'''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

==== 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)
