[Pgi-wg] OGF PGI - Requirements for Job Description

[Etienne URBAH]

Morris, Johannes and all,

Concerning the OGF PGI requirements for Job Description :


 From the EDGI use case 'Marshal Activities from Service Grid to Desktop 
Grid', the most important requirements, sorted by decreasing priority, are :

JD3  (100)  The Job Description document MUST reference all grid 
entities in conformance to the GLUE specification

JD11 (107)  Job Description should be only used for Job Description not 
for any kind of feedback. Job status information should not be 
communicated with a 'changed JSDL'

JD4  (101)  The Job Description document specification MUST permit the 
Client to request automatic data stage-in and stage-out

JD22 (116)  Clearly separate file and directory in the data-stagings. 
e.g. within the job description the element should be clearly labeled as 
file or directory, e.g. different aspect of handling directory or a file


The other requirements labeled 'yes' are welcome, EXCEPT the 2 following 
ones, which generate too much COMPLEXITY in the Execution Service :

JD6  (103)  The Job Description document specification MUST permit the 
Client to request that at specified Activity states, the Execution 
service sets the Activity on 'Hold'   [NO]

JD8  (105)  Job Description supports, 1) service-directed data-staging 
(i.e. specify data-stagings),2) client-initiated data-staging (i.e. 
specifiy data-staging but service will do nothing only control whether 
files existing), 3) manual data-staging (i.e. no specification of 
data-staging elements)   [NO]


Best regards.
