Abstract:

The BTeV trigger performs sophisticated computations using
large ensembles of FPGAs, DSPs, and conventional
microprocessors. This system will have between 5,000 and
10,000 computing elements and many networks and data
switches. While much attention has been devoted to developing
efficient algorithms, the need for fault-tolerant, fault-adaptive,
and flexible techniques and software to manage this huge
computing platform has been identified as one of the most
challenging aspects of this project. We describe the problem
and offer an approach to solving it based on a distributed,
hierarchical fault management system.
