ALICE-USA Commitments

• OSC is commited now to getting NSF funding to
  Acquire this Level of Support.
• LBL (NERSC) UH are DOE funded and Commited to
  supplying these resources contingent upon DOEs
  approval of the ALICE-USA EMCAL project.
• All three institutions CONTINUE TO SUPPORT THE
  DATA CHALLENGES
• DOE is Currently well into the decision process
  regarding budgeting the Construction of EMCAL by
  ALICE-USA for ALICE. Funding to support
  Prototyping has been provided

6
ALICE-USA Data Challenge Support

• Since 2002, ALICE-USA has provided significant
  support for the Data Challenges.
• Most recently (2004) ALICE-USA supplied 14 (106
  MSI2k-Hours) of the total (755 MSI2k-Hours) CPU
  and external storage capacity.
• For 2005-2007 ALICE-USA intends to supply a
  similar fraction from existing commitments.

7
ALICE-USA Grid Middleware

• We will support ALICEs needs with whatever
  Middleware is consistent with them
• As Well As what is consistent with our local
  needs in the US
• Our institutions are participating in OSG in the
  US, and some are members of PPDG.

Some Issues

• ALICE software will have to blend with many GRID
  infrastructures.
• ALICE will use resources that will include many
  different platforms. (e.g. AliEn, PROOF and
  AliROOT now run on a variety of platforms such as
  IA32, IA64, and G5s).
• The detailed OS versions cannot be mandated on
  all resources that will need to be used.
• ALICE File Catalogs, Task Queues and Production
  Manager will interface directly to the UI/RBs
  Local Services.
• ALICE is evolving towards a Cloud model of
  distributed computing and away from a rigid
  MONARC model T-1s are distinguished
  from T-2s by local MS capability and not tasks

11
Meeting Next Week _at_ LBL

• There will be a meeting at LBL next Friday, June
  10, to discuss ALICE and OSG specifically

12
A Joint Grid Project Between Physics Departments
at Universities in Texas

• Initiated by the High Energy (Particle) Physics
  Groups
• To Harness Unused Local Computing Resources

13
In Support of HiPCAT

• High Performance Computing Across Texas
• (HiPCAT) is a consortium of Texas institutions
  that use advanced computational technologies to
  enhance research, development, and educational
  activities. These advanced computational
  technologies include traditional high performance
  computing (HPC) systems and clusters, in addition
  to complementary advanced computing technologies
  including massive data storage systems and
  scientific visualization resources. The advent of
  computational grids -- based on high speed
  networks connecting computing resources and grid
  'middleware' running on these resources to
  integrate them into 'grids' -- has enabled the
  coordinated, concurrent usage of multiple
  resources/systems and stimulated new methods of
  computing and collaboration. HiPCAT institutions
  support the development, deployment, and
  utilization of all of these advanced computing
  technologies to enable Texas researchers to
  address the most challenging computational
  problems.

14
And TIGRE

• The Texas Internet Grid for Research and
  Education (TIGRE) project goal is to build a
  computational grid that integrates computing
  systems, storage systems and databases,
  visualization laboratories and displays, and even
  instruments and sensors across Texas. TIGRE will
  enhance the computational capabilities for Texas
  researchers in academia, government, and industry
  by integrating massive computing power. Areas of
  research which will benefit in particular
  biomedicine, energy and the environment,
  aerospace, materials science, agriculture, and
  information technology.

15
Setting Up THEGrid

• THEGrid has set up a Grid infrastructure using
  existing hardware in Physics Departments on
  campuses in Texas
• Initially, a Grid3-like approach was taken using
  VDT (Going to OSG Soon)
• Local unused resources were harnessed using
  Condor

16
Using THEGrid

• Individual Students and Faculty at each
  participating campus can submit batch jobs!
• Jobs are submitted through a local portal on each
  campus
• The middleware distributes the submitted jobs to
  one of the available locations throughout
  THEGrid
• The output from each job is returned to the user
