CCS and ORNL have their own set of terminology; below are some
of the acronyms we use.
| ACTS |
The Advanced Computational Testing and Simulation
project is building a set of software tools for high
performance computing. This set of tools is known as the
ACTS Toolkit. |
| ASCR |
Advanced Scientific Computing Research (aka OASCR). One of the five
DOE Offices of Science. See the
ASCR web pages
|
| BER |
Biological and Environmental Research (aka OBER). One of the five
DOE Offices of Science. See the BER web
pages |
| BES |
Basic Energy Sciences. One of the five
DOE Offices of Science. See the
BES web
pages |
| CCS |
Center for Computational Sciences.
A national center which supports
scientific computing for the the U.S. Department of
Energy's Office of Science (formerly Office of
Energy Research). CCS is operated out of the Computer Science
and Mathematics Division of Oak Ridge National Laboratory.
See www.csm.ornl.gov
for all CSM activities; see
www.ccs.ornl.gov for pages targetted for
users of the
High Performance Computing Facility. |
| CSM |
Computer Science and Mathematics Division of Oak
Ridge National Laboratory. Where CCS is housed. See
www.csm.ornl.gov. |
| DCE |
Distributed Computing Environment used on CCS systems
for user authentication.
|
| DFS |
Distributed File System used with DCE on CCS systems.
All user home directories are kept in DFS. |
| DOE |
U.S. Department of Energy. The friendly folks in Washington
from whence cometh our funds. Office
of Science home page. |
| EES |
Evaluation of Early Systems. In-depth performance testing of
new or beta systems from high performance computing vendors.
project description
and results. |
| FES |
Fusion Energy Sciences. One of the five
DOE Offices of Science. See the
FES web pages |
| GPFS |
General Parallel File System is a large temporary-storage
area with shared access from all SP nodes.
|
| HENP |
High Energy and Nuclear Physics. One of the five
DOE Offices of Science. See the
HENP web
pages |
| HSI |
HPSS Interface Utility, an interface to CCS's archival
storage system. See the HSI manual.
|
| HPC |
High Performance Computing. Generally denotes computing
that approaches and/or passes the TeraFLOPS performance range.
|
| HPSS |
High Performance Storage System. HPSS is CCS's
archival storage system.
See HPSS web page,
HPSS manual.
|
| LDRD |
Laboratory Directed Research and Development (aka "seed money").
Funds provided by ORNL to get projects to a "proof of principle" stage.
|
| MPI |
Message Passing Interface.
|
| MPP |
Massively Parallel Processor. Generally denotes a
distributed memory computer with more than a "few" independent
processors or nodes. At CCS, the
Compaq Alphaserver SC and the IBM SP are
MPP machines.
|
| ORNL |
Oak Ridge National Laboratory where CCS is located.
ORNL is located in Oak Ridge TN. |
| PI |
Each CCS approved project has
a single Principal Investigator,
or PI for short. The PI is the scientific
head of the project supported by an allocation of
CCS resources. Although the PI may delegate
some responsibilities to account managers,
he or she is ultimately
responsible the accounts and usage that take
place under the project allocation. |
| RMS |
Resource Management System, a set of commands for running parallel programs and monitoring their
execution on Compaq AlphaServer SC. |
| SP |
The IBM SP computer (aka Eagle).
Sometimes we just call it
the SP for short.
|
| X10 |
The ORNL reservation, (specifically the part on Bethel
Valley Road).
Many of the facilities in Oak Ridge TN were
originally constructed during the Manhattan Project; back then everything
had code names. X10 was the designation for the
ORNL reservation on Bethel Valley Road.
