Workhorse

Workhorse is a distributed computing server. It serves up problems and solvers and accepts solutions. It is currently intended for running bandwidth or processor intensive operations on the client side of a web application, but can also be useful for serving up jobs to server clusters.

Keep in mind this stuff is in early development. Please let me know if you have issues or patches. Happy solving :)

Usage

For usage, see examples. For more detailed use cases, see tests.

Dependencies

For dependencies, see package.json

Run All Tests

expresso

Run Individual Tests

expresso <test path>

e.g. expresso test/workhorse.js

Data Store

Workhorse holds a registry of problems and their solutions in the form of key/value pairs. This registry uses a key/value data store, which is the main argument to the workhorse create function.

If you do not pass in a datastore, an in-memory data store will be used. All tests use the in-memory key/value store provided with the keys library.

You may use any of the keys supported database management systems or roll your own data store, implementing the set, has, and get actions.

A CouchDB data store is also being developed as part of the workhorse library and supports the aforementioned actions. To use the couchdb datastore, create a couch datastore and initialize the workhorse with it:

var workhorse = require('workhorse'),
    couch_store = require('workhorse/lib/datastores/couchdb');

var datastore = couch_store.create('localhost', 5984, 'my_workhorse_couch');
var wh = workhorse.create(datastore);

Server

Workhorse provides an HTTP server for GETting problems to solve, GETting solvers, and POSTing solutions in a RESTful way. POSTing problems will be supported in the near future, as well.

Once a problem has been solved, the JSON returned from GETting the problem will include the solution. The solution will also be POSTed to the URI with which it was registered.

Something went wrong with that request. Please try again.
