ARC6ComputingElement

ARC6 Computing Element

Temporary ARC Computing Element able to submit to gridftp and arex services via the REST and EMI-ES interfaces. Use it only if gridftp services are not supported anymore. Arc6CE should be dropped once the AREXCE will be fully operational.

Configuration Parameters

Configuration for the AREXComputingElement submission can be done via the configuration system. It inherits from the ARCComputingElement configuration parameters. Below, you can find a list of parameters specific to the ARC6 CE.

ComputingInfoEndpoint:

Endpoint used to retrieve information about the underlying computing resources. Possible values include: org.nordugrid.ldapglue2, org.ogf.glue.emies.resourceinfo, org.nordugrid.rest.
