New URL for NEMO forge!   http://forge.nemo-ocean.eu

Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

    38 '''          Motivation:''' Improve NEMO scalability. [[BR]]  '''          Status:''' Partly closed. The feasibility study related to the introduction of the PETSc library  has been concluded. From this study it has been deduced that a  consistent manpower is needed. Since this effort is not available using  the currently funded projects, the activity related to the introduction  of PETSc into the NEMO code will be sustained when new project funds  will be achieved. A report on the results of this study is  available and will be provided at the November merge party.[[BR]]  '''          Main tasks:'''[[BR]]  * Introduction of a new software layer in the NEMO stack software exploiting numerical optimized and parallel libraries such as  pBLAS, ScaLAPACK and PETSc. [[BR]]  * Continuation of the implementation of hybrid parallel approach based on the functional parallelism for the tracers, momentum equations and 3D domain decomposition.[[BR]]  * Test performances of XIOS on CMCC architectures[[BR]] '''System Reviewer:''' [[BR]]  '''          Deadline:'''  2013[[BR]]  '''          Priority: '''Medium [[BR]]  '''          Principal investigator:''' Italo Epicoco [[BR]]
