    UFTP

    Encrypted UDP based FTP with multicast

    UFTP is an encrypted multicast file transfer program, designed to securely, reliably, and efficiently transfer files to multiple receivers simultaneously. This is useful for distributing large files to a large number of receivers, and is especially useful for data distribution over a satellite link (with two way communication), where the inherent delay makes any TCP based communication highly inefficient. The multicast encryption scheme is based on TLS with extensions to allow multiple receivers to share a common key. UFTP also has the capability to communicate over disjoint networks separated by one or more firewalls (NAT traversal) and without full end-to-end multicast capability (multicast tunneling) through the use of a UFTP proxy server. These proxies also provide scalability by aggregating responses from a group of receivers.

    PingMon

    PingMon

    Ping monitoring tool (32 Bit) for any Windows System (x86 or x64)

    This is a ping monitoring tool for almost any Windows System (tested on Win 98*-10 and Server 2003-2016) and it runs on Linux via WINE either*. No .NET is needed. This is a 32bit app and will work on x86 and x64 architectures. Adjustable and easy to use. And you can choose if you want it to create RAW packets instead of using Windows icmp.dll resources. Usage examples: PingMon.exe HOST1 HOST2 Will open 2 instances of PingMon and start pinging immediately. Since Windows shortcuts are limited, there also is a way to run a batch file like this: start PingMon.exe HOST 1 start PingMon.exe HOST 2 ... start PingMon.exe HOST 33 The numbers are used for positioning. Version 0.3 and later contain another tool, PingHist, to visualize log files again: PingHist.exe LOGFILE Will visualize file LOGFILE. *) Versions 0.2 and higher don't run on non-NT systems. This is due to elevation detections. So, on Windows 98 you will have to run 0.1 versions No further dev.

    BMDFM

    BMDFM

    Binary Modular DataFlow Machine (BMDFM)

    Binary Modular DataFlow Machine (BMDFM) is a software package that enables running an application in parallel on shared memory symmetric multiprocessing (SMP) computers using the multiple processors to speed up the execution of single applications. BMDFM automatically identifies and exploits parallelism due to the static and mainly dynamic scheduling of the dataflow instruction sequences derived from the formerly sequential program. The BMDFM dynamic scheduling subsystem performs a symmetric multiprocessing (SMP) emulation of a tagged-token dataflow machine to provide the transparent dataflow semantics for the applications. No directives for parallel execution are needed. More info: http://www.bmdfm.com
