Section: Software

CALU for multicore architectures

Participant : Laura GRIGORI [correspondant] .

The communication avoiding algorithms are implemented in the form of a portable library. In its current form, this library is designed for multicore architectures and uses a hybrid scheduling technique that exploits well the data locality and can adapt to dynamic changes in the machine. The library will be publicly available since February 2012.

Version: 1.0
