graphs not found after compiling and running the project #2

Closed avionicscode closed 4 years ago

avionicscode commented 4 years ago

thank you for sharing this great project i am using Ubuntu 18.04 i followed your description in the Readme file

when i run make all DIMS=8

the project compiled and the .o files created in bin directory then after i run ./bin/SkyBench -f workloads/nba-U-8-17264.csv and ./runExp.sh -p -i workloads/ -t 8 -c 1000000 -d "2 4 6 8 10 12 14 16 18 20 22 24" -s "bskytree hybrid" i get .csv files in the result folders

i want to know how do you get the graphs in figure 5 fig 6 ... and figure 13 in your published paper ICDE 2015 (Scalable Parallelization of Skyline Computation for Multicore Processors).

please is this the code not enough to generate those graphs

if i compile the project in a 4 core laptop are there changes i can make to your code to get the results in your published paper ?

i changed threads="4"

but it not worked

@avionicscode , thanks for the questions and sorry for the slow reply!

We did not include in this repository the code used to generate the plots. This was done in LaTeX, using the pgfplots package. pgfplots reads the .csv files directly. You should be able to use any plotting software (e.g., gnuplot or MS Excel) to recreate similar plots.

For a 4-core processor with hyper-threading enabled, it probably does not make sense to scale the experiments beyond 8 threads. You can control the number of threads in the ./runExp.sh script with the -t [num-threads] flag. Is this what you have already tried?
