Notes from the STEM Call on November 9, 2017
On the call: Jamie, Stefan, Matthias, Taras, Ahmad, Nereyda, Tekla, Emily, Judy
Next call: Thursday, December 14, at 9 am Pacific Time
Welcome to Ahmad Swaid, new at BfR, as a STEM contributor and future committer
1. STEM 3.0.0 Milestone 5: Release to follow solution of problem with launcher on Mac
*Pending solution: See item 3
*Hack not advisable, workaround available at
https://www.eclipse.org/forums/index.php/mv/msg/1084123/1753241/#msg_1753241
2. Updates
*Wiki updated on need to use appropriate solvers such as Runge Ketta Cash-Karp https://wiki.eclipse.org/Running_an_Automated_Experiment
*Section on pubs and presentations on website updated
*Fix created for square lattice; zip file included in the Agenda for 11/9/2017
*TO DO: Once she has confirmed setting the limit to 1000 works to get an infinite rate (protection rate) works, Emily will contribute text to wiki
3. STEM Move
*New build server is up, running ok; Stefan updated to run on Mars
*Jamie: Use very latest Eclipse & plug ins to regenerate all STEM models; first update target platform, then update using XML
Process: Update STEM [Eclipse stem UI; stem2.product; target platform (Luna) stem3.target]; download Eclipse [all latest version plug ins STEM uses; update, test]; once tested, update the Delta packs used in running STEM
*Matthias: Ahmad Swaid will take this on, has begun project work
*Ahmad: Couldn’t make build using product 5; per Jamie, can’t build STEM from product any more, TO DO: Check doc to see if update needed on this
TO DO: Jamie to promote Ahmad to an Eclipse committer; Ahmad to send Jamie a short bio for Eclipse; Matthias will help Ahmad with the Eclipse forms
TO DO: Ahmad, Jamie & Stefan: Use stem-dev, private phones calls to resolve technical issues
TO DO: Until he has committer status, Ahmad can send fix as a patch to Bugzilla and Jamie or Stefan can commit for him
4. Bugs
No new bugs reported
5. Items from Participants
*Nereyda: Will present poster on 1/7/2018 at Transportation Research Board; will create one-page handout on STEM, will send out for review once drafted
TO DO: Jamie to send Nereyda paragraph on STEM for inclusion; can possibly repurpose one-pager for galaxy display at IBM
*Tekla: Having problems with model generator, launching on Mac; per group could be an EMF bug, could be another Mac security problem; she will share log file
TO DO: BfR will help Tekla tomorrow if she will share screen; will let Jamie & Stefan know if bug is related to the new build server
*Emily: Wants to better understand stochastic solver; is looking at code; per Jamie and Stefan, code in stemcore math; depends on binomial distribution from Apache Math Commons 3.1, also standard stochastic in Java, really a short method now
TO DO: Stefan will send write up he did or Melbourne researchers
*Re random number seed: Don’t set range in the disease model; changes moved noise into the solver but kept in model for backward usability; run experiment over and over, not as an automatic experiment; try two batches to see if it works
