Not covered.

Status and results of the pilot service (by VOs and sites)

Acceptance test by SA3

Gianni: tests with multiple users (4 VOs, 4roles -> 64 users each one sumitting 20 jobs) were performed by Nikolay Klopov against a machine set-up by Laurence. These tests require a special CA, that's why they were done in a closed environment. A link to the results is published in the twiki page


(10 June 2009) Testing point K of transition plan: a test with 64 distinct users (4 VOs, 4 roles, 4 attributes) has been successfully completed. 100 jobs (simple hostname) per user have been submitted and completed successfully. The test has been performed using the certification CA, with a machine where CREAM (current production version) and 4 WNs are installed. The scripts used for this test are here. The only issue found was the one related to BUG:48083. Next step will be submitting larger amount of jobs up to 5k simultaneously present in the CE.

Gianni:GRNET is going to start this week the stress test against the CREAM CEs provided by SA1. they wil start from CERN and follow with FZK. No news received from PIC for the condor-based CREAM
Antonio: It would be good if they could provide a timeline for the tests as well. Gianni will ask.

CMS

Absent.

Massimo said that some tests were performed by Stefano Lacaprara against the installation at PADOVA.

Antonio: we need reports from these tests. I will contact Stefano.

PIC

Absent

FZK

Nothing to report

Status and results of the development (by developers)

Massimo: 2666 is almost ready that fixes many bugs. Among others it features a fix for BUG:48043 (Seen at FZK) and a new parser for BLAH

Antonio: This patch will go to certification but it won't be applied for the time being to the sites in the PPS installation because we want to keep the environment stable for the tests by GRNET

Massimo: a bit of progress form the condor based submission to CREAM (for glide-ins). reports coming from US-CMS mention several issues found with proxy delegation. A debug session is being scheduled (tentatively for next week)

Open Issues (by VOs, sites, deployment teams)

None

Recommendations for release and deployment

None

Decision about termination/extension of the pilot
