Among those, we believe the following top 10 posts stood out in our view and were viewed by many readers. We observe a trend of software efforts to catch up with utilizing multicore processors.

Multicore Research Papers - 2009: Parallel computing, computer architecture conferences publish numerous multicore related papers. We could collect a small set of these papers and posted on this page.

Parallel Programming Tutorial Series: There are a lot of online tutorials on parallel computing. We categorized some of these tutorials into Basic Parallel computing, MapReduce, Cell Processor Programming, OpenMP, pthreads, Intel TBB, MPI, CUDA, and OpenCL. Many readers found these very useful, especially CUDA and OpenCL ones in the wake of heterogeneous computing.
