Deadline: December 2014
Priority: MEDIUM-LONG
Depends on:
Principal Investigator : S. Mocavero

CMCC-2 - Scalability with mapping strategies

Motivation: Improve NEMO scalability
Status : New
Main tasks : use of suitable mapping strategies to optimize the code performance
Science Reviewer:

Science Reviewer:
System Reviewer:
Deadline: September 2014
Priority: HIGH
Depends on: XIOS
Principal Investigator : I. Epicoco

CMCC-4 - Evaluation of dynamic allocation strategy

Motivation: Evaluate the performances introduced by the work space allocation (wrk_alloc / wrk_dealloc) instead of the automatic allocation
Status : new
Main tasks : compare the wkr_alloc / wrk_dealloc version with the automatic allocation
