    • Property Status changed from new to assigned
    • Property Severity changed from to minor
    • Property Cc mocavero added; francesca removed
    • Property Wp_comment changed from to The improvement of the hybrid coarse-grained approach (about 7% when the MPI scalability limit is reached) is not enough to justify the refactoring of the code. A final test by combining a tessellated approach with OpenMP will be performed and the ticket will be closed by the end of this year.
    • Property Summary changed from HPC-6_Silvia Development of the NEMO hybrid parallel version based on MPI/OpenMP to HPC-02(2017WP)_Francesca Development of the NEMO hybrid parallel version based on MPI/OpenMP
    • Property Priority changed from low to normal
    • Property Milestone changed from 2017 WP to 2018 WP
