[infomap-nlp-devel] Heap problem

[Christian P. <pr...@gm...>]

Hello,

I am running INFOMAP on a 32bit Linux machine and have problems when I 
try to use a large matrix, e.g. beyond 40k x 2k or 80k x 1k. My 
suspicion is that the matrix allocated in initialize_matrix() in 
matrix.c exits because it runs out of address space at around 3GB.
Does anyone have a solution besides using a 64bit system?
It seems very possible to rewrite the parts of INFOMAP to compute and 
write the matrix in blocks rather than in its entirety but (a) that is a 
lot of work and (b) would SVD-Pack run into the same problem?

Any thoughts are appreciated!

Cheers,
Christian
