tasks and jobs...
by Andre Merzky 08 Feb '06

08 Feb '06

Hiho, I can't remember exactly where the sugegstion came from, but here it is anyway. Wouldn't it be useful to have jobs implementing the task interface? Well, the advatages would be: - you can put jobs into tak containers, and wait() for them to change state/finish - if we have notification on tasks (see earlier mail from November or so), we have now notification on jobs as well, w/o the need to introduce a new mechanism - it seems simple to map the job states to task states: Done -> DoneOK Failed -> DoneFail all others -> Running (as a side note, we should consider have the same names for Done and Failed...) The only difference I see in terms of semantic is that tasks can be Pending - i.e. not yet started. Jobs can't, as soon as you create them, they are at least Queued. However, that is a topic I wated to open anyway: One of our earliest use cases is bulk job submission (from Hrabri/DRMAA). The current API does not allow to implement that use case efficiently - the only possibility is: for ( int i = 0; i < 1.000.000; i++ ) { my_jobs[i] = job_server.submit_job (job_description[i]); } Having jobs more task like would help: for ( int i = 0; i < 1.000.000; i++ ) { task_container.add_task (job_server.create_job (job_description[i])); } task_container.run (); The semantics would be now: job = job_server.create_job (job_description); // job is pending now job.run (); // job is queued now, or whatever - see previous mail. That argumentation is very similar to the one we hade about task creation: there we have: task t1 = file.read <async> (...); // t1 is running task t2 = file.read <task> (...); // t2 is pending t2.run (); // t2 is running same for jobs then: job j1 = job_server.submit_job <async> (...); // t1 is running job j2 = job_server.create_job <task> (...); // t2 is pending j2.run (); // j2 is running Feedback as always would be very welcome. An issue in that respect is in the issue list (since a couple of weeks actually). Best regards, Andre. -- "So much time, so little to do..." -- Garfield

Miscellaneous Review issue list I have reserved eight lines for this call, as we had six participating last week, and I know at least one more person will join today. If you are not one of those seven and plan to join, it would be good to know so I can reserve more lines; as far as I can tell reservation isn't required, but if the system is busy with lots of other conferences it is possible that there might not be a free line apart from the reserved ones. Cheers, Tom

Comments to use case document
by Andre Merzky 06 Feb '06

06 Feb '06

I promised at the last phone call to send the URL to the use case comments: http://forge.gridforum.org/forum/forum.php?forum_id=562 BTW, the comments to all docs can be found on the GGF pages under: main -> documents -> public comments -> archived comments So, if anybody feels included to address the comments in the UC document, you are more then welcome! The main points are I think: - the readers did not understan what SAGA wants to do (Ian) - the reader did not realize that the requirement document is a separate document, and hence requirements are NOT in the UC document. Appearently, these points are not clear in the document, that needs to be taken care of. Please note that the comments from Rion, Zhou and Chirag are actually for the wrong document (the strawman API), and got into the forum due to miscommunating of URLs...

CVS emails
by Tom Goodale 06 Feb '06

06 Feb '06

Hi, Andre, Shantenu and I have been discussing the cvs mails. Currently they go to the saga-cvs mailing list, but this only has eleven people on it, although I assume they are the most interested. Andre is concerned that few people see the mails and realise the work which is going on and has suggested that the mails go to the main mailing list. My feeling is that a lot of people would just consider them spam, or otherwise an annoyance, and may be less likely to read saga mails at all - I know this is the effect it has on me on other lists where discussion and cvs mails get mixed. As a compromise, I suggested that the saga-rg list be subscribed in digest mode to the cvs mailing list. Anyway, I thought that it would be best to just ask the whole list what they want done: 1) Current status - saga-cvs and saga-rg mailing lists are independent 2) Digest of saga-cvs mails sent to saga-rg 3) All saga-cvs mails sent to saga-rg Cheers, Tom

Group Charters...
by Andre Merzky 05 Feb '06

05 Feb '06

Hi, notwithstanding the fact that the group did not yet finalize its decision on WG/RG formationsplitflip, we don't have much time until GGF16 to settle the formal issues of that process. As a split is amongst our options, we need to discuss the appropriate charter updates for the resulting groups (Thanks to the ADs for the reminder). Attached are drafts for a WG and RG charter (they are in CVS). Please note that the groups in question are named SAGA RG and SAGA WG -- that is not normative ;-) as we did not decide on the names yet, either. Please also note that the list of deliverables etc. is sketchy at best - I am not sure what document should get finalized in which group. However, feedback would be most welcome to the scope and goals section of the RG charter. As we settle on that part, the remaining pieces should fall into place. The drafts are solely my opinion right now, and probably somewhat off target - so don't blame the other chairs, please :-) I assume that we don't need to answer the (in)famous 'Seven Questions' again, as I think there is no doubt that the groups have a right to exist - they are called for by the GFSG, right? Cheers, Andre. -- "So much time, so little to do..." -- Garfield

BOUNCE saga-rg@ggf.org: Admin request of type /^\s*help\s*$/i at line 8 (fwd)
by Shantenu Jha 04 Feb '06

04 Feb '06

From: Andre Merzky <andre(a)merzky.net> To: Simple API for Grid Applications WG <saga-rg(a)ggf.org> Subject: CVS notifications to mailing list? Hi Guys, we consider to forward a weekly digest of CVS change notifications to the mailing list, for several reasons: - we are doing a bad job in keeping the list up to date with the status of document work - the CVS logs might help - we hope to get people interested if they see there really happens something... :-) - it would motivate us to write better CVS log messages (well, would motivate me at least, as I am the lazy one...) OTOH it means automated mails reach the list. Any opinions? Well, I am obviously for it :-) Cheers, Andre. -- +-----------------------------------------------------------------+ | Andre Merzky | phon: +31 - 20 - 598 - 7759 | | Vrije Universiteit Amsterdam (VU) | fax : +31 - 20 - 598 - 7653 | | Dept. of Computer Science | mail: merzky(a)cs.vu.nl | | De Boelelaan 1083a | www: http://www.merzky.net | | 1081 HV Amsterdam, Netherlands | | +-----------------------------------------------------------------+
