Present:  Steve B, Bill G, Roland H, Atul K, Peter D, Alois Peter S, Zhichao Z, Zach E., Christopher E., Maria BH, Yosef Z, Erik S

Chair: Steve
Minutes: Bill

Steve does have a no cost extension, so the LSU Fall workshop could be put off until the next year.

Asked Ian Hinder about moving Cactus code to Github.  Is anything else on the SVN server?  RH, Some tools only exist there which could be moved.  Check if the mailing list is there.   GW analysis code only exists there at this point.  SB, We want to retire that server.

• update on potential codes to be included in next release, from minutes [RH]
  • BaikalETK (Zach, Helvi)   
    Zach says he should be sending email to Helvi.  14 days until feature freeze. 
    
  • PreSync (Steve, Roland)   
    Roland and Steve have been communicating.  Issues to be resolved and working on them.  RH, could be a struggle to get everything in.
    
• feature freeze in 14 days,   https://www.timeanddate.com/countdown/to?iso=20200507T09&p0=3704&msg=Feature+freeze&font=sanserif    
  timeline [RH]   https://docs.einsteintoolkit.org/et-docs/Release_Details#Schedule_for_ET_2020_05  
  
• Release testsuite results [RH]  http://einsteintoolkit.org/testsuite_results/index.php   
  RH no updates.  More important thing is to put on the website the fails of the testing, script needs updating and should take 1-2 hours to fix up.  Best if you can see what changed easily.  Script is in the testsuite results, and link that says all the results are stored in here.  In there a Perl script is in the toplevel directory...also a CLI so that you can try this out (some details below). 
  SB needs to run the Linux tests.
  
  • bugs of severity major or worse   https://bitbucket.org/einsteintoolkit/tickets/issues?kind=bug&priority=major&priority=blocker&priority=critical&status=new&status=open      
    #2370:Wrong MoL surprises Steve, he has used it.  RH, was always incorrect in Schedule.ccl so the order could be random.  Likely changed in the last years, maybe when MoL changed, counting variables(?).
    #2368  Summation by parts, SB is anything going to happen?  Peter will look at it today or tomorrow.
    #2336 Cactus version number in Makefile, Roland will fix soon.

unanswered question on mailing list   https://www.einsteintoolkit.org/tools/unanswered.php
Apr 9: Should put in a response on the "Instabilities with Summation..."  Peter reminds us we discussed it last week.

open tickets sorted by update time   https://bitbucket.org/einsteintoolkit/tickets/issues?status=open&status=new&sort=-updated_on

tickets ready for review   https://bitbucket.org/einsteintoolkit/tickets/issues?status=new&status=open&sort=-updated_on&q=Please%20review

All other business?

Atul K. asked if he could help with gallery testing.  Atul will work with Alois Peter S. on the BBH.  Peter says the run has been done, on two machines, and starts the post-processing and there help would be good.  They will coordinate.

Chairs and minute taker for future meetings:

1st week May, 7 May 2020, Roland chair, Bill minutes

2nd week May, 14 May 2020, Zach chair, Maria minutes

Zach tried to compile ETK on cell phone.  First issue was a dumb thing, easy to fix.  config.guess file is "12 years old" since last update.  Gnu updates more frequently, could not recognize the ARM cpu.  SB says make a ticket and a pull request.  Extension of the existing script from the GNU folks.  Steve has compiled on a Raspberry Pi...Erik recalls updating 8 years ago, the config.guess for the RPi.

From above, Roland put in the chat his running the Perl update script on the command line:

perl ./compare_results.pl ET_2019_03_v0 master results/bluewaters__{1_8,2_8}.log results/comet__{1_24,2_12}.log results/golub__1_10.log:results/golub__1_12.log results/golub__2_10.log:results/golub__2_12.log results/stampede2*.log results/osx-macports__*.log

And a colon between items indicates a filename change between the two releases, as in the two Golub entries.
