7. Definition of Micron systems
ESDA is a suite of applications for analyzing and categorizing both electrical and particle defects on manufactured silicon wafers
Imaging reprocessing is the tool used to perform batch quality and functional tests on image sensors built on silicon wafers

8. Esda Statement of problem
Continually increasing product complexity requires a continuous increase of power computation
To keep the workload balanced on ESDA servers historically required increasing manual overhead
ESDA system is mainly composed as follows:
A lot of small jobs to categorize chips (hundreds of thousand per day)
Few long running jobs
Summarization jobs using result from above jobs (post-processing).

9. ESDA Condor Solution
Condor provides an opportunity to have a scalable solution avoiding the need to buy additional H/W
The summarization Jobs have been selected as best candidate
List of independent scripts collected in one job
30% of CPU load was used by Post-processing
Challenges
I/O performance tuning: number of concurrent jobs
log files spread within condor pool hosts
Learning curve: understand how to ‘condorize’ existing application

10. ESDA Condor Solution Benefits Cost saving $110k (TCO)
89.4% of the entire current ESDA TCO
Automatic load balancing among the execution hosts
Released 30% of CPU load to ESDA systems
Made the addition of new features to the post-processing phase easier

11. Imaging reprocessing Statement of Problem
Test processing fine tuning
Reprocess a high volume of wafers to improve test quality
Analyze high volume of wafers after defective material return
Assure feedback both to the engineering and to the customers based on SLA
Due to the production impact it is impossible to reprocess on production servers
Long execution time jobs

12. Imaging reprocessing Condor Solution
Applied solution
Leverage condor pool using otherwise idle office workstations
Suspend policy changed: applied only on free memory availability
Re-nice of jobs to lowest windows priority
Leverage file transfer capability of condor to pass both data and executable to the execution hosts

13. Imaging reprocessing Benefit No addition H/W needed: $165k (TCO)
103% of the entire current Image TCO
No additional software installation/setting on execution workstations
High level of parallelization thanks to jobs independency
Capability to re-process one working week in few hours without impact on production capacity
