Yeah, it's a 32-bit file. However, I tried the 64-bit versions from Jeff's page (SVN 942 and SVN 939). Both of them throw errors on the actual linear algebra:
Code:
lanczos error: submatrix is not invertiblemensions (0.0%, ETA 14h39m)
lanczos halted after 5 iterations (dim = 250)
linear algebra failed; retrying...
I'm going to try rebuilding a 64-bit version from the latest SVN.
Edit: And now I'm reminded why I didn't have a 64-bit version yet...errors at the literal last step of compiling about not being able to find correct calls to a couple of GMP-based functions. In the meantime, using the 1.51 version that works.
