Struct ispc_rt::exec::Parallel

pub struct Parallel { /* fields omitted */ }

A multithreaded execution environment for the tasks launched in ISPC

Methods

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: ISPCTaskFn,     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.
