NAME

       futhark-multicore - compile Futhark to multithreaded C

SYNOPSIS

       futhark multicore [options…] <program.fut>

DESCRIPTION

       futhark  multicore  translates a Futhark program to multithreaded C code, and either compiles that C code
       with a C compiler to an executable binary program, or produces a .h and .c file that can be  linked  with
       other code.  The standard Futhark optimisation pipeline is used.

       The  resulting  program  will read the arguments to the entry point (main by default) from standard input
       and print its return value on standard output.  The arguments are read and printed in Futhark syntax.

OPTIONS

       Accepts the same options as futhark-c.

ENVIRONMENT VARIABLES

       CC
          The C compiler used to compile the program.  Defaults to cc if unset.

       CFLAGS
          Space-separated list of options passed to the C compiler.  Defaults to -O3 -std=c99 -pthread if unset.

EXECUTABLE OPTIONS

       Generated executables accept the same options as those generated by futhark-c.  The following  additional
       options are accepted.

       --num-threads=INT
              Use this many physical threads.

BUGS

       Currently  works  only  on  Unix-like  systems  because  of a dependency on pthreads.  Adding support for
       Windows would likely not be difficult.
