P2s2 2012 statistics
P2S2 2012 Statistics

  • 25 paper submissions

    • Each paper received at least 4 reviews

    • PC Meeting in Mid May for paper decisions

    • 15 papers were accepted (60% acceptance rate)

  • 23 PC Members

    • Many thanks for their hard work and diligent reviews!

  • Thanks to Qichang for undertaking the publicity/web chair role!

  • Thanks to Bill and Vijay for guiding us through the process of coordinating the workshop

P2S2 Opening Remarks (09/10/2012)

P2s2 2012 journal special issue with journal of parallel computing parco
P2S2 2012 Journal Special Issue (with Journal of Parallel Computing: ParCo)

  • Special Issue on “Parallel Programming Models and Systems Software”

    • Editors: Yong Chen, PavanBalaji, and Abhinav Vishnu

  • By-invitation only special issue for P2S2 2012 accepted papers

    • All 15 accepted papers were invited

    • 12 papers were submitted

    • Reviews are in progress

  • Journal requirements on acceptance:

    • Needs to have 30% additional material (cannot be the exact same as the workshop submission)

    • New results, more analysis, etc., are OK for the additional material

  • No strict plan for the number of accepted papers

    • Initial negotiation with the journal gave us 8-10 slots, but can renegotiated depending on the number of papers that meet the journal requirements

  • We are internally planning to notify authors by Nov. 20th, 2012

    • But journal reviews are often delayed, so bear with us if we are late

  • Target date for special issue publication Mar. 20th, 2013
