Struct ispc::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

pub 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.

pub 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.

pub 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.
