futhark multicore [options…] <program.fut>
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
.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
Accepts the same options as futhark-c.
The C compiler used to compile the program. Defaults to
Space-separated list of options passed to the C compiler. Defaults to
-O3 -std=c99 -pthreadif unset.
Generated executables accept the same options as those generated by futhark-c. The following additional options are accepted.
- -P, --profile
Collect and report various bits of profiling information.
Use this many physical threads.
Currently works only on Unix-like systems because of a dependency on pthreads. Adding support for Windows would likely not be difficult.
