COUFLESS 2014 - International Workshop COmplex faUlts and Failures in LargE Software Systems (COUFLESS)

The theory of software debugging is stuck at the notion of a software system as a single program with input data. Debugging distributed components involves correlating messages that these components send to one another. Mandelbug debugging is difficult due to the lack of understanding of interactions among different components of applications. Another ramification of the software increasing complexity is the new challenge of latency tail tolerance where a request will be decomposed of hundreds of request to compose of the final answer the end-user requests. Under these complex environments, there is a large variability on the response time. This large variability is causing thousands of disruptions per second (scale of milliseconds) according to Google results. These types of phenomena can be also considered to Mandelbug-based anomalies.
The topic of this workshop can be addressed from multiple angles and thus it requires a multidisciplinary audience. Performance is a key challenge in building large distributed applications since their predictability is inherently difficult due to Mandelbugs, complex faults and failures that require a uniform set of models that link the behavior of applications with data constraints and the properties of data management software.
