SHMU - HPC

From LACE report february 2010:

Increased number of vertical levels would be desirable, but with current domain and resolution IBM machine is on the edge of CPU limits (it has not been upgraded since February 2004)

The IBM Power® 750 Express™ server delivers the outstanding performance of the POWER7™ processor. The performance, capacity, energy efficiency and virtualization capabilities of the Power 750 Express make it an ideal consolidation, database or multiapplication server.

NEW HPC on

CANARI (done)Two ways of data for OBSOUL 1) prepared from MySQL localy on SHMU2) OPLACE – SYNOP, TEMP

LACE Observation Monitor (instaled and prepared for

use)

Local OBSOUL file include 33 Automatic Weather Stations (AWS)

First outputs from VERAL in

Some test with Automatic Hydrological Stations (1 month period 201006)Mean difference Blue <1°C < green<3°C < yellow < 5°C< red

future plans in assimilation

CANARI (35T1 or 36T1???) to parsuite [very close to finish] => operative

soon:- compute B matrix (ensemble or SNMC ???)- parsuite with 3D Var- quality tests for automatic station for use in hi-resolution models (meteo.,hydro.,road maintenance service,…)

LONG TERM PLAN- radar assimilation

Thank you for your attention
