flux-broker(1)¶
SYNOPSIS¶
flux-broker [OPTIONS] [initial-program [args...]]
DESCRIPTION¶
flux-broker(1) is a distributed message broker daemon that provides communications services within a Flux instance. It may be launched as a parallel program under Flux or other resource managers that support PMI.
Resource manager services are implemented as dynamically loadable modules.
Brokers within a Flux instance are interconnected using ZeroMQ sockets, and each is assigned a rank from 0 to size - 1. The rank 0 node is the root of a tree-based overlay network. This network may be accessed by Flux commands and modules using Flux API services.
A logging service aggregates Flux log messages across the instance and emits them to a configured destination on rank 0.
After its overlay network has completed wire-up, flux-broker(1) starts the initial program on rank 0. If none is specified on the broker command line, an interactive shell is launched.
OPTIONS¶

Summarize available options.
- -v, --verbose
Be annoyingly chatty.
- -S, --setattr=ATTR=VAL
Set initial value for broker attribute.
- -c, --conf-path==PATH
Set the PATH to broker configuration. If PATH is a directory, then read all TOML files from that directory. If PATH is a file, then load configuration as JSON if the file extension is
.json, otherwise load the file as TOML.
