ACC: Air Cooled Crates
Currently (03/2005) there are three ACC crates at BNL (5, 6 and 7).
ACC7 hosts the four Mother Boards currently used by US DOE QCD
collaboration Alpha Testers.
CTS: Call Tracking System
A home-grown, “Bugzilla” type, problem reporting tool. QCDOC CTS is
available at
https://qcdoc.phys.columbia.edu/cts (account required).
DB: Daughter Board
There are 32 DBs per Mother Board (0-31).
Front-End Node:
Head node that provides access to QCDOC computational resources. For the US DOE QCD
collaboration the front-end node is
qcdoc.hostb.qcdoc.bnl.gov (an IBM P655 node running AIX).
Machine Partition:
A Set of nodes grouped together to run a single job. A single Mother
Board partition has 64 nodes,
while a single Rack has 1024 (64x16) nodes.
MILC Code: MIMD Lattice Computation
The MILC Code is a body of high performance research software written in
C for doing four
dimensional SU(3) lattice gauge theory simulations on
several different (MIMD) parallel computers.
The MILC Code is publicly
available for research purposes. See
http://www.physics.utah.edu/~detar/milc/
QCDOC: Quantum Chromo Dynamics On Chip
QOS: QCDOC Operating System
SSBP: Single Slot Back Plane
None currently available at BNL.
