It appears the latest numbers are missing the .fb file.[/QUOTE]

[QUOTE=pinhodecarlos;299697]I'm amazed by the fact that an Intel core i7 2630QM at 2.0 GHz with 8 threads clearly beats an Intel core i5 750@3.6 GHz with 4 cores and consumes a lot less when running msieve. I can't imagine how fast are the new IB processors. I think it's time to retire my core i5...:no:[/QUOTE]

So using the hyperthreaded "cores" gives you a significant boost over just using the 4 physical ones for the LA phase? Have you measured how much?

[QUOTE=Jeff Gilchrist;300131]So using the hyperthreaded "cores" gives you a significant boost over just using the 4 physical ones for the LA phase? Have you measured how much?[/QUOTE]

Question 1: I didn't do that test, I ran msieve with 8 threads so I can't tell you that 4 physical cores are quicker than 8 threads.
Question 2: The laptop during LA phase was, by estimated time, 2 hours quicker. The filtering phase ( 1 core/1 thread) was 200 seconds faster on the core i5.

I did not finish the LA phase.
The laptop cpu has a TDP of 45 W and the core i5 with default frequency has a TDP of 95 W.

This must not be my number. After the fourth attempt, I finally downloaded the data file in its entirety.

You have to re-edit .fb file into a .poly file.

Pace Nielsen is doing it but 2063_71_minus1 is free.
