Open Source C Mainframe Software

Hercules is an open source software implementation of the mainframe System/370 and ESA/390 architectures, in addition to the new 64-bit z/Architecture. Hercules runs under Linux, Windows, Solaris, FreeBSD, and Mac OS X. Hercules was created by Roger Bowler and is maintained by Jay Maynard. Jan Jaeger designed and implemented many of the advanced features of Hercules, including dynamic reconfiguration, integrated console, interpretive execution and z/Architecture support. A dedicated crew of programmers is constantly at work implementing new features and fixing bugs.

This project has been split and moved to: https://github.com/besm6/simh - BESM-6 simulator https://github.com/besm6/dispak - DISPAK simulator https://github.com/besm6/besm6-archive - disk images https://besm6.github.io/ - examples, DISPAK sources and KRAB sources

Set of programs and scripts that will allow to improve the usage of CPUSET. It includes a "jail" for users to just use on cpuset and sets and permissions management. (See web for more information)

CDs can be thought of as a mechanism to support fine-grained, hierarchical, application-directed, uncoordinated checkpoint and restore. Containment Domains (CDs) were created to allow an application to recover in the face of various types of component failures, including hard (e.g. persistent) and soft (e.g. transient) hardware failures, transient software failures, and complete node failures.

It can help you typing less code to build a PIC program.

FreeSP is an infrastructure for programming platform-independend online signal processing applications. Ports to specific platforms (like DSPs and microcontrollers) are made by simply exchanging the freeSP System-module.

zpmd for z/Linux running under z/VM on IBM mainframe is a z/VM Performance Monitor Daemon. It processes and gathers data from DCSS used by Monitor System Service (*MONITOR). Records are written to MySQL database.
