Scheduled Systems Downtime: March 28, 2004
The NESCC systems will be unavailable on Sunday, March 28, 2004 due to
facilities work at the National Computer Center (NCC). The NESCC systems
will be unavailable from
12:01 am EST, Sunday, March 28
to
11:59 pm EST, Sunday, March 28
Any jobs that are running in the queues on the IBM SP (cypress) or the
IBM eServer (emerald) at the time of the shutdown will be aborted and
restarted from the beginning unless the keyword "restart = no" appears
in the job script. Any jobs that are running on the CRAY T3E (hickory)
will be checkpointed and restarted from the last checkpoint when service
is restored. Please plan your work accordingly.
For more information, please contact the NESCC staff.
New IBM Power 4+ Installed
The National Environmental Scientific Computing Center (NESCC) has
taken delivery of a powerful new supercomputer to improve its modeling
capability for current customers and to provide additional capacity for
new projects as part of the Center of Excellence for Computational
Environmental Science.
The new supercomputer is an IBM eServer Cluster 1600, consisting
of 16 pSeries 655 nodes, each with eight 1.5 GHz IBM POWER4+ processors
and 16 GB of memory, connected by a high performance switch. This
system contains the next generation of IBM's microprocessor and switch
technology compared to the existing IBM SP system at NESCC. The new
system, to be named "emerald" after the North Carolina state gem, will
have a combined peak capacity of 768 Gflop/s and will contain 16
terabytes (TB) of disk space using IBM TotalStorage FastT disk
technology.
Currently, the system is being installed at the National Computer Center
(NCC) in RTP. Early access to the system is expected by the end of
February, with general availability in March. If you currently have an
active account on the NESCC CRAY T3E or IBM SP, we will create an
account for you on emerald and provide you with a password as the
system becomes available. If you don't have an account on one of the
NESCC systems and would like one, please contact John B. Smith
(smith.johnb@epa.gov or 919-541-1087) or the NESCC staff for a project
application.
