Enum mpi::Threading

pub enum Threading {
    Single,
    Funneled,
    Serialized,
    Multiple,
}

Describes the various levels of multithreading that can be supported by an MPI library.

Examples

See examples/init_with_threading.rs

Standard section(s)

12.4.3

Variants

Single

All processes partaking in the computation are single-threaded.

Funneled

Processes may be multi-threaded, but MPI functions will only ever be called from the main thread.

Serialized

Processes may be multi-threaded, but calls to MPI functions will not be made concurrently. The user is responsible for serializing the calls.

Multiple

Processes may be multi-threaded with no restrictions on the use of MPI functions from the threads.

Trait Implementations

impl Clone for Threading

fn clone(&self) -> Threading

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Threading

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<i32> for Threading

fn from(i: c_int) -> Threading

Converts to this type from the input type.

impl Ord for Threading

fn cmp(&self, other: &Threading) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self where
    Self: PartialOrd<Self>, 

Restrict a value to a certain interval.

impl PartialEq<Threading> for Threading

fn eq(&self, other: &Threading) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Threading> for Threading

fn partial_cmp(&self, other: &Threading) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
