Libraries and Algorithms: Dense LU Factorization

CharmLU is a high-performance dense LU solver library that is highly scalable and follows the HPCC specification. In 2011, it won an HPCC award for best performance as part of a set of benchmarks.

The implementation is designed to be composable with user-level application code.

In addition, the chare array mapping flexibility built into Charm++ helps to minimize coupling with control flow code and allows the user or library developer to explore various mappings of block to processor easily.
