Grid Application Middleware: 

Grid Application Middleware Why grid application middleware Enable applications to run on grid(s) Make easier Example grid application middleware development/testing Ninf-G (AIST, Japan) Nimrod/G (Monash University, Australia) Mpich-Gx (KISTI, Korea)

Ninf-G http://ninf.apgrid.org: 

Ninf-G http://ninf.apgrid.org Developed by AIST, Japan Support GridRPC model which will be a GGF standard Integrated to NMI release 8 (first non-US software in NMI) Ninf roll for Rocks 4.x is also available 3 applications ran in PRAGMA grid and 1 ran on GIN testbed (multi-grids) TDDFT QM/MD FMO Achieved long runs (1 week ~ 50 days) Improved fault-tolerance (papers) - hang Simplified deployment procedures Speed-up development cycles

Nimrod/G http://ninf.apgrid.org: 

Nimrod/G http://ninf.apgrid.org Developed by Monash University, Australia Supports large scale parameter sweeps on Grid infrastructure Easy user interface - portal 3 applications ran in PRAGMA grid and 1 will run in GIN testbed (multi-grids) Savanah climate simulation (MU) GAMESS/APBS (UZurich) Siesta (UZurich) Achieved long runs (90 different scenarios of 6 weeks each Improved fault-tolerance (innovate time_step) Speed-up enhancements

Mpich-Gxhttp://www.moredream.org/mpich.htm: 

Mpich-Gx http://www.moredream.org/mpich.htm KISTI, Korea Grid-enabled MPI, support Private IP Fault tolerance Application run on KGrid MM5 Climate simulation CICESE, Mexico

Infrastructure Middleware: 

Infrastructure Middleware Why grid infrastructure middleware Provide grid services Make grid easier to use and manage Example grid infrastructure middleware Grid file system Gfarm (AIST, Japan) Grid monitoring system SCMSWeb (Kasetsart University, Thailand) Grid accounting system MOGAS (Nanyang Technological University, Singapore)

Gfarm – Grid Virtual File Systemhttp://datafarm.apgrid.org/:

Lessons Learned: 

Lessons Learned Differences among grids Organization structures Authentication (GSI, VOMS) Job submission (GRAM, Gridftp) Software stacks Takes a lot of learning to understand Takes a lot of work to interoperate Resolved some problems (GSI-VOM, GT2-GT4) Stimulated new initiatives (Cross grid monitoring) Learned some from each other (Community Software Area) Many more still yet to work on (File sharing, easy user access, direction and standards)

Forward: 

Forward More resources More computational resources GUCAS, China; UMC, USA; … Add data resources (geo, atro, bio, …) Add sensor network resources NCHC, Taiwan; BU, USA; … More applications Geoscience (Mian Liu, Huai Zhang) More and better grid middleware Credential management systems (SDSC, USA; Naregi, Japan) Portals (NCHC, Taiwan; QUT, Australia; …) Meta-schedulers (AIST, Japan; IHPC, Singapore; …) More grids interoperation More grids More applications More collaboration on grid technology research and development
