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

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:

<?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:

<?xml version="1.0" encoding="UTF-8"?>

Created a sliver with the GUSH handle-geni.py script:
