Software engineers make use of many tools
in the development of software.
Tool: CheckStyle, FindBugs, lint, Valgrind,

Some of software works in more than one machines and
such distributed software can handle large amount of data or
works in severe environments because such software make
use of much computer resources. In this paper we call a
server works in a cluster as ‘instance.’
for example, in search engines or distributed databases, the
fractions of indexes are stored in multiple instances.Such
system need a component to merge the query results before
the return the results to the users.
