FutureGrid Unicore 6/Genesis II endpoints
by Andrew Grimshaw 28 Aug '10

28 Aug '10

Colleagues, FutureGrid has as two of its many goals the creation of a Grid middleware testing and interoperability testbed as well as the maintenance of standards compliant endpoints against which experiments can be executed. We at the University of Virginia are tasked with bringing up three stacks as well as maintaining standard-endpoints against which these experiments can be run. We currently have UNICORE 6 and Genesis II endpoints functioning* on X-Ray (a Cray). Over the next few weeks we expect to bring two additional resources, India and Sierra (essentially Linux clusters), on-line in a similar manner (Genesis II is already up on sierra). As called for in the FutureGrid program execution plan, once those two stacks are operational we will begin to work on g-lite (with help we may be able to accelerate that J). Other standards-compliant endpoints are welcome in the future (no pun intended), but not part of the current funding plan. I'm writing the PGI and GIN working groups to see if there is interest in using these resources (endpoints) as a part of either the GIN or PGI work, in particular in demonstrations or projects for OGF in October or SC in November. One of the key differences between these endpoints and others is that they can be expected to persist. These resources will not go away when a demo is done. They will be there as a testbed for future application and middleware development (e.g., a metascheduler that works across g-lite and Unicore 6). I want to STRESS that these resources are just coming up and ARE NOT YET robust-full time endpoints. I invite the community though to help us find ways to test and use these endpoints. Andrew *Functioning here means that there are endpoints up that we have tested with respect to executing BES activities defined by simple JSDL documents, including file staging in the case of the Genesis II endpoints. Access control in the Genesis II case is via our normal mechanism. Straight HPC-Basic Profile access and access control via username/password can also be configured as needed. Documentation on these resources, as well as a process to use them more readily is not complete.

OGF PGI - EDGI Use Cases
by Etienne URBAH 12 Aug '10

12 Aug '10

Ilya, Concerning OGF PGI Use Cases : Thank you very much for your valuable comments on following EDGI Use Cases : Enforce Security of a Production Service Grid --------------------------------------------- http://forge.gridforum.org/sf/go/doc16010?nav=1 - An 'Activity' is a 'Unit of work which is submitted to a Service via an Endpoint' (GLUE 2.0) - You are right, what needs to be frozen is NOT the physical resources processing work of the malicious User, but the ongoing activities created locally for the malicious User. Prepare Desktop Grid Version of Application ------------------------------------------- http://forge.gridforum.org/sf/go/doc16028?nav=1 - This Use Case is performed more easily if the Application already runs on the Service Grid, but this is NOT an absolute prerequisite. - Service Grids trust Users and PUSH activities, while Desktop Grids trust Applications and PULL activities. So, there is NO interoperability at all. Interoperation can be achieved only by using a Bridge specially designed for this purpose. This Bridge does NOT simply forward the activities from one Grid to another Grid, but it is a statefull server performing syntactic translations, activity buffering, activity concatenation or expansion, activity wrapping, ..., which I summarize as 'marshaling'. Detailed description of this Bridge is outside the scope of the Use Case : Only the Bridge Manager needs to have a detailed knowledge of it. The other Actors only need to know that this Bridge exists, and trust it. Marshal Activities from Service Grid to Desktop Grid ---------------------------------------------------- http://forge.gridforum.org/sf/go/doc16022?nav=1 - Same answers as for the previous Use Case. I will add all above explanations and corrections, and take into account most of your corrections about English. I am going this night on vacation for 10 days, so updating the EDGI Use Cases will take a little time. Thank you again. Best regards. ----------------------------------------------------- Etienne URBAH LAL, Univ Paris-Sud, IN2P3/CNRS Bat 200 91898 ORSAY France Tel: +33 1 64 46 84 87 Skype: etienne.urbah Mob: +33 6 22 30 53 27 mailto:urbah@lal.in2p3.fr -----------------------------------------------------

Tim, Concerning OGF PGI Use Cases : Thank you very much for your valuable comments on following EDGI Use Cases : Enforce Security of a Production Service Grid --------------------------------------------- http://forge.gridforum.org/sf/go/doc16010?nav=1 I have already taken into account all your comments. Prepare Desktop Grid Version of Application ------------------------------------------- http://forge.gridforum.org/sf/go/doc16028?nav=1 - I have already taken into account most of your comments, and I have kept the 3 others as comments. - Concerning 'encapsulation' : - Do you consider it to be a goal more than a principle ? - Why couldn't a business rule stress that encapsulation has to be enforced ? - Could you provide suggestions permitting to improve the readability and meaning of my sentences ? - Concerning the 'EGI Software Rollout process' : I was NOT aware of it. But I am very much interested at it. Could you provide me a link ? Thank you in advance for your answers.

GROMACS use case refurbished
by Oxana Smirnova 06 Aug '10

06 Aug '10

Hi all, as was decided yesterday, I ported the GROMACS use case, taking into account Etienne's comments, into the new "template", see: http://forge.ogf.org/sf/go/doc16042 Etienne would probably like to review it again, as some of his comments were about the document structure, which obviously has changed dramatically. I kept the old ODT document commented by Etienne, and even its DOC version, though the latter is really obsolete and stale. Cheers, Oxana
