NetFPGA Summer Camp : Aug 4-8

• Agenda and plans are on-line as:
  • SummerCamp2008
    • Glen, Adam, Sara, Jad: Update your plan for Assignments on Tuesday, Aug 5.
    • I will review progress on your work this Friday at 9am

Equipment (John, Adam, Glen, Jad)

• On sunday, starting at 10am we need to set up equipment in Gates 104
  • John (self) and Adam met in the lab on Sunday at 11am-9pm

LCD Screens

• John (self) and Adam: We need to borrow your LCD during the tutorial.
• Glen, Jad, DavidE - We need to borrow your secondary monitor during the tutorial (Keep primary)
• The remaining five screens are due for delivery this week.

NetFPGA cards

• Allocate three NetFPGAs as prizes for attendees

NF-Test Machines

• We need all of the nf-test machines returned to the wire rack in the Flash Lab by Wednesday
• Adam will re-image and load software on machines by Friday
• We will set up the machines in Gates 104 on Sunday.

SIGCOMM Tutorial (Adam, John)

• John and Adam will drive nf-test equipement to Seattle on Thr. Aug 14.
• Guido and Brandon will return with equipment on Friday, Aug 22.
• We plan to rent a van for this trip. Details on Travel Wiki.

PTP Demo (Sara, Jad)

• Please describe the progress on testing with the NetFPGA Cluster
  • Were you able to use nfcM1..16 for the 20-node test?
  • nfcm1-3 are not up for some reason. Everything is wired up. We will run our tests today (Wed).
• We need the nf-test machines back by Wednesday
  • Adam said it's ok if we kept them till Thursday. We'll try to finish with them today(Wed).

User migration from nf-test to nfc machines (Adam)

• Migrate work from nf-test machines to nfc

LiveCD (Jad)

• Can we demonstrate OpenFlow running from the LiveCD?
  • Yes, but not tested yet
• Can multiple nf-test machines be used to run OpenFlow?
  • Yes, but not tested yet.
• Has documentation about this LiveCD been added tothe Guide?
  • Already started. But shouldn't be in the guide. LiveCD

Website update (John)

• New website goes live this Wednesday at Noon
• Draft copy on-line as: http://netfpga.org/test
• Backup will go to: http://netfpga.org/orig

Testing of first cards from new batch of NetFPGAs

• Status of Card #1
  • Shipped back to Stanford
  • Passed power voltage test
  • Passed clock test
  • JTAG Chain shows two devices but with IDs of FFFF..00
  • Issues with Spartan (Adam- Please detail)
• Status of Card #2
  • Power is good
  • Operating same way as board #1
• Discussion with JohnL/Adam/Jim on 8/5/08
  • We have asked Jim O'Dell to verify that bare-board electrical test was run
  • We suspect that FPGAs on the boards may have been over-voltaged on startup
  • Jim will ask to have FPGA devices replaced on board #2

Update on DDR2 (Jianying)

• Please update Text below:
• Corner cases
  • Refresh at the end of a read block
  • Document DRAM on Wiki Page
• Current status of DRAM
  • Block size is 2036 bytes
  • Refresh cycle shortened from 7us to 1us to exercise
  • Simulation has been run continously for a week
  • Wrapper sythesizes and meets timing but does not run in hardware
    • UCF File from self-test is being used
    • Neither success counter nor failure counters are incrementing
      • Verify that DDR clock is running?
