DiCloud Evaluation

The DiCloud project delivered an integration milestone with GUSH supporting access to ORCA resources. Instructions were fom the GUSH ​Orca Example page which walks through a scenario that uses ORCA, ProtoGENI and PlanetLab resources.

Evaluation Time Frame: October 19, 2011

DiCloud Findings

Ran into 2 problems accessing the ORCA aggregate, in particular one problem was in the RSPEC to NDL converter. This component is being modified for GEC12, RENCI folks suggested that GIR evaluation be postponed to after GEC12.

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:

<?xml version="1.0" encoding="UTF-8"?>
<gush>
    <resource_manager type="geni-plc">
      <port_map slice="bbn_gusheval" port="61414"/>
    </resource_manager>
  <resource_manager type="geni-orca">
     <port_map slice="gush-orca-ln" port="11400"/>
    </resource_manager>
  <resource_manager type="geni-pg">
     <port_map slice="lnevers3" port="61600"/>
    </resource_manager>
</gush>

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:
