Good morning,
I'm trying to code a prime number generator in a specified range, using GP and C, and I need to
reduce processing times.
I'm trying to use forprime and posix multithreading, but when executing the code I'm exceeding the parisizemax. I've tried with 1-15 threads, assigning 16GB of memory only to
PARI, but I still get the same error: sometimes it only calculates the first iteration of forprime_next...
Also, is there any technical documentation for the C implementation, besides the one I'm studying (User Guide, Tutorial, Introduction to gp2c, Introduction to Parallel GP) ?
