I meant 10^10 elements. However, you are right. The elements number of the data
I want to use is 10^{7}x10^{14} and nonzero is 10^{8}. I don't have the data
yet, so I confused.
Best regards,
Joon

Actually, B is very huge(more than 10^10) and sparse(about 1% dense).
(10^{10})^2 * 1% = 10^{18} which is probably not a quantity of memory that you
have available. So either the matrix is much smaller than 10^{10} or it's much
less than 1% dense.
