'''Announcements'''
 
* Teams Whiteboard feature does not seem to be present. David submitted a Service Now request and will follow up on it.
 
** ''Update: This feature is not available in the "government version" of O365 at the moment.''
 
* Talks for upcoming EIC SRO workshop next month
 
** Everyone should think about what, if anything we can present
 
** ''Update: Looks like we may be too late since the agenda already is filled out. I also heard Chris say something about turning people away already. [https://www.jlab.org/indico/event/378/ https://www.jlab.org/indico/event/378/]''
 
 
'''Hall-B Testbed'''
 
* Ben fixed TCP stack on FPGA
 
* Sergey B. asked folks to wait on using it until he has had a chance to test the fix
 
 
'''Offline TriDAS for testing'''
 
* Chris suggested setting up a purely software TriDAS instance that we could work with outside of the context of Hall-B
 
** Generally thought to be a good idea and Chris will look into doing it
 
 
'''ADIOS'''
 
* Carl has continued his testing of the ADIOS I/O interface library
 
* It supports multiple engines
 
* The wide area network engine uses zmq
 
** their system allows receivers to drop packets
 
** Carl's tests failed due to having too small of packets so the processes started and quit too quickly
 
* Started looking at SST engine
 
** sockets or RDMA (if it is available)
 
* Tested on Mac at 400MB/s
 
* Tested on INDRA 100Gbs system up to 1 GB/s (factor of 10 slower than hardware)
 
* Carl noted the ADIOS user interface is pretty simple and easy to use. The ADIOS authors have also been very response so far to questions/requests
 
 
'''WMS Meeting'''
 
* David suggested canceling the WMS meeting Fridays in an attempt to reduce the number of meetings
 
* There were no objections
 
 
==== Action Items ====
 
* Carl will work on increasing ADIOS bandwidth on INDRA
 
* Vardan will work with Sergey B. to get access to the Hall-B testbed once it is available so he can start stressing the TriDAS system there
 
* Chris will set up an offline TriDAS system so he can start testing it outside of the Hall-B environment
 
* Nathan will work on slides for the Marco SRO talk next week (Thurs. 4/23)
