You call this caching, I call it leak, it can be both ways.
It is natural to compute the class numbers of QQ[sqrt(-n)] and
it shouldn't takes GBs of RAM IMHO.
Default pari is significantly faster with stack 40MB,
is there drama nfinit vs bnfinit?:
allocatemem(40*10^6);
default(timer,1);
{f(N)=
for(a=1,N,
K=bnfinit('x^2+a);
m=K.clgp.no;
);
}
? f(10^4)
cpu time = 5,028 ms, real time = 5,057 ms.
? f(10^5)
cpu time = 1min, 14,328 ms, real time = 1min, 15,146 ms.
