  11. The UH/TLC2 Connection • TLC2 (The Texas Learning and Computation Center) is currently providing ~150 CPUs for ALICE Data Challenges. Support has been recognized at LCG as being among the best. • TLC2 could offer even more resources as a match to supplement support to fund ~1.5% of ALICE total computing needs (see Soltz computing presentation)… • In addition, such hardware support would also be matched with 2.0 flexible FTE in support personnel (Middleware software development, sys-admin and maintenance) L.

  14. What Are We Asking For? • A grant from the DOE Heavy Ion Physics Office to enable us to: • …Participate in ALICE as a member of the ALICE-USA Collaboration… • …Provide funding support for 2 faculty members, 1 post-doc and increasing to 3 students… • Summer salary for faculty… • Full salary and stipend support for the post-doc and the graduate students… • Travel and incidental M & O support for the group.

  23. UH group’s Physics Interests(“Fundamental”) • Properties of the QGP • qR (Q2) • …and ultimately the Equation of State. • Relation to the Big Bang early evolution and the current Large Scale Structure of the visible Universe. (This can lead to collaborations with local cosmologists…) • This is most sensitive to the nature of the QGP/Baryon phase transition, but this also needs an accurate QGP EOS… • The “Matter” Problem: How did we get the current matter distribution? • Needs a fairly precise knowledge of the QGP EOS… ^ L.
