Revision history [back]

Hi,

In a Mac OS X, with a 2.5Ghz processor and 4Gb RAM I ran the following lines in sage:

D=DirichletGroup(20);

g=D[7].extend(1600); #order 4 character

N=Newforms(g,2,names='a')

In two hours the 4Gb were full and it started writing to swap. Is it normal that 4Gb RAM is not enough to perform the above computation? I'm new to sage (and to the forum) but since sage tells me that the space

S=ModularSymbols(g,2,sign=1).cuspidal_subspace().new_submodule()

has dim 34 I was expecting it to be within the powers of my computer.

Thanks, Nuno
