Running an HPCC Systems cluster inside an Amazon Web Services (AWS) Elastic Cloud (EC2) allows you to instantiate and run HPCC Systems clusters of different sizes on the fly.

This is useful for:
• Proof-of-concept
• Experimentation
• Learning
• Leveraging the HPCC Systems platform without incurring cost of hardware and administration
• Create and use an HPCC Systems cluster immediately without purchasing and installing new hardware

You can create a small cluster for small tasks or larger clusters for larger jobs. This flexibility allows you to match cost and processing power to the job at hand.

Temporary EC2 nodes allow you to "rent" computing capacity without long term commitments. In this manner, you pay as you go instead of incurring large fixed costs at the start. Keep in mind that you should terminate any unneeded instances to avoid paying for computing time you don't need.

We are working with Amazon on a process to run an HPCC Systems cluster in an environment similar to Amazon Elastic Map Reduce (EMR). In addition, HPCC Systems is working on its own Enterprise Cloud offering, but it is not yet ready to be announced.

The following system requirements cover what is needed to support the HPCC Platform and ECL IDE included in the Community Edition.

The HPCC Systems Community Wiki includes information provided by the community covering best practices, tips, sample code and examples. The HPCC Systems Red Book also contains useful information to help users manage the transition between releases.

This tutorial provides a walk-through of the development process from beginning to end and is designed to be an introduction to working with data on HPCC, as well as give an introduction to Thor and Roxie. The Sample Data Files are required references for the tutorial.

Comrise, a HPCC Systems partner, has also made available a Chinese translated version of the ECL Programmers Guide (version 4.2.0.3rc).

ECL Playground is a tool hosted on an ESP server. A page runs in your browser, allowing you to access and execute self-contained ECL code on your HPCC system without the use of any other tools. The ECL Playground then shows you the results and the graph in your browser. The view is very similar to what the ECL IDE displays.
Listen to the ECL Playground Podcast and how it can be a helpful tool for developers.

ECL is the Enterprise Control Language designed specifically for huge data projects using the HPCC platform. Its extreme scalability comes from a design that allows you to leverage every query you create for re-use in subsequent queries as needed. To do this, ECL takes a dictionary approach to building queries wherein each ECL definition defines an Attribute. Each previously defined Attribute can then be used in succeeding ECL Attribute definitions as the language extends itself as you use it.

The ECL compiler now supports adding external resources to a Workunit using a manifest file. The manifest, in XML format, adds external resources such as XSLT transformations, or other objects to the archive before it is compiled and deployed to the server. This document demonstrates how to use this feature to visualize ECL job results using Google Chart Tools.
