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/
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)
