    GnuCOBOL

    GnuCOBOL

    A free COBOL compiler

    GnuCOBOL (formerly OpenCOBOL) is a free, modern COBOL compiler. GnuCOBOL implements a substantial part of the COBOL 85, X/Open COBOL and newer ISO COBOL standards (2002, 2014, 2023), as well as many extensions included in other COBOL compilers (IBM COBOL, MicroFocus COBOL, ACUCOBOL-GT and others). GnuCOBOL translates COBOL into C and internally compiles the translated code using a native C compiler. Build COBOL programs on various platforms, including GNU/Linux, Unix, Mac OS X, and...

    NetFireCoRE

    NetFireCoRE

    Network Firewall Linux Kernel Module with Conflict Resolution Engine

    We implement an open source conflict resolution framework that consists of a user-space C application that automatically resolves firewall rules anomalies, and b) a generic tree (called policy tree), implemented as a Linux kernel module which maintains the resolved firewall rules and enables the necessary hooks to netfilter for matching incoming (or outgoing) network packets. Tree-based data structures offer improved efficiency compared to traditional access control lists (e.g. iptables or nftable maps), especially for large systems with a huge number of rules. ...

    drvq

    dimensionality-recursive vector quantization

    drvq is a C++ library implementation of dimensionality-recursive vector quantization, a fast vector quantization method in high-dimensional Euclidean spaces under arbitrary data distributions. It is an approximation of k-means that is practically constant in data size and applies to arbitrarily high dimensions but can only scale to a few thousands of centroids.

    Semantic query optimization (SQO) is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance. We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude. This gain in performance is due to a combination of novel methods that lower the complexity in practical situations significantly.

    X-RT

    X-RT: A portable multiprocessor real-time scheduling framework

    This project contains the material discussed in my PhD dissertation, entitled "Hardware/Software Design of Dynamic Real-Time Schedulers for Embedded Multiprocessor Systems." The source code is available in the SVN repository: https://sourceforge.net/p/xrt/code/6/tree/trunk/ and consists in two folders: 1) /X-RT : A portable multiprocessor scheduling framework supporting scheduling periodic real-time tasks according to the G-EDF (Global Earliest Deadline First) scheduling platform. Current version supports major POSIX systems (Linux, QNX). 2) Hardware_GEDF_Scheduler: is a hardware implementation in VHDL (targeting FPGAs) of the G-EDF multiprocessor scheduling policy.
