Approximately 71.5 hours on 2 threads Core i3-2310M with 4 GB memory for a 6.71M matrix at TD = 70 (didn't bother to try any higher densities since my laptop takes a long time to read relations and filter).

I have re-downloaded the file and still getting probably cannot build matrix at TD 120 looks like I will have to run at TD of 70 which will take around 87 hours as mentioned above. I have attached log for anybody of interest. It takes over an hour before I discover it cannot build matrix. I might try with a TD of 100 tomorrow before I run it at 70. If anybody can recommend another TD please go ahead

I typically reduce density by 4 each filtering pass until it works. If you're impatient, go by 10s: 110, then 100. There's nothing magical about 120 as a standard; it just-so happens that most jobs work there.

I got it to work with the TD of 100 is going to take about 50 hours instead of 87 odd. I will probably have the results for you in a couple of weeks as I only run for about 12 hours a day. Thank you for the assistance

I would be keen on taking C169_116xx849_11 If no one has reserved and nobody else is interested in it? .richs I completely understand if you would like this for your laptop It is a small 29 bit number. I would run this after C210_14073559_31 is complete. The LA phase has another 37 1/2 hours to go
