NationMaster - Encyclopedia: Aard

Aard (Dutch for "Earth") is a programming tool to check memory use for C++ programs. It is written by Steve Reiss, who names his programs after living systems.

Aard tracks the state of each byte of memory in the heap and the stack. The state can be one of Undefined, Uninitialised, Free or Set. The program can detect invalid transitions (i.e. attempting to set or use undefined or free storage or attempting to access uninitialised storage).

In addition, the program keeps track of heap use through malloc and free and at the end of the run reports memory blocks that were not freed and that are not accessible (i.e. memory leaks).

The tool works using a spliced-in shared library on SPARCs running C++ 3.0.1 under SunOS 4.X.

	AARD's food crops research activities are organized by commodities and problem areas: rice; palawija (non-rice food crops: maize, sorghum, soybean, peanut, mungbean, pigeonpea, cassava, and sweet potato); wheat; problem soils; farming systems; water management; and post-harvest technology and quality (Crifc 1986).
	AARD institutes occasionally hold training courses for extension personnel, and scientists are sometimes invited to make presentations to courses held at the ministry's in-service training centers.
	AARD publications must be given away free of charge to qualified individuals (such as extension personnel) and institutions (such as university libraries).
