Infomap didn't run well on OSX. btw, my machine is a macbook with 2.4 GHz spec running 10.6.5.
The issue was that I kept on getting a segmentation fault when trying to use the SVD (singular value decomposition) routines to decompose the word-document matrix. Error 139 if I remember correctly.
Luckily, someone had written a post on the mailing list archives (if you list 2,000 messages, you can skip past the spam - the interface for that archive is truly appalling). The problem seems to be with 64 bit machines and memory allocation. Not being familiar with the code or too groovy with C, I'm the wrong person to sort it out. There was a patch but trying that and recompiling didn't do much either - just a different error and earlier in the analysis process.
So I've abandoned Infomap on my Mac and gone to my Asus 701 netbook! It's a 32-bit machine so shouldn't come across the same problem. Right now, it's running on a limited corpus of 1,659 documents which is a lot but not as many as I'd hoped. Perhaps when I can get my family and myself more settled, I can get a desktop machine that can handle as much as I want. Besides, I can leave the Asus running quite happily anywhere in a corner doing experiments while I need the Mac for work and life.
I'll report back with more findings.
btw, getting Infomap running on the Asus needed the same sym link to be put in as OSX (see previous post).
I'm quite excited to be working on this again. I have a whole raft of tests ready to apply - I just need the associate program to be running at a reasonable speed. From memory, I recall that Infomap worked the term comparison far more quickly than semantic vectors which was too slow for production use - and not being a Java head, I am the wrong person to optimise the code in my favour and I don't share the same aims as the developers which means my needs are a low priority.
Anyway, right now, the Asus has read in the text files in 20 minutes and is doing its maths. It's just a case of waiting now to see if it segfaults here too.
