A framework for out-of-core and parallel computing

At the core of Dagger.jl is a scheduler heavily inspired by Dask. It can run computations represented as directed-acyclic-graphs (DAGs) efficiently on many Julia worker processes and threads, as well as GPUs via DaggerGPU.jl.
The *DTable** has been moved out of this repository. You can now find it here.*
Installation
Dagger.jl can be installed using the Julia package manager. Enter the Pkg REPL mode by typing "]" in the Julia REPL and then run:
julia
pkg> add Dagger
Or, equivalently, install Dagger via the Pkg API:
julia
julia> import Pkg; Pkg.add("Dagger")
Usage
Once installed, the Dagger package can be loaded with using Dagger, or if
you want to use Dagger for distributed computing, it can be loaded as:
julia
using Distributed; addprocs() # Add one Julia worker per CPU core
using Dagger
You can run the following example to see how Dagger exposes easy parallelism:
```julia
This runs first:
a = Dagger.@spawn rand(100, 100)
These run in parallel:
b = Dagger.@spawn sum(a) c = Dagger.@spawn prod(a)
Finally, this runs:
wait(Dagger.@spawn println("b: ", b, ", c: ", c)) ```
Use Cases
Dagger can support a variety of use cases that benefit from easy, automatic parallelism, such as:
This isn't an exhaustive list of the use cases that Dagger supports. There are more examples in the docs, and more use cases examples are welcome (just file an issue or PR).
