[Fwd: Proposed extension]
by Michel Drescher 12 Sep '06

12 Sep '06

Folks, meanwhile I figured out (thanks Joel!) that the Argonne mailman doesn't like ZIP files. :-( I attached a renamed ZIP file - rename it to "Archive.zip" and it should work out of the box. Cheers, Michel -------- Original Message -------- Subject: Proposed extension Date: Fri, 07 Jul 2006 13:55:10 +0100 From: Michel Drescher <Michel.Drescher(a)uk.fujitsu.com> To: JSDL WG <jsdl-wg(a)gridforum.org> Folks, sorry for the delay - my fault. I sent the revised proposal to the "wrong" mail address jsdl-wg(a)ggf.org. Obviously, this mail address is a dead end. :-( Please find attached two proposed JSDL extensions. The attachment contains the schemas, and a list of examples. NOTE: The multi job extension requires two backwards compatible changes to the JSDL v1.0 schema itself: a) jsdl:JobDescription gets an "id" attribute of type xsd:ID b) jsdl:JobDefinition allows more than one jsdl:JobDescription element. I will update/create the necessary specification documents after the next round of rotten eggs. ;-) Cheers, Michel -- Michel <dot> Drescher <at> uk <dot> fujitsu <dot> com Fujitsu Laboratories of Europe +44 20 8606 4834 -- Michel <dot> Drescher <at> uk <dot> fujitsu <dot> com Fujitsu Laboratories of Europe +44 20 8606 4834

POSIXApplication Limits
by Peter G. Lane 07 Sep '06

07 Sep '06

I'm confused about many of the limits in POSIXApplication. Some seem redundant with respect to the Resources requirement elements. Other's simply don't seem clear in their spec descriptions. In general, it seems unclear whether "job" refers to the entire job or a single process. For example, MemoryLimit says "...the maximum amount of physical memory that the job should use when executing", whereas CPUTimeLimit says "...the number of CPU time seconds a job is allowed to consume before a SIGXCPU signal is sent to the job". In the first case I would interpret "job" to mean the one or more processes a job spawns in the process of achieving completion. In the second case it seems that "job" means an individual process. Is it then impossible to specify a total job CPU limit for all processes, or is that what TotalCPUTime in Resources is meant for? But then it's not so clear why MemoryLimit is not redundant with TotalPhysicalMemory. Here are some more specific questions: WallTimeLimit -- Why isn't there a hard wall time limit if this is a soft limit? DataSegmentLimit -- What is meant by a data segment? VirtualMemoryLimit -- Similar to MemoryLimit, what's the difference between this and an UpperBoundedRange value for Resources' TotalVirtualMemory? Is there some reason someone would want to request nodes with a total virtual memory capacity greater than they are limiting their job to use? Thanks! Peter

[Fwd: [ogsa-wg] JSDL support in GRAM]

Ian's email to the JSDL group bounced. -------- Original Message -------- Subject: [ogsa-wg] JSDL support in GRAM Date: Wed, 19 Jul 2006 11:44:26 -0500 From: Ian Foster <foster(a)mcs.anl.gov> To: ogsa-wg(a)ggf.org, JSDL Working Group <jsdl-wg(a)ggf.org> Hi, Some people asked me about this issue, so I thought this email me might be of interest. Peter Lane (lead GRAM developer) tells me that a first prototype of JSDL support in GRAM has been completed. For those wanting to learn more, details are at http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=4545. Feedback, or volunteers for early evaluation, would be welcome. Peter notes that he has been able to submit the following simple JSDL job using the JsdlGramJob class: <?xml version="1.0" encoding="UTF-8"?> <jsdl:JobDefinition xmlns:jsdl="http://schemas.ggf.org/jsdl/2005/11/jsdl"> <jsdl:JobDescription> <jsdl:Application> <jsdl-posix:POSIXApplication xmlns:jsdl-posix="http://schemas.ggf.org/jsdl/2005/11/jsdl-posix"> <jsdl-posix:Executable>/bin/date</jsdl-posix:Executable> </jsdl-posix:POSIXApplication> </jsdl:Application> </jsdl:JobDescription> </jsdl:JobDefinition> Regards -- Ian. -- ------------------------------------------------------------------------ Dr A.
