📦 Running The Project

stack install

stack build

stack exec ParVarys-exe

➕ Adding Packages

• To add a package I think you have to first add it to extra-deps section of the stack.yaml
• Then you have to add it to the dependencies section of the package.yaml
  • You may also want to add it to the executable dependencies section

📝 Installing threadscope

Command To Run

stack install --flag gtk:have-quartz-gtk threadscope

Testing it works

threadscope --test ch8

This should launch a window

For more information see this: https://wiki.haskell.org/ThreadScope

Trying a more involved example

This command runs the ParVarys executable using 4 cores, and generates the event log ParVarys-exe.eventlog:

stack exec ParVarys-exe -- +RTS -N4 -lf

To visualize the event log using threadscope

threadscope ParVarys-exe.eventlog &
