Introduction
Kepler is used for the orchestration of the ITM codes and HPC2K has been designed to generate easily GRID or HPC actors. These actors are then used in a workflow as any other local code. The remote data access is generated automatically.
I-Objective
II-Preliminary requirements
III-Preliminary requirements
GRID/HPC:
Physic code = jobs on GRID or HPC
Actors for easy jobs submission (using RAS actors and RAS/Vine infrastructure)
Current implementation requires an explicit data transfer (files)
Remote UAL: data access for jobs running on GRID & HPC
HPC2K tool:
Easy one click creation of Fortran or C GRID/HPC jobs and integration in KEPLER (actor)
Same user code could be a local actor, a Web service or a GRID/HPC job
WORKING ON A GRID ENVIRONMENT:
Preliminary settings to use GRID infrastructure :
Obtain a Digital Certificate
Account on a User Interface machine
Register with an appropriate Virtual Organization.
GENERATING A TEMPORARY CERTIFICATE:
The user needs to generate a temporary certificate stored under his home directory and called proxy.
The user can use a predefined workflow to create it :
Certificate : usercert.pem
Key : userkey.pem
VO : euforia for example
V-Workflow with actors generated by HPC2K
VI-HPC2K tool
IV-Current use of RAS actors
Project, actor names
& others parameters
Arguments
GRID or HPC infrastructure
Kepler & UAL
A high number of inputs has to be specified by the user.
The user has to integrate by himself the access to ITM database if needed.
I/O are limited to I/O (Cpos) of simulation codes
ITM data access based on the UAL
