k-means Parallel R Examples

  • BENCHMARKS - some very basic, unscientific performance measurements for these codes
  • gordon-mc.qsub - submit script to run single-node R jobs on XSEDE/SDSC Gordon
  • gordon-snow.qsub - submit script to run multi-node R jobs on XSEDE/SDSC Gordon
  • gen-data.R - script to generate the 'dataset.csv' required by all of these examples
  • kmeans-serial.R - the simplest possible serial reference code
  • kmeans-lapply.R - the serial implementation using lapply
  • kmeans-mclapply.R - the shared-memory parallel version (parallel/multicore library)
  • kmeans-ClusterApply.R - the distributed-memory parallel version (parallel/snow+Rmpi libraries)
  • kmeans-foreach.R - the serial implementation using the foreach library
  • kmeans-doMC.R - the shared-memory parallel version (foreach+doMC libraries)
  • kmeans-doSNOW.R - the distributed-memory parallel version (foreach+doSNOW+Rmpi libraries)
