5 ALICE/Pinsky OSG Applications SLAC 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 DOE’s 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/Pinsky OSG Applications SLAC 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 ALICE-USA intends to supply a similar fraction from existing commitments.

7 ALICE/Pinsky OSG Applications SLAC ALICE-USA Grid Middleware  We will support ALICE’s 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.

10 ALICE/Pinsky OSG Applications SLAC 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 G5’s).  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-1’s are distinguished from T-2’s by local MS capability and not tasks…

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 toenable Texas researchers to address the most challenging computational problems.

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.
