Camure

High-performance 1-to-many communication and synchronization primitives using UDP multicast.

This crates provides a set of communication and synchronization primitives similar to the collective communication routines found in MPI. In contrast to MPI, this crates allows for more flexible communication patterns without sacrificing performance and is designed to be used in mid-sized distributed systems. The underlying protocol is session based which allows nodes to join and leave at any time. One node explicitly takes over the role of the session coordinator and is responsible for creating the session. All other nodes must join the session as a member.

For more information on how to establish and join sessions, see the [session] module.

Groups

Each session is divided into multiple groups that operate independently of each other. Groups are always created by the coordinator and must be explicitly joined by members. There are currently two different types of groups.

Barrier

Broadcast

Debugging

If you encounter a lot of timeouts, hangs, or other issues, you can enable logging to get more information about what is happening. This crate uses the log crate for logging. So, choose a logging implementation according to their documentation and make sure to set the log level to trace for this crate. In order to avoid any overhead caused by logging ensure that the compile time filter is set to debug or higher (see Compile Time Filters for more information).

Future Work

• Improve Member Management: Currrently, the chunk allocation strategy is suboptimal and can be improved to increase performance.
