Week 4

• I finished the performance analysis of the matrix multiplication code.
• I collected the results
• I created various plots
• I compared and analyzed the data for similarities and differences in performance
• I began working on the report
• I created the first draft
• I discussed the revision with Dr. Taufer.
• We agreed that the framework should allow for a broader discussion of my work
• I hope to have a framework for the report finished and ready by next week.
• I helped Philip with a part of his division algorithm
• We worked on replacing sprintf with our own code for converting floats to char arrays
• I began adapting my methodology of analyzing GPU performance for the sqrt algorithm
• I began work on a test suite that would allow testing various algorithms for performance and accuracy
• Ideally, I would like to have completed my analysis of the various sqrt algorithms by next week
• I attended a Ph.D. defense.
• James, our colleague, worked on distributed constraint optimization algirthms
• His algorithms outperformed many teams from top schools.
• I found the presentation to be very interesting -- the material was very well organized and presented
• I read a paper on Message Passing on Data-Parallel Architectures
• Lifan presented the paper at our group meeting
• The talk was about DCGN, an extension to MPI that allowed message passing amoung GPU's and CPU's.
• His presentation was simple to understand and helped answer my questions
• I wanted to know if the programming model allowed for a single kernel to be executed on both CPU's and GPU's
• DCGN does not allow for this, but Dr. Taufer suggested I looked at MCUDA'
