GRID & HPC Actor generator
HPC2K GRID & HPC Actor generator B.Guillerminet, Magalie Soca ISIP Task T8 Thanks to the contributors to the EUFORIA project and European Task Force on Integrated Tokamak Modelling Activity Links: & 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 VIII-Generated actor VII-Example of parameters FORTRAN subroutine + Make +HPC2K RAS server: IX-Code parameters GRID or HPC: Normal or Openmpi: X-Status & documentation HPC2K available for GRID & HPC Remote UAL is the 4.07c version RAS server (poznan, gateway) HPC2K user’s guide (~guillerm/public/LISBON/docs/HPC2K user’s guide.pdf) Workflows and examples on ~guillerm/public/LISBON/examples Same user code could be a local actor, a Web service or a GRID/HPC job
