= !DiCloud Evaluation = The [wiki:DICLOUD DiCloud] project delivered an integration milestone with [wiki:GushProto GUSH] supporting access to [wiki:ORCABEN ORCA] resources. Instructions were fom the GUSH [http://gush.cs.williams.edu/trac/gush/wiki/OrcaExample Orca Example] page which walks through a scenario that uses ORCA, ProtoGENI and !PlanetLab resources. Evaluation Time Frame: October 19, 2011 = !DiCloud Findings = Initially ran into problems accessing the ORCA aggregates. = !DiCloud How-to = Defined the omni_config setting to access the aggregates: {{{ [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 [pg] type=pg ch = https://www.emulab.net:443/protogeni/xmlrpc/ch sa = https://www.emulab.net:443/protogeni/xmlrpc/sa cert = ~/.ssl/protogeni/encrypted-cleartext.pem key = ~/.ssl/protogeni/encrypted-cleartext.pem [lnevers] urn = urn:publicid:IDN+emulab.net+user+lnevers keys=~/.ssh/id_rsa.pub }}} Defined the directory.xml for each of the !PlanetLab, ProtoGENI, and ORCA resource managers: {{{ }}} Created a slice for the experiment: {{{ $ helper-scripts/handle-geni.py -n -f pg -a https://www.emulab.net/protogeni/xmlrpc/am createslice gush-orca-gir INFO:omni:Loading config file omni_config INFO:omni:Using control framework pg Created slice with Name gush-orca-gir, URN urn:publicid:IDN+emulab.net+slice+gush-orca-gir }}} Defined an ORCA rspec file named orca.rpec: {{{ }}} Created a sliver with the GUSH handle-geni.py script: {{{ $ helper-scripts/handle-geni.py -n -f pg -a https://geni.renci.org:11443/orca/xmlrpc createsliver gush-orca-gir orca.rpec INFO:omni:Loading config file omni_config INFO:omni:Using control framework pg Asked https://geni.renci.org:11443/orca/xmlrpc to reserve resources.
