Profiling and Tuning a Parallel Program

1. To view the trace of your program using threadscope, use a window on your home machine (not lxpara3)

    /u1/pg/pt114/.cabal/bin/threadscope parfib.eventlog
   

2. Now measure the execution time of the program on 1, 2, 4 and 7 cores, e.g.

   ./parfib 40 +RTS -N1 -sstderr -ls
   

3. What do you conclude from your results?
