ARC6ComputingElement¶
ARC6 Computing Element Using the ARC API now
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.
- class DIRAC.Resources.Computing.ARC6ComputingElement.ARC6ComputingElement(ceUniqueID)¶
Bases:
ARCComputingElement
- __init__(ceUniqueID)¶
Standard constructor.
- available(jobIDList=None)¶
This method returns the number of available slots in the target CE. The CE instance polls for waiting and running jobs and compares to the limits in the CE parameters.
- Parameters
jobIDList (list) – list of already existing job IDs to be checked against
- getCEStatus()¶
Method to return information on running and pending jobs. We hope to satisfy both instances that use robot proxies and those which use proper configurations.
- getDescription()¶
Get CE description as a dictionary.
This is called by the JobAgent for the case of “inner” CEs.
- getJobOutput(jobID, localDir=None)¶
Get the specified job standard output and error files. If the localDir is provided, the output is returned as file in this directory. Otherwise, the output is returned as strings.
- getJobStatus(jobIDList)¶
Get the status information for the given list of jobs
- initializeParameters()¶
Initialize the CE parameters after they are collected from various sources
- isProxyValid(valid=1000)¶
Check if the stored proxy is valid
- isValid()¶
Check the sanity of the Computing Element definition
- killJob(jobIDList)¶
Kill the specified jobs
- loadBatchSystem(batchSystemName)¶
Instantiate object representing the backend batch system
- Parameters
batchSystemName (str) – name of the batch system
- sendOutput(stdid, line)¶
Callback function such that the results from the CE may be returned.
- setCPUTimeLeft(cpuTimeLeft=None)¶
Update the CPUTime parameter of the CE classAd, necessary for running in filling mode
- setParameters(ceOptions)¶
Add parameters from the given dictionary overriding the previous values
- Parameters
ceOptions (dict) – CE parameters dictionary to update already defined ones
- setProxy(proxy, valid=0)¶
Set proxy for this instance
- shutdown()¶
Optional method to shutdown the (Inner) Computing Element
- submitJob(executableFile, proxy, numberOfJobs=1)¶
Method to submit job
- writeProxyToFile(proxy)¶
CE helper function to write a CE proxy string to a file.
