• Exercise: WorkingWithMultipleProcesses-8

  Run the Fibonacci code on your machine. Do you get comparable timings? If your machine has multiple cores and/or processors, do you see improvements in the timing as we increase the application’s concurrency?

• Exercise: WorkingWithMultipleProcesses-9

  Take this scheduler code and update it to let you run a function that finds the number of times the word “cat” appears in each file in a given directory. Run one server process per file. The function File.ls! returns the names of files in a directory, and File.read! reads the contents of a file as a binary. Can you write it as a more generalized scheduler?

  Run your code on a directory with a reasonable number of files (maybe around 100) so you can experiment ...
