All, - We're still working on a tricky race condition crash in SSM, and will keep providing updates as we make progress. - We're building instrumented programs to gather data for our models on message aggregation. - We're looking at various models of message flow for analysis. Shane

Dear All, Last week, we kept working on studying other candidate, CalvinFS (FAST15), for non-POSI X clientFS and designing very lough model to apply it to ASG ClientFS as well as previous studies (YCSB, IOR, and PnetCDF). Also, this work includes writing a report. Sincerely, Jongmin -- Jongmin Gim Post-Doctoral Research Associate Dept. of Elecrical and Computer Enginerring Texas A&M University 333B Wisenbaker College Station, TX 77843-3259 Phone: 979-587-8311

weekly report (clemson)
by jingxuan 16 Mar '15

16 Mar '15

Hi, everyone, Last week, we kept working on the design of security prototype. we were writing our proposal about how to make authorization decision, store object permissions, access control granularity and design revocation mechanisms. For the hardening prototype, we are working on reducing the prototype attack surface by analyzing the inputs, removing threats and using fuzzing tools to discover weaknesses.

Dear All, In the last week, we finished implementing the front-end server side deadline guarantee solution, adaptive request retransmission algorithm, and its comparison algorithms in our distributed testbed on Amazon EC2. In this week, we will continue testing their performance. Best Regards! Guoxin Liu PHD Candidate ECE, Clemson University

All, We're working on SSM issues: - The uninitialized jump bug from last week has been isolated - We're currently focused on finding the (race condition?) crash in ssm_delay et al; we've got the ability to produce the crash and will be working on isolating and providing any necessary fixes In addition, we're working on research: - We're working on queueing-theory based models of message-passing systems, and gathering the tools to support analytics - We're generating data-gathering artifacts for real systems to compliment this
