Deploying DIET and JuxMem:GoDIET + JDF Mathieu Jan PARIS Research Group IRISA INRIA & ENS Cachan / Brittany Extension Rennes Lyon, July 2004
Conducting JXTA-based experiments:the JXTA Distributed Framework (JDF) • A framework for automated testing of JXTA-based systems from a single node (control node) • Original work from Sun Microsystems • http://jdf.jxta.org/ • JDF: several shell scripts • Deployment • Jar files and script used on each node • Configuration of JXTA peers • Launch peers • Collect logs and results files of each node • Analyze results on the control node • Cleanup deployed and generated files • Kill remaining processes • Update resource
How to define a test using JDF? • An XML description file of the JXTA-based network • Type of peers (rendezvous, edge peers) • How peers are interconnected, etc • A set of Java classes describing the behavior of each peer • Extend the JDF’s framework (start, stop JXTA, etc) • A Java class for analyzing collected results • A file containing the list of nodes and the path of the JVM on each node

Deploying a JuxMem network (2/2) <profile name=“clusterManagerA" instances="1"> … </profile> <profile name=“clusterManagerB" instances="1"> … </profile> <profile name=“clusterManagerC" instances="1"> … </profile> <profile name="providerA" instances=“42“ > <peer base-name="providerA" instances=“4“ /> <rdv cluster=“clusterManagerA"/> … </profile> <profile name="providerB" instances=“42“ > <peer base-name="providerC" instances=“5“ /> <rdv cluster=“clusterManagerB"/> … </profile> <profile name="providerC" instances=“35“ > <peer base-name="providerC" instances=“6“ /> <rdv cluster=“clusterManagerC"/> … </profile>
Usage of JDF’s scripts • runAll.sh [<flags>] <list-of-hosts> <network-descriptor> • -debug: show all script commands executed • -unsecure: use rsh instead of ssh • -cleanup: cleanup JDF directory on each host • -bundle: create bundle for distribution • -install: install distribution bundle • -update: update files on each peer • -config: configure JXTA network • -kill: kill existing JDF processes • -run: run test • -nohup: run and return without waiting for peers to exit • -analyze: analyze test results • -log: keep test results and log4j logs from peers • -save: save JXTA platformConfig files • -restore: restore JXTA platformConfig files
juxmem group Common architecture: DIET + JuxMem Cluster manager + MA/LA Provider SeD + client JuxMem Client DIET + client JuxMem
Common deployment: GoDIET + JDF • 2 differents tools with different goals • DIET = GoDIET • JuxMem = JDF • Idea for merging tools • GoDIET reads the XML configuration file • Create the test.xml and host.txt files for JDF • Call JDF to configure and run the test • In the correct order
Modified DTD of GoDIET • Idea: 2 different hierarchies • The matching is done by the server tag • <!ELEMENT deployment (diet_services, diet_hierarchy,juxmem_hierarchy?)> • <!ELEMENT juxmem_hierarchy (manager+)> • <!ELEMENT manager (client*|provider*)> • <!ATTLIST manager server CDATA #REQUIRED port CDATA #IMPLIED> • <!ELEMENT client EMPTY> • <!ATTLIST client server CDATA #REQUIRED port CDATA #IMPLIED> • <!ELEMENT provider EMPTY> • <!ATTLIST provider server CDATA #REQUIRED port CDATA #IMPLIED>
Launching DIET and JuxMem entities • DIET entities • MA • LA • SeD • JuxMem entities • Cluster managers (rdv peers) • Providers / clients (edge peers) • DIET + JuxMem • MA / LA + cluster managers • Providers • SeD + JuxMem clients
Example of a common deployment (1/2) • Physical architecture • 4 clusters: A, B, C, D • 15 nodes in each cluster • Logical architecture • 1 MA on cluster A • 4 LA, one on each cluster • 4 cluster managers, one on each cluster • 3 providers per manager • 8 SeD + client JuxMem • A DIET-JuxMem client needs to connect to • 1 MA in order to use DIET • 1 cluster manager in order to use JuxMem
Example of a common deployment: DIET hierarchy <diet_hierarchy> <master_agent> <config server="clusterA-0" remote_binary="dietAgent"/> <local_agent> <config server="clusterA-0" remote_binary="dietAgent"/> <SeD><config server="clusterA-1" remote_binary="scalar_server"/></SeD> ...... <SeD><config server="clusterA-8" remote_binary="scalar_server"/></SeD> </local_agent> <local_agent> <config server="clusterB-0" remote_binary="dietAgent"/> <SeD><config server="clusterB-1" remote_binary="scalar_server"/></SeD> ...... <SeD><config server="clusterB-8" remote_binary="scalar_server"/></SeD> </local_agent> …. </master_agent> </diet_hierarchy>
Example of a common deployment: JuxMem hierarchy <juxmem_hierarchy> <manager server="clusterA-0" /> <client server="clusterA-1, . . . ,clusterA-8" /> <provider server="clusterA-9, . . . ,clusterA-11" /> </manager> <manager server="clusterB-0" /> <client server="clusterB-1, . . . ,clusterB-8" /> <provider server="clusterB-9, . . . ,clusterB-11" /> </manager> <manager server="clusterC-0" /> <client server="clusterC-1, . . . ,clusterC-8" /> <provider server="clusterC-9, . . . ,clusterC-11" /> </manager> <manager server="clusterD-0" /> <client server="clusterD-1, . . . ,clusterD-8" /> <provider server="clusterD-9, . . . ,clusterD-11" /> </manager> </juxmem_hierarchy>
Required modifications in GoDIET • Handling new XML tags • Manager, client, provider • Writing the correct test.xml and host.txt JDF files • No need to write a files.txt • New commands in GoDIET shell • Deploy JuxMem bundle • Cleanup files, update files • Retrieve log files and results files • Modified launch command • += -config -run
Work schedule for GoDIET + JDF • Modified DTD of GoDIET • Do we agree ? • Handling new XML tags • Creating the correct test.xml and host.txt files • New GoDIET shell commands => Holly and / or Mathieu ?
Work schedule for DIET + JuxMem • Deploying JXTA-C peers using JDF • Almost done • JuxMem client using JXTA-C • Started (July) • DIET using JuxMem clients code • Using API given by JuxMem (August-September)
Conclusion • Common architecture for DIET and JuxMem • A SeD is a client JuxMem • Common deployment using GoDIET and JDF • Required step before a first DIET-JuxMem prototype • Work schedule on • GoDIET + JDF • DIET + JuxMem
