[Biggrid-vlemed-vo-managers] [EGI BROADCAST] Joint EGI-SHIWA Workshops on e-Science Workflows in Budapest
by EGI BROADCAST 25 Nov '11

25 Nov '11

--------------------------------------------------------------------------------------------------------------- EGI BROADCAST TOOL : https://operations-portal.egi.eu/broadcast --------------------------------------------------------------------------------------------------------------- Publication from : Gergely Sipos <gergely.sipos(a)egi.eu> Targets : VO managers/vlemed <vlemed-vo-managers(a)biggrid.nl> ---------------------------------------------------------------------------------------------------------------- Dear Colleague, I would like to call your attention to the next topical workshop organised by the User Community Support Team of the European Grid Infrastructure. The topic of the workshop is "e-Science Workflows". The event will be hosted by the Hungarian NGI in Budapest and will be co-located with another workshop organised by the SHIWA project on a similar topic. Find the details in the below CfC. I encourage you to participate in the workshop and to distribute the call further within your project and/or community. Best regards, Gergely Sipos Call for Contributions Joint Workshops on e-Science Workflows in Budapest http://go.egi.eu/workflowworkshops EGI and SHIWA are joining forces to run a combined workshop event that will be hosted by the Hungarian NGI in Budapest on 9-10th of February 2012. The workshops will focus on the use of workflows in e-Science and in the European Grid Infrastructure in particular, and will aim to present "the art of the possible" from the perspective of those involved in delivering the service, and try to explore "what is needed" from the perspective of users in scientific researchers in the user community. In other words, we aim to put stakeholders (developers and users of grid services) together in one room so that we can collectively determine how best to advance "Scientific workflow systems" in this demanding and dynamic field. Why a joint EGI and SHIWA event and why in Budapest? Well, the answer to the first questions is that there is a great deal of "Synergy" in our two aims and as such, the target audience is likely to be an overlapping one. The combined event means that we can all hope get even more value from participating, there being an opportunity to not only learn about some of the existing workflow systems used in EGI but also, to influence the future development of such systems for our grid infrastructure. As regards the second question, Budapest is a beautiful city with a strong and proactive scientific community that is full of innovative ideas - how could anyone refuse an invitation to visit the city, especially when being hosted by our colleagues in the Hungarian NGI? For the SHIWA Workshop (Thursday 9 Feb 2011), partners of the SHIWA project will deliver presentations explaining the following key points: - What is the purpose of the SHIWA project? - What workflow services are delivered during the project? How can these services be useful to a workflow community? - How can workflow communities use the SHIWA services (store and submit workflows, etc.)? During the following day (Friday 10 Feb 2011), EGI seeks participants who can deliver short presentations covering any or all of the following as well as anyone who is willing to contribute to the ensuing discussions/debate following the talks: - What kind of e-Science workflow management system and best practices are the most widely used and/or are emerging within your community? How many and which projects, scientific collaborations, Virtual Research Communities or National Grid Infrastructures are supporting these? - What requirements do the user and operation communities have concerning the use, operation, integration and further-development of scientific workflow services? - What kind of new services should EGI provide for scientific communities and for technology developers to support the integration of workflow systems with National Grid Infrastructures? - How could a wider and more harmonised adoption of these technologies be facilitated within EGI? What role should EGI.eu, the NGIs and projects play in this process? Join us in Budapest in February and help define the future of scientific workflow - give a presentation on behalf of a workflow user group, workflow technology or service developer/provider, National Grid Infrastructure or any other EGI stakeholder! The deadline to submit presentation proposals to the EGI part of the workshop is the 15th of December. Please read the details for submission on the website of the joint events: http://go.egi.eu/workflowworkshops. Submitted proposals will be reviewed and selections made by 22nd of December. Registration will open 6 January once the programme for the workshops has been finalised. This event represents the first of a series of such workshop sessions on scientific workflow - a follow-on workshop is expected to be conducted at the Community Forum in March 2012. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- link to this broadcast : https://operations-portal.egi.eu/broadcast/archive/id/550 -----------------------------------------------------------------------------------------------------------------------------------------------------------------------

[Biggrid-vlemed-vo-managers] [EGI BROADCAST] PROD message broker outage due to upgrade
by EGI BROADCAST 23 Nov '11

23 Nov '11

--------------------------------------------------------------------------------------------------------------- EGI BROADCAST TOOL : https://operations-portal.egi.eu/broadcast --------------------------------------------------------------------------------------------------------------- Publication from : Christos Triantafyllidis <ctria(a)grid.auth.gr> Targets : VO managers/vlemed <vlemed-vo-managers(a)biggrid.nl> ---------------------------------------------------------------------------------------------------------------- Dear all, we have planned the update of the PROD broker network software for next week on Tuesday 29/11 at 11.00 UTC time. The update procedure needs to completely stop the network (all the brokers) and restart it in the new version. While this operation normally should take a few minutes, we schedule a DT for 2 hours to be on safe side. What will be upgraded? We are upgrading from ActiveMQ 5.3 to ActiveMQ 5.5, this resolves many issues that we have faced and reported in past. Major issues that will be solved by this release: - The periodical need to clean the persistent data store (removal of messages that haven't been consumed either because no-one needs them or because their consumer is dead) of the brokers in order to be able to restart them. - Ability to use wildcard subscription instead of CAMEL (which was a single point of failure) Why now? We have tested the new version on the TEST broker network during the last month and we are happy with the results. Our plan was to have the new version of ActiveMQ software deployed before the end of the year. Deploying it within November will allow us to monitor the service closely before Christmas vacations. Who is affected? Every producer or consumer of the PROD broker network. SAM as the key user of the broker network uses the broker network for the following functions: a) Retrieval of gLite WN results from WNs to sam-nagios box This is the only operation that will be actually affected. Given that WNs will fail to either find or connect to the broker network, they will not send results back to the sam-nagios box thus no alarm should be raised. On the other hand the job that wraps the WN probes will probably timeout which may cause an alarm on CE/CREAM-CE jobSubmit probes. Normally sam-nagios boxes schedule one job submission per hour and the alarm is raised on the second WARN/CRIT result so this should also not raise any alarm. b) Submission of SAM results from sam-nagios boxes to central DBs The sam-nagios boxes will fail to either find or connect to the broker network during the DT period. All results are cached locally at a directory queue on sam-nagios boxes thus if they fail to send them, they'll try later. Results are timestamped thus this should not create any issue except of delays c) Submission of SAM results from sam-nagios boxes to operation portal(s) As with central DBs, SAM results will stay in directory queue. Given that a sam-nagios may connect to the broker network before operation portal(s) after the upgrade, this may create a time window in which messages may not be consumed. Operation portal and SAM team have already implemented an synchronization procedure which will fix such issues. d) Other applications Other applications that might unofficially use the PROD network without registering could also be affected. As we don't know their usage pattern, we cannot perform risk analysis. Thank you for your understanding, Christos Triantafyllidis EGI message broker task co-ordinator ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- link to this broadcast : https://operations-portal.egi.eu/broadcast/archive/id/547 -----------------------------------------------------------------------------------------------------------------------------------------------------------------------
