Lightweight, zero dependencies and simple Java asynchronous non blocking distributed computing
library where devices can enter or leave at any time, does not require any extra configuration on
machines and supports remote class and native library loading
## Features
- Distributed and parallel master worker computing
- Supports remote class loading
- Supports remote native library loading (.so, .dll)
- Devices can enter or leave computation at any time
- Fault tolerance mechanism via exceptions and timeouts
- ~~Provides runtime conversion of java class file to Android dex format~~
- Modular architecture
- No configuration required

## Requirements
This library requires some software to provide access to resources (class files, jar packages and native libraries) if any is required by clients, like **Lighttp**.
## Properties
```bash
codebase.url
```
Defines the URL that identifies the location of class and jar resources.
Default value is "file:"
Required for remote class loading
Server only
[//]: # (Module: ...crowd.discovery Class: CodebaseUtils)
```bash
codebase.root
```
Points to root path of resources.
Default value is some temporary directory path
Required for remote resource loading
Server only
[//]: # (Module: ...crowd.discovery Class: CodebaseUtils)
```
lib.url
```
Defines the URL that identifies the location native library resources.
Default value is "file:"
Required for remote native library loading
Server only
[//]: # (Module: ...crowd.discovery Class: CodebaseUtils)
Show All
```
codebase.url.separator
```
Default value is: " "
[//]: # (Module: ...crowd.discovery Class: URLUtils)
```
classloader.custom
```
Tells application to use a custom classloader defined in "classloader" property below.
Default value is: "False"
```
classloader
```
This property defines the canonical class name of alternative classloader to be used if "classloader.custom" property is true.
~~Default value is "com.github.lbovolini.crowd.android.classloader.AndroidRemoteClassLoader"~~
~~Optional, use only if alternative classloader, that is not AndroidRemoteClassLoader, is required.~~
Client only
[//]: # (Module: ...crowd.classloader Class: RemoteClassLoaderService)
```
cache
```
See: https://docs.oracle.com/javase/7/docs/api/java/net/URLConnection.html#setUseCaches(boolean)
