wea.jl

What is wea?

Giving the package a meaning - wea stands for Wrapped Exchange Array. If you want to share array-packed data with different processes, remote nodes or different language executables ( yes, that's the vision ), wea is aiming to be a lean, lightweight and convenient alternative to Protocol Buffers and Co.

It's inspired and adopted from Julia’s InterProcessCommunication WrappedArray in collaboration with @emmt.

If this sounds good to you, just give it a try.

Getting started

Install the package directly via

pkg> add https://github.com/casabre/wea.jl

until it is going to be registered.

Quick API guide

If you want to use a plain WrappedExchangeArray, just try

using wea

id = "/shm-id";
T = Float64;
dims = (10, 2);

wa = WrappedExchangeArray(id, T, dims);
wa[:] = ones(T, dims);

in order to create a shared memory segment.

Convenience functions

You can store any memory element within the Wrapped Exchange arrays. In order to reduce the setup hustle, you can utilize the following convenience modules.

Shared Exchange Array

In order to create a new shared memory segment, use the following snippet

using wea

key = "/shm-id";
T = Float64;
dims = (10, 2);

A = wea.SharedExchangeArray.create(key, T, dims)
A[:] = ones(T, dims)
id = wea.shmid(A)
B = wea.SharedExchangeArray.load(id; readonly=true)

Buffered Exchange Array

In order to share byte data via your favorite exchange protocol, you can use the following snippet.

using wea

T = Float32
dims = (3, 4, 5)
A = wea.BufferedExchangeArray.create(T, dims)
A[:] = ones(T, dims)
buf = wea.BufferedExchangeArray.get_exchange_buffer(A)
B = wea.BufferedExchangeArray.load(buf)
