PVFS2-TracingTracing the PVFS2 Environment
Project Goals:
With parallel input/output from parallel programs it is difficult to get an insight into the server behavior that is triggered by I/O calls in the program. Our project will enhance the MPICH2 tool Jumpshot with additional functionality to visualize server activities from the PVFS2 environment. In order to get the necessary information we will extend PVFS2 by means to write trace information to files. In addition to the regular client program trace we can generate a server trace and merge it with the client trace. Connecting corresponding events allows us to visualize disk read/write operations in dependcy of their corresponding MPI-IO read/write calls.

Organic Computing in Distributed Systems
Project Goals:
Our intention is to establish a conceptual framework of organic computing which is suitable for the practical design of organic systems, i.e. systems with so called self-x properties, in Information Technology. Dynamic models of brain functions give an idea of the organizational principles through which nervous systems solve complex information processing. Therefore, one of our goals is to form these principles into general concepts of information processing within the framework of organic computing. Another goal is to achieve self-x properties in distributed computer systems focusing on large-scale ad-hoc grid computing, which will also provide a feasibility study for our developed concepts.
