Why ALICE Tier-2 in Tsukuba ?
• Contributions to ALICE by Tsukuba (-2015):– EMCal/ DCal detector construction, installation, operation– Data analysis (jets, bulk properties)• After LS2, ALICE data volume in Run-3 will be x100, needed computing
resources worldwide.
• ALICE offline management asked U. Tsukuba to contribute to computing(ALICE analysis and T1/2 workshop in Tsukuba, March. 2014)• Recent talks on the future ALICE computings:•

AFAD2015: The ALICE computing upgrade project and network in Asia (TC, Jan, 2015)•JPS 2015 spring symposium: Computing in LHC ALICE (TC, Mar. 2015)•WLCG 2015 at OIST: Evolution of the ALICE Computing Model in Run 3 (TC, Apr. 2015)• Goals:• For the future of ALICE, establish another Tire 2 site in Japan.
• Utilize a fast and wide bandwidth only among Tire sites (WLCG,LHCONE), without degradation of data transfer speed by firewalls.

Goal:
Another ALICE T2 in Japan
Academic backbone SINET 4/5
Status:Infrastructures (space and power) ready.
16 WN’s (X5355 x2, 4c@2.6GHz) in a rack.
Visited Hiroshima T2 to learn on May 28.
Installation of EMI 3.1 and host certification has been
finished.
Installation of basic services is almost done.
Used IP: HepNet-J (well establish connection (old) for
HEP community)
Connected to SINET-4 (via HepNet-J).
Slide by N. Nakamura (NII) @ AFAD2015
Plan:
Establish basic services in Oct. and start test operationin Nov. (ask ALICE for test job submission).
Connection to SINET-5 will start Oct.
Will use Univ. IP for head nodes towards the future
16 WNs (provided by Hiroshima U)
connection to WLCG and LHCONE.
as a proto-type of T2 in TsukubaCommunication with WLCG in Oct-Nov.

Also need to communicate with U.Tsukuba info. center

Plan: Connection to SINET-5 and LHCONE• Use University’s IPs.
• Connect to LHCONE via
VLAN.
• Path control for LHCONE by
Managed byown router (read), managed by
ALICE Tsukuba
us (ALICE Tsukuba).
• FW: managed by University.
• Need a ICSIRT.
• No such framework so far,need to communicate w/ Univ.
academic info center.

ALICE T2Tsukuba
7Summary• The setup of prototype for Tsukuba T2 site (minimum setup)is almost finished, still need to install several services (sBDII,DPM-SE, CREAM-CE) on head nodes.
• After the setup is done, we would like to ask for site tests.
• In parallel, we are working on the network on campus toestablish the lines for Grid, WLCG and LHCONE.
• Will communicate with ALICE and WLCG soon.
• A new JSPS Grant application will be submitted for ALICE
detector upgrade and a lager scale Tsukuba T2.
