I am already breaking up the d interval into chunks slightly larger than sqrt(X) specifically to parallelize and also to try to keep memory requirements low. However, I am going up to X=10^11 or perhaps 10^12, so sqrt(X) is still pretty big. So I still need advice on the cache question that I as

[sage-devel] Re: cpu cache optimization

Michael It may be useful to split your computation in L2-sized chunks. I.e. if you want to sum over all quadratic forms with |d| < X, instead of doing the computation for the whole interval, split the interval in smaller pieces. But not too small, since the innermost loop would be too small/empty

I have a very naive question. I am playing around with binary quadratic forms and have a large array of values. I loop through a,b,c and, for each triple, compute some quantity that depends on a,b,c. Then, in the inner most c loop, I wish to increment value[d], where d=4ac-b^2, by that quantity.

I did some more digging around and now I see that the section in the reference manual on "solve" is actually more useful than what is returned by "solve?" (1) It is more concise. (2) It actually contains a reference to "find_root", a numerical method for solving equations Regards, Michel
