futhark run <program.fut>


Execute the given program by evaluating the main function with arguments read from standard input, and write the results on standard output.

futhark-run is very slow, and in practice only useful for testing, teaching, and experimenting with the language. Certain special debugging functions are available in futhark-run:

trace 'a : a -> a

Semantically identity, but prints the value on standard output.

break 'a : a -> a

Semantically identity, but interrupts execution at the calling point, such that the environment can be inspected. Continue execution by entering an empty input line. Breakpoints are only respected when starting a program from the prompt, not when passing a program on the command line.



Run the given entry point instead of main.


Print help text to standard output and exit.


Print version information on standard output and exit.

-w, --no-warnings

Disable interpreter warnings.
