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!
2
 
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)
* https://www.epri.com/xlpr/announcements/
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
