Request Types Arguments

The following tables contain the description of all the parameters that can be used to configure a request, it adds a small explanation of the parameter and the possible values.

These are all accessible for the users to specify when creating a request. The required arguments MUST be specified by the user, otherwise a validation error will occur; the optional arguments will take the specified default value if no value is given by the user.

ReReco (Top)

Required arguments

Argument	Type	Restrictions	Description
ConfigCacheID	String	ID of a valid CouchDB document	Configuration to be used in the processing jobs

Optional arguments

Argument	Type	Restrictions	Description	Default
TransientOutputModules	Comma separated list	The modules must exist as output of the processing task and must have at least one skim that uses them as input	It indicates output modules in the task that won't be stored permanently, i.e. not merged	[]

Skim arguments

ReReco has the option of multiple skim tasks specified through the following arguments. All of them are initially optional, however if SkimName#N is defined for "#N" then SkimInput#N and Skim#NConfigCacheID become not optional. Note that these definitions use "#N" as replacement for the skim number which must be sequential from 1 to the number of desired skims.

Argument	Type	Restrictions	Description	Default

SkimMemory#N	Number	Positive	Average RSS usage expected by a cmsRun process in the Nth skim	Memory specified for the processing task
SkimSizePerEvent#N	Number	Positive	Average size contribution to the output for every event in the input for the Nth skim, since the number of events in the ouput of the skim is less than the input then this value should be equal to the size of an event in the output times the skim efficiency	Size pere event of the processing task, in KBytes
SkimSplittingAlgo#N	String	EventAwareLumiBased, EventBased, LumiBased or FileBased	Splitting algorithm for the Nth skim jobs	FileBased
