Struct SerialComm 

pub struct SerialComm;

Available on crate feature distributed only.

Single rank. All collectives are identity operations.

Trait Implementations

impl Clone for SerialComm

fn clone(&self) -> SerialComm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SerialComm

impl Debug for SerialComm

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

Formats the value using the given formatter.

impl Default for SerialComm

fn default() -> SerialComm

Returns the “default value” for a type.

impl RankComm for SerialComm

fn rank(&self) -> usize

Index of the calling rank, in 0..size().

fn size(&self) -> usize

Total number of ranks. Always a power of two for the distributed backend.

fn allgather_c64(&self, local: &[Complex64]) -> Vec<Complex64>

Concatenate every rank’s local block in ascending rank order.

fn allgather_f64(&self, local: &[f64]) -> Vec<f64>

f64 version of allgather_c64.

fn allgatherv_u64(&self, local: &[u64], _counts: &[usize]) -> Vec<u64>

Concatenate blocks of differing length in ascending rank order.

fn allreduce_sum_f64(&self, value: f64) -> f64

Sum a scalar across all ranks; every rank receives the total.

fn sendrecv_c64( &self, _partner: usize, send: &[Complex64], recv: &mut [Complex64], )

Exchange equal length amplitude blocks with partner.

fn barrier(&self)

Block until all ranks reach this point.

fn allgather_u64(&self, local: &[u64]) -> Vec<u64>

u64 version of allgather_c64.
