It's time to say good bye
by Michel Drescher 26 Nov '08

26 Nov '08

Folks, as some of you may know already I am moving on in my career, and will leave Fujitsu in mid-December. As my new duties will most likely have me not do any Grid/Cloud Computing business anymore it is also time to step down from OGF activities. It has been a pleasure working with you, and I definitely enjoyed the time I spent on mailing lists, in meeting rooms, and conference venues all around the world. And yes, I think we achieved some good results, too. ;-) I will hang around for some more, and keep my account on Gridforge, but don't expect active contributions anymore as I will also cease subscriptions to mailing lists. You may drop me the occasional E-Mail (via Gridforge!) - and bet on the odds of a reply. :-) Cheers, Michel P.S.: Sorry for cross-posting.

[Fwd: new email address]
by Stephen McGough 20 Nov '08

20 Nov '08

Forwarded for David Meredith as he's having problems with a new email address. steve.. -------- Original Message -------- Subject: new email address Date: Thu, 20 Nov 2008 12:03:45 +0000 From: david meredith <david.meredith(a)stfc.ac.uk> To: jsdl-wg-owner(a)ogf.org Hi all, I have been chatting with Steve Pickles who posted the comments related to the problems with LoopInteger and LoopDouble on the OGF public comments site: http://www.ogf.org/gf/docs/comment.php?id=282 I think that the following modifications may? hopefully address the issues (modified schema attached, examples below). Basically: a) The loopCount attribute now defines the number of loop iterations as an integer and the cardinality of the loop can easily be retrospected by subtracting the number of LoopCountExceptions from loopCount. b) The LoopCountException, rather than defining the actual double /value/ of the exception (i.e. the value to skip), now selects the loop iteration values to skip (always integers). c) In doing this, the previous issues relating to the precision of double values when identifying exceptions and determining the loop cardinality is no longer a problem. Are we due another telephone conference soon to discuss this and the public comments ? cheers, dave     <sweep:Sweep> <sweep:Assignment> <sweep:DocumentNode> <sweep:NamespaceBinding ns="http://schemas.ggf.org/jsdl/2005/11/jsdl-posix" prefix="jsdl-posix" /> <sweep:Match>/*//jsdl-posix:POSIXApplication[1]/jsdl-posix:Argument[1]</sweep:Match> </sweep:DocumentNode> <sweepfunc:LoopInteger loopCount="10" start="2" step="1"> <sweepfunc:LoopCountException>5</sweepfunc:LoopCountException> <sweepfunc:LoopCountException>7</sweepfunc:LoopCountException> </sweepfunc:LoopInteger> </sweep:Assignment> </sweep:Sweep>     <sweep:Sweep> <sweep:Assignment> <sweep:DocumentNode> <sweep:NamespaceBinding ns="http://schemas.ggf.org/jsdl/2005/11/jsdl-posix" prefix="jsdl-posix" /> <sweep:Match>/*//jsdl-posix:POSIXApplication[1]/jsdl-posix:Argument[1]</sweep:Match> </sweep:DocumentNode> <sweepfunc:LoopDouble loopCount="10" start="2.0" step="2.0"> <sweepfunc:LoopCountException>3</sweepfunc:LoopCountException> <sweepfunc:LoopCountException>4</sweepfunc:LoopCountException> <sweepfunc:LoopCountException>10</sweepfunc:LoopCountException> </sweepfunc:LoopDouble> </sweep:Assignment> </sweep:Sweep> -- David Meredith e-Science / National Grid Service Science and Technology Facilities Council Daresbury Laboratory Warrington Cheshire WA4 4AD Tel: +44 1925 603762 email: david.meredith(a)stfc.ac.uk -- ------------------------------------------------------------------------ Dr A.

Activity instance schema document
by Philipp Wieder 04 Nov '08

04 Nov '08

Dear All, please find an early draft for discussion at GridForge [1]. Looking at the minutes I saw that there are a number of issues to be dicussed at the telecon. Those issues are listed in Appendix B. I hope we can finalise those in the next telecon to advance the schema specification. Best regards, Philipp. [1] http://forge.gridforum.org/sf/docman/do/viewDocument/projects.jsdl-wg/docma…

JSDL Issues
by Mark Morgan 14 Oct '08

14 Oct '08

In the course of implementing some additional JSDL 1.0 features (or extensions), a couple of issues have reared their ugly heads that I wanted to bring to the group's attention. The first has to do with data staging, working directory, file systems, and everything else having to do with paths. It turns out that there are some exceptionally popular applications out there that are very poorly written. This is probably a surprise to no one, but unfortunately, its a fact of life that in the grid computing business, we have to support many of these applications despite their egregiousness. In particular, I refer to applications which cannot handle input files or paths which contain spaces. Recently, while trying to run a large batch of BLAST jobs using our new implementation of the SCRATCH file system, we discovered that BLAST is unable to deal with paths to the search database which contain spaces. As we thought about what to do about this, we realized that, sad as it may seem, it may be necessary to add to JSDL the ability to say that an Application (or certain inputs) must have paths without any spaces included. Would this be a Resource requirement? I'm not sure exactly how to classify it, but it seems like some JSDL annotation is necessary. The second problem has to do with the SPMD extensions. I feel very strongly that the enumerated type for which kind of SPMD application you are is insufficient. If you look at UVa as an example compute environment, we have at least 3 versions of MPICH running on our cluster at any given time (one each for the gcc, pgi, and intel compilers). Each one requires different libraries to be located in the search path and each one is started (sadly) with a different mpiexec. I think that a rework of the SPMD extensions to allow for some kind of greater specificity in the SPMD type is called for. Sincerely, Mark Morgan
