Fields

size: usize

Size of buffer (MB)

device_type: ArgDeviceType

Type of the device.

device_id: u16

Execute on CPU or GPU (See numactl -H and CUDA device list)

mem_type: ArgMemType

Memory type with which to allocate data.

mem_location: u16

Allocate memory on CPU or GPU (See numactl -H and CUDA device list)

page_type: ArgPageType

Page type with with to allocate memory

threads: Vec<usize>

Number of CPU threads

cpu_affinity: Option<PathBuf>

Path to CPU affinity map file for CPU workers

grid_sizes: Vec<u32>

The CUDA grid sizes to evaluate

block_sizes: Vec<u32>

The CUDA block sizes to evaluate

misalign_warp: Option<bool>

Don’t align warp-cooperative accesses to the tile size

By default, warp-cooperative accesses are aligned to the size of the tile, e.g., a value between 2 and 32. --misalign-warp deliberately misaligns such accesses by one array item.

loop_length: u32

Number of memory accesses in between cycle measurements

target_cycles: u64

Minimum number of clock cycles to measure before quitting (scaled by 10^6)

repeat: u32

Number of times to repeat benchmark

Trait Implementations

impl StructOpt for CmdBandwidth

fn clap<'a, 'b>() -> App<'a, 'b>

Returns clap::App corresponding to the struct.

fn from_clap(matches: &ArgMatches<'_>) -> Self

Builds the struct from clap::ArgMatches. It’s guaranteed to succeed if matches originates from an App generated by [StructOpt::clap] called on the same type, otherwise it must panic.

fn from_args() -> Self

Builds the struct from the command line arguments (std::env::args_os). Calls clap::Error::exit on failure, printing the error message and aborting the program.

fn from_args_safe() -> Result<Self, Error>

Builds the struct from the command line arguments (std::env::args_os). Unlike [StructOpt::from_args], returns clap::Error on failure instead of aborting the program, so calling .exit is up to you.

fn from_iter<I>(iter: I) -> Self where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making.
