#STATUS

###ORRAN

  • Big push from state and vendors to setup MOC.
  • Possible announcement from Governor
  • Requesting space / connections from BU to host MOC & to interface with the government entities.
  • Priory MSI -> ioAPIC questions with Yi and Rich. Can it be optimized?

###DAN

  • Apache / MapReduce benchmark suite running on (VMs) on KD-SESA.
  • Plan to swap MR for EBBs, let this drive the Linux library (EBBlib)
  • JA wants a write-up

###JIM

  • Bring development unto par on BG fronted w/ IBM toolchain
  • Replace GCC atomics throughout EBBRT
  • Jim had questions about the underlying routes and p2p/broadcast of tree (and how BG linux implements)

###JA

  • Torus implementation considering CNS -> SPI -> CNK (IBM firemware for BG)
  • BG includes to book and abandons them afterward (not removed from address space)
  • Elasticity as a second order to scale. I.e. cripple KH to allow for easy internode-communication
  • Will need full-blown Linixcies required for real APPs. KH allows for this integration

###MARK

  • got running on BG/P, ran comparisons between PC and BG/P
  • each allocation is allocated to a single core
  • 200 image pairs distributed across 4096 cores
  • each convolution uses 1 node, each quadrant of image has core. Determined by the division of work
  • Cumulative work on PC 122h, 9.5 minutes
  • Coming next, IO optimized version. No collective or deduplication efforts on BG, time is dominated by BG's IO path.
  • Huge datapoint hour to a minute. Scaling (law?) from quadratic to linear.
