Class PilotComputeDescription

source code

PilotComputeDescription (PCD).

A PilotComputeDescription is a based on the attributes defined on the SAGA Job Description.

The PilotComputeDescription is used by the application to specify what kind of PilotJobs it requires.

Example:

    pilot_compute_description = {
                    "service_url": 'fork://localhost',
                    "number_of_processes": 1,                             
                    "working_directory": "/tmp/pilot-compute/",
                    'affinity_datacenter_label': "eu-de-south",              
                    'affinity_machine_label': "mymachine-1" 
                   }

Attention: The PilotComputeDescription is mapped 1:1 to the underlying SAGA-Python (Bliss) job description, which is used for launching the pilot. Depending on the resource, it is required to add additional attributes, e.g. some XSEDE/Torque resources require the specification of both number_of_process and processes_per_node:

Example:

     pilot_compute_description = {
                    "service_url": 'pbs+ssh://india.futuregrid.org',
                    "number_of_processes": 8,
                    "processes_per_node":8,                     
                    "working_directory": "/N/u/luckow",
                    'affinity_datacenter_label': "us-east-indiana",              
                    'affinity_machine_label': "india" 
                   }
