Public Comments Sought: ISV Remote Computing Usage Primer
by Steven Newhouse 28 Aug '08

28 Aug '08

All, The Independent Software Vendor Remote Computing Usage Primer (http://www.ogf.org/Public_Comment_Docs/Documents/2008-07/ISV-V93.pdf) is currently in public comment. Abstract below: This document provides information to the Independent Software Vendor (ISV) community as to how specifications from the Open Grid Forum and other standard setting organizations (SSO) can be used to support Remote Computing scenarios. It does not define any standards or technical recommendations. Please read and make public comments by the 1st September 2008 through http://www.ogf.org/gf/docs/comment.php?id=271 Many thanks, Steven & Andrew

File staging faults
by Piotr Domagalski 26 Aug '08

26 Aug '08

Hi! Hopefully, this is the last thing that bothers me: 1. As far as I can see, there no such thing as an XML Schema for HPC File Staging Profile. Is that right? 2. Assuming that #1 is true, I'm preparing a schema for me to ease handling of the specified elements. The faults seem a bit unclear to me, though. What are their types? Are they all xsd:string? What about UnsupportedProtocolFault and DeleteOnTerminationFault from which description you can read that they could have a <File> subelement? Do they solely have this subelement or are they mixed-type so that they can contain both string and <File> subelement, e.g.: <DeleteOnTerminationFault> something bad happend <File>ftp://foo.com/bar.txt</File> </DeleteOnTerminationFault> Thanks for any clarifications! -- Piotr Domagalski

ActivityStatusType inconsistency
by Piotr Domagalski 25 Aug '08

Hi all! In the examples in latest HPC File Staging Profile (https://forge.gridforum.org/sf/go/doc15024?nav=1) the state of activity is a value of bes-factory:ActivityStatus/bes-factory:State whereas according to the latest BES XML Schema (https://forge.gridforum.org/sf/go/doc15062?nav=1) it is put into an attribute of the bes-factory:State element. -- Piotr Domagalski

Re: [ogsa-hpcp-wg] [SAGA-RG] Hosted applications

There is also a bit of overlap here with the Application Template done in the HPC Profile WG. http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.ogsa-hpcp… The main goal of this spec is to reduce the amount of info the user has to specify in a JSDL document and let the system admin provide (server side) the details needed to run a particular admin on a local cluster.

greeting from Leitao Guo
by Guo Leitao 20 Aug '08

20 Aug '08

hi everyone, This is Leitao Guo from China Mobile Research Institute. I'm engaged in the research of high performance computing and distributed database. I subscribed the mailinglist of OGSA-HPCP-WG, but didn't receive any email. I don't know whether there is something wrong with my subscription, or this group is not active any more. Can anyone tell me the work status of this group? Many thanks! Leitao 2008.8.20
