Activity Reports 2016 - Paul Nilsson

December

PanDA Pilot

  • Development of pilot versions 67.2-67.3, presented at ADC Weekly, Dec 6.
  • Development of pilot version 67.4 containing urgent patches so not presented at an ADC Weekly.
  • Development of pilot version 67.5 - pre-release version to be used at Nordugrid only.
  • In progress: major event service pilot updates to support pre-fetching (67.X). Discussing implementation details with Vakhtang Tsulaia.

Pilot 2.0

Other Activities

  • Preparing for and participating in Harvester workshop, Dec 12-13, Bern
  • Harvester meeting with T. Maeno, F. Barreiro, D. Oleynik, Dec 2

November

PanDA Pilot

  • Tested and released version 66.4 (not presented at ADC Weekly since the release was exceptionally requested as an early/immediate release wanted for AES validation tests)
  • Tested and released version 66.5 (presented in ADC Weekly)
  • Tested and released version 67.0 (presented in ADC Weekly by A. Anisenkov)
  • Tested and released version 67.1 (presented in ADC Weekly)
  • Fixed a problem with using remotely calculated adler32 checksums; sometimes they are not of fixed length (they should begin with 0:s if shorter than 8 chars, but they don't). Not a pilot bug but resolved there
  • Tested eventService=true job option on several releases (incl. nightlies) which simplifies the activation of AES, discovering and solving related (release not working) and unrelated (nightlies) issues
  • In progress: major event service pilot updates to support pre-fetching (67.X)
  • Participated in preparatory meeting to discuss future overflow mechanism (R. Gardner, A. Di Girolamo, I. Vukotic, M. Lassnig)

Pilot 2.0

  • In progress: Component Model and Architecture document

Other Activities

  • Spotted a problem with using the socket python module on ANALY_LRZ. Resolved by fixing the resolve.conf in a chroot environment on the nodes. In collaboration with R. Walker
  • Spotted a problem with lcg-get-checksum which sometimes calculates md5sum when asked to calculate adler32. To be resolved on site side. In collaboration with A. Dewhurst, A. De Silva
  • Reported the ADC OTP for 2016 on behalf of the Pilot developers

October

PanDA Pilot

  • Coordinated, tested and released three Pilot versions: 66.1 (presented at ADC Weekly), 66.2 (presented at ADC Weekly), 66.3 (presented at ADC Weekly by A. Anisenkov/Site mover migration)

Pilot 2.0

  • Improved and added more material and pages to the Pilot 2.0 wiki; including a new Meetings and Conferences page
  • Co-authored proceedings paper from Grid 2016 conference; "Simplified pilot module development and testing within the ATLAS PanDA Pilot 2.0 Project"
  • Answered questions and gave a brief project update in WFMS meeting (October 20). Fernando asked about the Component Model and Architecture document for Pilot 2.0. It will be made available as soon as it is in a readable state - internally the pilot developers have not settled on the implementation (there are currently two implementations, and we need to agree on that before it makes sense to write much in the Component Model document.). The original time estimate for this document is at the end of the design stage of the project, i.e. not before the end of 2016
  • Supervised Ph.D. student, D. Drizhuk, during his stay at CERN
  • Participated in two local Harvester meetings (at Prevessin)
  • Initial (brief) meeting with P. Svirin regarding ALICE Pilot integration, to be followed up with D. Oleynik

Other Activities

  • Participated in 5 job interviews for a new BNL position
  • Presented Site Mover Migration Status (on behalf of A. Anisenkov) at the ADC Technical Coordination Board
