HPCC Systems blog contributors are engineers and data scientists who for years have enabled LexisNexis customers to use big data to fulfill critical missions, gain competitive advantage, or unearth new discoveries. Check this blog regularly for insights into how HPCC Systems technology can put big data to work for your own organization.

We have prepared a Beta version of HPCC Systems® 6.0.0 to coincide with the HPCC Systems® Summit 2015.

The first stage in implementing QUANTILE will be to add it to the parser. This can sometimes highlight issues with the syntax and cause revisions to the design. In this case there were two technical issues integrating the syntax into the grammar. (If you are not interested in shift/reduce conflicts you may want to skip a few paragraphs and jump to the walkthrough of the changes.)

In this blog post I will show you how to use a big-data platform to build a fast prefix tree and why such a prefix tree can enable very fast edit-distance queries. In a follow-up post I offer different query examples, performance metrics, and code examples.

There is a lot to say about this intermediate release. 

As well as the many improvements and optimizations that make your use of the system easier and more efficient, HPCC Systems® now supports Ubuntu15.04 and CentoOS7.

Today at 19:00 UTC is the final pencils down date and also marks the opening of the GSoC final evaluation period.

All coding, unit tests and supporting documentation must now be complete. Both our GSoC students are on target to make this deadline. So how have the projects gone?

Here we are well in to August already. Our two HPCC Systems® interns are putting the finishing touches to their projects, completing documentation and submitting evaluations about their time working with us.

Implement the CONCORD algorithm into the HPCC Systems® Machine Learning Library

I want to share some additional information about 2 other students who joined our intern program this summer.

Michael Tierney and Evan Sheridan are graduates from Trinity College Dublin. Michael's undergraduate degree was in Physics and Astrophysics. He is also moving on to starting an MSc in High Performance Computing. Evan has just completed his degree in Theoretical Physics and will be starting his MSc in Theoretical Modelling at Kings College, London in September.

When adding new features to the system, or changing the code generator, the first step is often to write some ECL test cases. They have proved very useful for several reasons:

A lot has happened in the last year which gives us good reason to celebrate this anniversary with great enthusiasm. Here are some highlights, from the many to be proud of, that I want to share with you…

While this is the first year we have run a GSoC (Google Summer of Code) program, it is not the first year we have run an intern program.
