Software development
» A Garbage Collector
(for C and C++) - can be used as a garbage collecting replacement for C malloc
or C++ new, allowing users memory as they normally would, without explicitly
deallocating memory that is no longer useful.
» Linux

(Itanium Processor Family, IPF) architecture, intended primarily for application-
and kernel-level software development.
» HP Java Programming Toolkits -
source code for several Java analysis tools. The Javafe front end is an extensible parser and type checker for Java. The HP Extended Static Checker for Java (ESC/Java) is a tool that attempts to find common run-time errors in Java programs by static analysis of the program text. Houdini is a tool that infers the program annotations used by ESC/Java. The HP Race Condition Checker for Java (RCC/Java) identifies potential race conditions in multithreaded Java code statically. The HP Research ESC/Java Synchronization Checker (Calvin) is a static checker for multithreaded Java programs that can check invariants as well as identify potential race conditions. Simplify is the automated theorem prover used by ESC/Java, Houdini, and Calvin.
