Re: [Chicken-users] Parallel procedures in CHICKEN

Thanks for pointing it, Dan! Do you know if it is supported by CHICKEN on Windows too? 

Cheers, 

Arthur

You could build something with the posix-shm egg, and the posix unit. If you need locks, there’s the posix-semaphore egg.

I guess you could spawn a process pool and send these processes a thunk
that calculates their part and send back the result. You could use s11n
egg for that, I believe.

I’m not sure it would be faster than the regular functions though.

 

Do you recommend any specific way to create the pool and especially to  communicate between the processes? 

 

About the speed, I'll  test and report the results.

 

Thanks!
