## AWIPS Topics - 2002

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

## 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

## 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

## 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)

## 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

## Phase I Linux PerformanceMetric Improvement

**Phase I Linux Performance****Metric Improvement**

- T (secs)*		247 Sec.		 174 Sec.	            127 Sec.		58 Sec.

- CPU			71.6%		  13.2%		      16.1%		58.3%

**(Current Baseline)**
**HP WS (100 Mbps)**

**Linux WS**
**(10 Mbps LAN)**

**Linux WS**
**(100 Mbps LAN)**

**(Full Phase I)****
**Linux WS,**
**PP & CP**

-  *  “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.

## AWIPS Linux Project Schedule (FY)

- Task

- Baseline

- Progress

## 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

## 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

## Software Release Status – AWIPS Build 5

- Build 5 is executable within the President’s 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

## Software Release Status
