Struct ispc::exec::Parallel

pub struct Parallel { /* private fields */ }

A multithreaded execution environment for the tasks launched in ISPC

Implementations

impl Parallel

pub fn new() -> Arc<Parallel>

Create a parallel task execution environment that will use num_cpus threads to run tasks.

pub fn oversubscribed(oversubscribe: f32) -> Arc<Parallel>

Create an oversubscribued parallel task execution environment that will use oversubscribe * num_cpus threads to run tasks.

Trait Implementations

impl TaskSystem for Parallel

unsafe fn alloc( &self, handle_ptr: *mut *mut c_void, size: i64, align: i32 ) -> *mut c_void

Alloc is called when memory must be allocated to store parameters to pass to a task and must return a pointer to an allocation of size bytes aligned to align.

unsafe fn launch( &self, handle_ptr: *mut *mut c_void, f: extern "C" fn(_: *mut c_void, _: i32, _: i32, _: i32, _: i32, _: i32, _: i32, _: i32, _: i32, _: i32, _: i32), data: *mut c_void, count0: i32, count1: i32, count2: i32 )

Launch is called when a new group of tasks is being launched and should schedule them to be executed in some way.

unsafe fn sync(&self, handle: *mut c_void)

Synchronize an execution context with the tasks it’s launched. Use handle to determine the task context that’s being synchronized.
