Europe's biggestsoftware conference will take place March 26 through April 3 in Saarbruecken, Germany.

The ETAPS conference will focus on security and reliability of software systems. Researchers from all over the world will come to the event to participate in the discussion.

The conference takes place against a backdrop of ever increasing complexity in software systems. That complexity is reaching levels that challenge even the most knowledgeable experts.

Because programs often have been growing for years, they have become more accident-prone as they get bigger. "A lot of research is required so that companies get a better handle on the complexity of systems," said Reinhard Wilhelm, the Saarbruecken IT professor who chairs theconference.
