Meeting Notes:

Next Teleconference: September 10, 2012 .

Looking at HPC-10 and network performance is not up to spec yet - it may be a configuration and NIC slot placement. On paper this should be sufficient for VEGAS purposes. A serial testing of configurations then NIC card placement would be best to identify what has the best effect.

Other bottleneck for testing - is the purchase of Roaches & Mezzanine. There are occasional crashes on power PC bootup for the three production cards that were built. UCB will get next information on 8am PDT Wednesday morning (radio astronomy lab number) Mezzanine cards are build but there is no test fixture.

The plan for the next firmware test should wait until production Roach2. All the R1 tests that are practicle have been completed. A single Roach with an AsiaA ADCs. should be sent to GB as soon as it is ready

Mode "13" testing is being held up by network issues to be addressed today.
