This took 0:46:37 in J and 0:53:28 in bc on my XP machine. However, when I
split the calculation into pieces, it was finished in less than 15 minutes.
I ran the following two scripts simultaneously, using "fork" (which took
about six minutes), then loaded the results and made the final calculation:
load&.>'partial1.ijs';'partial2.ijs'
+++
+++
6!:2 'ans0=. 1+28433*partial1*partial2'
518.91352
10{.":ans0
7772839072
#":ans0
2357207
The results above were produced by these two scripts:
NB.* large1.ijs: portion of large calculation.
ans1=. 2x^3915228
('partial1=: ','x',~,":ans1) 1!:2 <'partial1.ijs'
2!:55''
NB.* large2.ijs: portion of large calculation.
ans2=. 2x^3915229
('partial2=: ','x',~,":ans2) 1!:2 <'partial2.ijs'
2!:55''
