GUSH Evaluation
GENI User Shell (GUSH) provides an execution management system that allows users to describe an experiment that the GUSH tool uses to locate, and prepare resources. The GUSH software can be checked out from the GUSH SVN Repository using username guest and password is provided out of band. This GUSH evaluation started with the existing check out of the tools and updated to Software revision 159. Nebula testing required an update to revision 160.
Evaluation Time Frame: September 21, 2011 through the end of October 2011.
Gush Findings
Attempts to get sliver details for rspec 0.2 version failed, this was addressed by making changes to the gush parsing, waiting on feature check into repository.
Attempts to start the Nebula client failed with a java exception, which turned out to be missing files that were added in svn version 160.
Gush How-to
Using and existing GUSH install at revision 142 updated to the latest revision 159:
$ cd gush/trunk; svn update $ make clean (cd api && make clean) make[1]: Entering directory `/home/lnevers/gush/trunk/api' rm -f *.o libgushapi.a api-test make[1]: Leaving directory `/home/lnevers/gush/trunk/api' rm -f gush client gush-source.tar gush-bin.tar *.o \ terminal_parser.c terminal_parser.h terminal_lexer.c terminal_lexer.log $ make all <<< lots of output deleted>>
Gush configuration The configuration for each aggregate is manual and there is some naming inconsistencies which can cause problems. Following is a table which maps the directory.xml setting to the omni settings for each supported aggregate:
Aggregate Name | (directory.xml) resource_manager type | omni_config aggregate type | ( handle-geni.py) framework (-f) | ( handle-geni.py) AGGREGATE_URL (-a) |
PlanetLab | "geni-plc" | sfa | plc | http://www.planet-lab.org:12346 |
Emulab | "geni-pg" | pg | pg | https://www.emulab.net/protogeni/xmlrpc/am |
Coordinating these across configurations and commands is important to get gush working.
First evaluated PlanetLab features. Using the following configuration files:
directory.xml:
<?xml version="1.0" encoding="UTF-8"?> <gush> <resource_manager type="geni-plc"> <port_map slice="bbn_gusheval" port="61414"/> </resource_manager> </gush>
omni_config:
[omni] users = lnevers [plc] type=sfa authority=plc.bbn user=plc.bbn.lnevers cert=~/.gcf/plc.bbn.lnevers.gid key=~/.gcf/lnevers.pkey registry=http://www.planet-lab.org:12345 slicemgr=http://www.planet-lab.org:12347 [lnevers] urn = urn:publicid:IDN+emulab.net+user+lnevers keys=~/.ssh/id_rsa.pub
Started the gush tool:
$ ./gush -P 15555 gush> Gush has learned about the slice bbn_gusheval.
Second, evaluate the PG attempt here...
Attempts to start the Nebula client failed with a java exception. Waiting on Response from Jeannie Albrecht.
