===Debugging and monitoring===

Developing and debugging parallel programs on a cluster requires parallel language primitives and suitable tools such as those discussed by the ''High Performance Debugging Forum'' (HPDF) which resulted in the HPD specifications.<ref name="Prabhu"/><ref name=iosp>{{cite journal|last1=Francioni|first1=Joan M.|last2=Pancake|first2=Cherri M.|author-link2=Cherri M.

The [[University of California, Berkeley]] ''Network of Workstations'' (NOW) system gathers cluster data and stores them in a database, while a system such as PARMON, developed in India, allows visually observing and managing large clusters.<ref name="Prabhu"/>
