Enum renoir::config::RuntimeConfig
source · pub enum RuntimeConfig {
Local(LocalConfig),
Remote(RemoteConfig),
}
Expand description
The runtime configuration of the environment,
This configuration selects which runtime to use for this execution. The runtime is either local (i.e. parallelism is achieved only using threads), or remote (i.e. using both threads locally and remote workers).
In a remote execution the current binary is copied using scp to a remote host and then executed using ssh. The configuration of the remote environment should be specified via a TOML configuration file.
§Local environment
let config = RuntimeConfig::local(2).unwrap();
let env = StreamContext::new(config);
§Remote environment
let config = r#"
[[host]]
address = "host1"
base_port = 9500
num_cores = 16
[[host]]
address = "host2"
base_port = 9500
num_cores = 24
"#;
let mut file = File::create("config.toml").unwrap();
file.write_all(config.as_bytes());
let config = RuntimeConfig::remote("config.toml").expect("cannot read config file");
let env = StreamContext::new(config);
§From command line arguments
This reads from std::env::args()
and reads the most common options (--local
, --remote
,
--verbose
). All the unparsed options will be returned into args
. You can use --help
to see
their docs.
let (config, args) = RuntimeConfig::from_args();
let env = StreamContext::new(config);
Variants§
Local(LocalConfig)
Use only local threads.
Remote(RemoteConfig)
Use both local threads and remote workers.
Implementations§
source§impl RuntimeConfig
impl RuntimeConfig
sourcepub fn from_args() -> (RuntimeConfig, Vec<String>)
pub fn from_args() -> (RuntimeConfig, Vec<String>)
Build the configuration from the specified args list.
sourcepub fn local(parallelism: CoordUInt) -> Result<RuntimeConfig, ConfigError>
pub fn local(parallelism: CoordUInt) -> Result<RuntimeConfig, ConfigError>
Local environment that avoid using the network and runs concurrently using only threads.
sourcepub fn remote<P: AsRef<Path>>(
toml_path: P
) -> Result<RuntimeConfig, ConfigError>
pub fn remote<P: AsRef<Path>>( toml_path: P ) -> Result<RuntimeConfig, ConfigError>
Remote environment based on the provided configuration file.
The behaviour of this changes if this process is the “runner” process (ie the one that will execute via ssh the other workers) or a worker process. If it’s the runner, the configuration file is read. If it’s a worker, the configuration is read directly from the environment variable and not from the file (remote hosts may not have the configuration file).
sourcepub fn spawn_remote_workers(&self)
pub fn spawn_remote_workers(&self)
Spawn the remote workers via SSH and exit if this is the process that should spawn. If this is already a spawned process nothing is done.
pub fn host_id(&self) -> Option<CoordUInt>
