P2S2 2012 Statistics

P2S2 Opening Remarks (09/10/2012)

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 2012 Journal Special Issue (with Journal of Parallel Computing: ParCo) Special Issue on “Parallel Programming Models and Systems

Software” Editors: Yong Chen, Pavan Balaji, 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
