    391 j)  Demo all of the perfSONAR network performance tools, tests, as was done in LAMP project
    392 
    393 k)  Extension:  pull data from one slice to another, as shown in p15 from Operator A to Operator B;  authorize using GENI credentials;  how is this done?
    394 
    395 + 4/12/12 topics suggested by Harry: [[BR]]
    396  9l)  review preliminary test plan for collecting network measurements  (Jeanne)  [[BR]]
    397 
    398 + 4/19/12 topics suggested by Harry: [[BR]]
    399  9l)  review updated test plan for collecting network measurements  (Jeanne)  [[BR]]
    400 
    401 l)  Provide regression tests of various configurations, features, etc., driven by scripts  (Jeanne)
    402 
    403 m)  Formulate tutorial for users at GEC14.  What is content of the tutorial, i.e., what are the use cases?  what is different between the test plan and the tutorial?
    404 
    405 n)  Coordinate tutorial content with GPO (Mark, Niky)  when? starting in mid-May   how?
    406 
    407 
    408 
    409 == 10)  2nd configuration to gather basic host metrics  ==
    410 
    411 a)  follows p15 Experimenter C slice 
    412 
    413 a')  for GEC14, need firm plan from 7) ASAP
    414 
    415 a!'')  Introduces push of data to common node;  what protocol?  http?  XSP?  (is this GENI Event Messaging Service?)
    416 
    417 a!''')  Backup option:  Use what capabilities are in LAMP
    418 
    419 b)  Need to organize presentation of data at a web interface;  like INSTOOLS?  Introduce DRUPLE into periscope? (plan Dec 2012)
    420 
    421 c)  Extend:  gather data from user's application (like OML client)
    422 
    423 d)  Provide regression tests of various configurations, features, etc., driven by scripts  (Jeanne)
    424 
    425 e)  Formulate tutorial for users at GEC14.  What is content of the tutorial, i.e., what are the use cases?  what is different between the test plan and the tutorial?
    426 
    427 f)  Coordinate tutorial content with GPO (Mark, Niky)  when?  how?
    428 
    429 
    430 == 11)  Strategy to support multiple configurations in one slice ==
     351i)  Provide regression tests of various configurations, features, etc., driven by scripts  (Jeanne)
     352
     353j)  Formulate tutorial for users at GEC14.  What is content of the tutorial, i.e., what are the use cases?  what is different between the test plan and the tutorial?
     354
     355k)  Coordinate tutorial content with GPO (Mark, Niky)  when?  how?

     357
     358== 9)  Steps toward GEC14 tutorials ==
    431359
    432360a)  Need plan to coordinate configurations to provide make active network measurements and to collect basic host metrics in the same slice
    433 
    434 b)  For GEC13, LAMP code and INSTOOLS code were both loaded;  portal was pointed to both GUIs
    435 
    436 c)  Need to agree on strategy for GEC14:  load both types of code?  is there any chance of a unified set of tools?
    437 
    438 d)  Long term strategy:  unified set of tools
    439 
    440 
    441 
    442 == 12)  GEMINI project documentation ==
     361 - 4/19:  For GEC13, LAMP code and INSTOOLS code were both loaded;  portal was pointed to both GUIs
     362 - 4/19:  Plan to load both types of code
     363 - 4/19:  Perhaps UK could work on unified deployment plan.  Note:  Cannot use UpdateSlice.
     364 
     365b)  Long term strategy:  unified set of tools
     366
     367c)  Start with protoGENI tutorial?  LAMP tutorial?  INSTOOLS tutorial?
     368
     369d)  Arrange user workspace (GPO, Jeanne)
     370
     371e)  Need to agree on schedule for GEC14 tools:
     372 - Design review week of 5/7?  includes arch, configuration, use cases
     373 - Development complete (freeze) on 6/15
     374 - Testing and bug fixes:  +2 weeks
     375 - Prepare and test turotrial:  +1 week
     376
     377
     378
     379== 10)  GEMINI project documentation ==
    443380
    444381a)  Code on IU github  Good:  all relevant code appears to be here, including Kentuck code
