Instrumentation and Measurement (I&M) Working Session for GEC12

Wednesday, November 2, 2011, 8:30am - 12noon
Room:
Session Leader: Harry Mussman, (GPO, Raytheon BBN Technologies)

Description

This session will review the GENI I&M design and prototyping projects planned for Spiral 4 (this year), including the two large Solicitation 3 I&M D&P projects and those projects continuing from Solicitation 2. Then, it will define and discuss the priority topics that must be resolved between now and GEC13.

Summary

Agenda

This is a tentative agenda, which may change.

1) Introductions

8:30am

2) GENI I&M D&P Projects for Spiral 4

8:35am
Harry Mussman

Goals:
Provide broad data gathering, analysis and archival capability that is sufficient for scientific mission, operations, and success of the infrastructure.

Remove the burden on researcher to become a system and network measurement infrastructure expert so that researcher can better focus on the science in the experiments

Follow defined I&M architecture
Approach:
Two large I&M projects (GIMI and GEMINI) approved from Sol 3, which include groups that have provided OML, INSTOOLS and LAMP/perfSONAR tools

SOWs for remaining Year 3 of Sol 2 I&M projects focused on key topics that need to be resolved

GIMI

PI: Mike Zink (UMass Amherst)
Co-PI/Key: Max Ott (NICTA); Ilia Baldine (RENCI); David Irwin (UMass Amherst); Thanasis Korakis (NYU Poly)

Goals:

Starts with OML, and provides easy-to-use tools for GENI environment

*First focus: I&M use cases for experiments, with default OML Client in nodes that gathers passive measurements like INSTOOLS
First supported aggregates: ORCA servers/VMs and ExoGENI (RENCI) racks
First utilized experiment control tools: GUSH, with additions
First utilized interfaces: GENI AM API for resources; ns3 for topology; ssh; OMF for orchestration

*Requires XML messaging service, with pub/sub, in public IP space

*Introduces portal service, with: OML Server, for collection; Results Service, for presentation; measurement orchestration service using OMF; documentation service to create and edit MDOD. Can portal be shared with GEMINI project?

*Introduces iRODS service for user workspace and archive. Can GEMINI use iRODS? Can iRODS serve as registry for MDOD?

Begin effort: support for WiMAX sites
Consider: adding OML server with perfSONAR interface, for sharing data with GEMINI tools
Later: add sensor measurement data, carried in data network

GEMINI

PI: Martin Swany (Indiana U)
Co-PI/Key: Chris Small (Indiana U); Eric Boyd (Internet2); Jim Griffioen (U Kentucky); Zongming Fei (U Kentucky)
; Hussamuddin Nasir (U Kentucky)

Goals:

Starts with INSTOOLS, and continues to provide easy-to-use tools in GENI environment
Consider: how to gather customized data from application

First focus: I&M use cases for experiments
First supported aggregates: protoGENI servers/VMs; can these be used for HP racks?
First utilized experiment control tools: FLACK, with additions
First utilized interfaces: protoGENI API for resources; ns3 for topology; ssh;

*Continues portal to presentation service; need to add documentation service to create and edit MDOD. Can portal be shared with GIMI project?

*Continues use of Kentucky and CNRI services for user workspace and archive. Consider move to iRODS?

Starts with LAMP/perfSONAR, and continues to provide for infrastructure measurement, and for sharing of data
Continue to setup within resources assigned by slice mechanism
Consider: monitoring of clusters/racks
Consider: measurements of Layer 2 and OpenFlow paths

First focus on I&M use cases for infrastructure measurement
First supported aggregates: protoGENI servers/VMs; can these be used for HP racks?
First utilized experiment control tools: FLACK, with additions
First utilized interfaces: protoGENI API for resources; ns3 for topology; ssh;

*Continues home and global Lookup Services
Create and map MDOD into metadata that is registered

*Continue to use perfSONAR clients to present data; can these be integrated into portal?

2.2) Continuing Sol 2 Projects

LAMP/perfSONAR

PI: Martin Swany (Indiana U)
Co-PI/Key: Eric Boyd (Internet2); Jason Zurawski (Internet 2); Guilherme Fernandes (U Delaware); Ezra Kissel (U Delaware); Mathew Jaffee (U Delaware)

Goals:

Demonstrate and/or help others to demonstrate “infrastructure measurement slices” in both protoGENI and ORCA environments, with the data available at the perfSONAR MP is registered with the operational Lookup Service.

*Provide operational home and global Lookup Services
*Creates and maps MDOD into metadata that is registered in Lookup Service

*Expand authorization at interface where data is shared; introduce use of GENI credentials

OnTimeMeasure

PI: Prasad Calyam (Ohio Supercomputer Center/OARnet)
Co-PI: Paul Schopis (OARnet)

Goals:

Work with the LAMP project to understand the LAMP/perfSONAR tools, and demonstrate using them to implement “infrastructure measurement slices” in today’s GENI backbone and access networks.

*Assuming LAMP/perfSONAR tools, develop a plan to evaluate the performance of today’s GENI IP backbone and access networks, using persistent or temporary “infrastructure measurement slices”, and utilizing existing perSONAR nodes in I2 and/or other networks.

*Define a procedure for evaluating the performance of GENI’s backbone and access networks when carrying L2 VLANs; start with the existing IP measurement tools including in the LAMP/perfSONAR tools, but consider tools that are specialized for evaluating the performance of L2 networks.

*Define a procedure for evaluating the performance of GENI’s backbone and access networks when using OpenFlow (e.g., “Tango GENI”); consider how to monitor the performance of OF networks, and introducing new specialized tools.

NetKarma

PI: Beth Plale (Indiana U)
Co-PI/Key: Chris Small (Indiana U); Scott Jensen (Indiana U); Mehmet Aktas (Indiana U)

Goals:

Participate in defining the schema for the “measurement data object descriptor”, and uses of “descriptors” in tracking provenance.

*Work with the GENI community to define extensions to the “descriptor” that would locate and describe objects beyond “measurement data objects” associated with an experiment, such as scripts, images, etc.

*Modify your tools to create, gather and forward “descriptors”, that could locate and describe all objects associated with an experiment; demonstrate how “descriptors” can be automatically created.

*Work with the GENI I&M community to define a modified “descriptor” that would provide a standardized GENI “resource event record”; these records could describe events such as assignments, faults or errors.

*Add modules to your tools to create, gather and forward “resource event records”, that when logged could fully describe the sequence of an experiment.
*Work towards fitting your provenance tools into the “experimenter’s portal”.

IMF

PI: Rudra Dutta (NCSU)
Co-PI/Key: George Rouskas (NCSU); Ilia Baldine (RENCI); Keren Bergman (Columbia U)

Goals:

*Prototype and demonstrate a GENI I&M “measurement orchestration service”, based on the ORBIT Management Framework (OMF) software modules provided by NICTA, including the Experiment Controller (EC) and the Resource Controller (RC).

*Prototype and demonstrate using your pub/sub capability to transport and distribute standardized GENI “resource event records”, as defined by the NetKarma project.

DOR

PI: Larry Lannom (CNRI)
Co-PI/Key: Giridhar Manepalli (CNRI); Jim French (CNRI); Christophe Blanchi (CNRI)

Goals:

Continue to deploy a prototype Measurement Data Archive (MDA) service.

*Enforce metadata schema on archived objects, and enable access control rights as defined by the MDA specification.

*Evangelize and demonstrate how the MDA/DOR service can be used to archive published data.
