PUMA Repository

The PUMA Repository is a collection of Pascal units for medical informatics. It contains reusable source code for a wide field of health-care application development. The code includes a support engine for the European Data Format (EDF and EDF+), converting functions for units of measurement and an HL7 engine. PUMA is compatible with Lazarus and Free Pascal. Some of the units also support other Pascal implementations including Delphi, winsoft Pocket Studio and other compilers.

Scimark for Delphi Lazarus Free Pascal

Benchmark for scientific and numerical computing. http://math.nist.gov/scimark Some years ago, someone converted the sources to delphi. The result of that convertion can be found here: https://code.google.com/p/scimark-delphi/ I found some issues and tried to contact the author. Without success. That's why I decided to start a new repository here. Patches are welcome!
