AWIPS Topics - 2002

• AWIPS Evolution to Linux
• Software Release Status
• Release 5.1 and 5.2
• Localization Training
• NCF Backup
• Huntsville AWIPS

3
Motivation

• Workstation (WS) performance problems at
  individual sites during severe weather
• High resolution IFPS/GFE operations
• Data Server (DS) performance problems
• Projected increases in the volume and resolution
  of data and information the system must receive,
  process, display, and transmit
• Some hardware components are approaching End of
  Life (EOL) thresholds
• Intel platforms running Linux are cost effective

4
AWIPS Evolution Steps

• Phase I Linux migration initial capability
  (FY01-FY03)
• Step One Workstation augmentation (D2D,
  WarnGen, GFE)
• Step Two Offload GRIB processing from DS to
  Linux server
• Step Three Port SBN CP to LINUX, replace HP-RT
  SBN CPs
• Step Four Full workstation functionality ported

5
Phase I Software and Hardware Architecture Change

• Porting the AWIPS Workstation (WS) software to
  high-end Intel workstations running Linux
• Porting the SBN Communications Processor (CP) to
  Intel servers running Linux
• Developing a new High Availability (HA) Linux
  based Pre-Processor (PP) server pair which will
  relieve processing loads on current HP-UX Data
  Servers (DS) and Application Servers (AS)

6
Purpose of Phase I

• Provide a performance boost for the AWIPS
  Workstation (WS) and Data Server (DS)
• Position the AWIPS program to increase the number
  of SBN data channels
• Support ingest, decoding, storage, and display of
  new data sets
• Reduce the loss of SBN data during system upgrades

T above is the total time required to run a
series of scripted Autotests which perform
meteorological actions such as loading
various loops of model, satellite, radar, and
observational data, in multiple panes
simulating severe WX workstation ops. From
prototype at FSL with all decoders ported from DS
to Linux server. Phase I project only ports
GRIB and SAT decoders.

Progress
11
Summary

• NWS has begun the process of evolving AWIPS
• Deployed two Linux WSs to 14 forecast offices as
  a demonstration project
• Currently deploying two Linux WSs to all AWIPS
  sites
• Now porting remaining WS applications to Linux
• Prototype RFC configuration at North Central RFC
  in first half of this year with complete
  replacement of HP WS with Linux WS

12
Summary (Cont.)

• Linux-based SBN Comms Processor has been
  developed and will be deployed to all AWIPS sites
  this year
• 100BaseT LAN upgrade kit has been developed and
  will be deployed to all AWIPS sites this year
• Linux Pre-Processor is under development with
  pilot deployment planned for this year
• Preliminary performance metrics indicate Linux
  migration provides the forecaster with
  significant performance boost

13
Software Release Status AWIPS Build 5

• Build 5 is executable within the Presidents
  budget
• We are on track to complete Releases 5.1 and 5.2
  on schedule (1/31/02 and 10/31/02, respectively)
• Initial release 5.2 4/30/02
• All Build 5 core mission requirements
  identified by the independent review team will be
  met
