Introduction

• What is the Jaguar/JaguarPF Optimized Library Interface?

– Interface that enables the output of statistical analysis reports on library usage, so that NCCS can easily obtain the data necessary for making decisions.

Objectives

• What are the most frequently used libraries, and which ones are considered “not supported”?

• What are the least used libraries?

• Who is using PETsc? What versions are they using?

• How many users still use deprecated packages?

• Who is using deprecated builds of libraries?

• Who is using software in /sw/xt5/ when they could instead use more efficient Cray-provided software

Methodology

• Identified libraries (linklines) within the database

• Located table containing the linklines

• Queried database and produced output from linklines

• Created script reformatting the output

• Discovered connection between linked tables

• Created query producing results based on output required

Methodology

• Determined text editor (vi) and language (PHP) for code

• Learned fundamentals of vi and PHP

• Produced code generating the most and least frequently used libraries

• Piped results to HTML file• Created table to view results

formatted based on requirements

• Created web page to view output

Methodology

• Generated an exceptionlist.txt file containing linklines to be altered to fit criteria needed

• Created function changing original linkline to preferred linkline

• Created main web interface

Future Work

• Create script that will update the database at midnight and pipe data to files in order to generate information faster when queried

• Create automatic update for exceptionlist.txt file every time a linkline is established that doesn’t fit required criteria

• Complete functions for search option

• Document all work

• Finish modifying web interface main page

• Create web interfaces for other machines (e.g. Smoky, Eugene, Rizzo, Lens, Chester)

Conclusion

• Created a successful, usable web interface to access NCCS databases

• Utilized PHP, HTML, CSS, JAVA and VI editor to complete project

• Achieved 80% completion on the project and plan to be at 90% completion before internship is over
