 THRUST: a variety of thrust primitives are used throughout GGMS, so it is
 necessary to have a copy downloaded. For convenience a copy has been
 included.

The folder contains the following files:

Distributed version of selecting multiple order statistics:
distributedSMOS.cpp
distributedSMOS_Kernel.cu

Iterative version of selecting multiple order statistics:
iterativeSMOS.cu

Sorting version of selecting multiple order statistics:
bucketMultiSelect.cu

Algorithms for generating distributions and printing information:
generateProblems.cu
printFunctions.cu

Compare Iterative and Sorting version of SMOS:
compareIterativeSMOS.cu
iterativeSMOSTimingFunctions.cu

Compare Distributed and Iterative version of SMOS:
compareDistributedSMOS.cpp
distributedSMOSTimingFunctions.cu
distributedSMOSTimingFunctions_Kernel.cu

To begin with, make sure you can remote connect to following computers using 
ssh without entering password. You can try typing the command
ssh bollee
ssh bellman
ssh householder
ssh mccarthy
to see if you can connect to them successfully or not.


Then cd to folder DistributedSMOS


To compare Iterative and Sorting version of SMOS, firstly using one of the four
ssh command above to connect to those computers remotely. Then, using the following
command one by one to compile the files:
PATH=$PATH:/usr/local/cuda/bin
nvcc -I./lib/ -I. -arch=sm_60 -lcurand -lm -c iterativeSMOS.cu -o iterativeSMOS.o
