Lessons Learned - Run Optimization xLPR User Group Meeting August 18, 2021 1
xLPR Use at Structural Integrity Associates (SI)
- Two xLPR projects at SI thus far:
- Dissimilar Metal (DM) Butt Weld Inspection Optimization (Code Case N-770)
- 24 cases, 100k realizations each case
- Linking traditional leak-before-break (LBB) with probabilistic methods
- ~16 cases, 800k realizations each case
- 400k per run
- Efficiency is key to meeting deadlines and maintaining budget!

Run Optimization (Brief Recap)
- Primary goals:
- Reduce run time (more runs in a given timeframe)
- Reduce file size (more realizations per run)
- Reduce overhead in making xLPR runs (reduce time between making runs)
for videos/presentations 3
Output Settings (1/2)
- Only allow certain outputs to be saved
- Reduce frequency of saved outputs 4
Output Settings (2/2) 5
Distributed Processing
- Allows realizations to be run in parallel across different slave processes
- GoldSim Pro allows 4 slaves, Distributed Processing has no limit (but should only use # of cores - 1)
- Nearly linear improvement in runtimes (twice the slaves means half the run time)
- GSP Slaves can be opened one at a time in the Run utility 6
Desktop Shortcuts and Batch Files (1/3)
- Slaves can also be run as a desktop shortcut 7
Desktop Shortcuts and Batch Files (2/3)
- Target: C:\Program Files (x86)\GTG\GoldSim 11.1\GoldSim.exe -s
- Start in: C:\Program Files (x86)\GTG\GoldSim 11.1 8
Desktop Shortcuts and Batch Files (3/3)
- A batch file can be made to open multiple slave processes instantaneously
- Replace n with number of slaves to open
- Suggest closing and reopening all slaves between larger runs 9
Using Distributed Processing Properly
- Must disable run in separate process
- Class View > External > Double Click each DLL
- Allows each slave to operate independently 10
