
.
Example
use rustacuda::module::Module; use std::ffi::CString; let image = CString::new(include_str!("../resources/add.ptx"))?; let module = Module::load_from_string(&image)?;
pub fn get_global<'a, T: DeviceCopy>(
&'a self,
name: &CStr
) -> CudaResult<Symbol<'a, T>>
[src]
&'a self,
name: &CStr
) -> CudaResult<Symbol<'a, T>>
Get a reference to a global symbol, which can then be copied to/from.
Panics:
This function panics if the size of the symbol is not the same as the mem::sizeof<T>()
.
Examples
use rustacuda::module::Module; use std::ffi::CString; let ptx = CString::new(include_str!("../resources/add.ptx"))?; let module = Module::load_from_string(&ptx)?; let name = CString::new("my_constant")?; let symbol = module.get_global::<u32>(&name)?; let mut host_const = 0; symbol.copy_to(&mut host_const)?; assert_eq!(314, host_const);
pub fn get_function<'a>(&'a self, name: &CStr) -> CudaResult<Function<'a>>
[src]
Get a reference to a kernel function which can then be launched.
Examples
use rustacuda::module::Module; use std::ffi::CString; let ptx = CString::new(include_str!("../resources/add.ptx"))?; let module = Module::load_from_string(&ptx)?; let name = CString::new("sum")?; let function = module.get_function(&name)?;
pub fn drop(module: Module) -> DropResult<Module>
[src]
Destroy a Module
, returning an error.
Destroying a module can return errors from previous asynchronous work. This function destroys the given module and returns the error and the un-destroyed module on failure.
Example
use rustacuda::module::Module; use std::ffi::CString; let ptx = CString::new(include_str!("../resources/add.ptx"))?; let module = Module::load_from_string(&ptx)?; match Module::drop(module) { Ok(()) => println!("Successfully destroyed"), Err((e, module)) => { println!("Failed to destroy module: {:?}", e); // Do something with module }, }
