Problem 1763. Primes for Large N: 2^30, System Memory Limit
I have had some problems to get trough the test suite, one of them was that my primes where in UINT32 and that failed the 'isprime' assertion.
Maybe you could change the following line
Double implemented in test suite. Intent is to find the primes, not to get snared by errant function limitations.
Currently the MATLAB function primes is able to solve this problem. Since systems always evolve, the problem's author will probably have to be constantly updating it. Or at least, once a year.
Nice merger of primes with a customized sieving to set a new speed record on a limited memory system.
