One difference is that the f siever allows composite special_Q with prime factors greater than 256 while the others use only prime special_Q. This increases the number of lattices sieved over a given range of Q values.

Over the weekend I did a trial run of Shi Bai's 3.428e15 polynomial using lasieve4I16e. Although Greg is using the f variant of the siever now which allows composite special_Q to be sieved (thus affecting total yield), I thought the results might still be interesting to some.
Code:
3.428e15 polynomial from Shi Bai tested with lasieve4I16e and the following parameters: rlim: 400000000 alim: 400000000 lpbr: 32 lpba: 33 mfbr: 64 mfba: 96 rlambda: 2.6 alambda: 3.6 start Q rels in Q roots in rels per Q roots in est. rels in est. cumulative Q..Q+2k Q..Q+2k Q root Q..Q+50M Q..Q+50M rels 150000000 3359 86 39.06 2637012 1.03E+08 1.03E+08 200000000 4295 113 38.01 2603558 9.90E+07 2.02E+08 250000000 4383 117 37.46 2575156 9.65E+07 2.98E+08 300000000 4606 126 36.56 2550438 9.32E+07 3.92E+08 350000000 3421 99 34.56 2535727 8.76E+07 4.79E+08 400000000 2945 88 33.47 2514663 8.42E+07 5.63E+08 450000000 3286 100 32.86 2504409 8.23E+07 6.46E+08 500000000 3637 118 30.82 2492256 7.68E+07 7.23E+08 550000000 2778 91 30.53 2481334 7.57E+07 7.98E+08 600000000 3154 105 30.04 2467955 7.41E+07 8.72E+08 650000000 3186 109 29.23 2461102 7.19E+07 9.44E+08 700000000 3120 110 28.36 2451406 6.95E+07 1.01E+09 750000000 3068 109 28.15 2444230 6.88E+07 1.08E+09 800000000 2027 72 28.15 2437199 6.86E+07 1.15E+09 850000000 2210 84 26.31 2429513 6.39E+07 1.22E+09 900000000 2478 93 26.65 2421418 6.45E+07 1.28E+09 Last fiddled with by jrk on 20120507 at 16:37

My mistake. I've been testing degree 6 for too long, and for it I played with 3LP on the other side (for some polynomials, both variants, but for this batch these were used):
Code:
lpbr: 33 lpba: 32 mfbr: 96 mfba: 64 alambda: 2.6 rlambda: 3.6 alim: 400000000 rlim: 400000000 Code:
lpbr: 33 lpba: 33 mfbr: 67 mfba: 96 rlambda: 2.6 alambda: 3.6

lasievea = gnfslasieve4I11e lasieveb = gnfslasieve4I12e lasievec = gnfslasieve4I13e lasieved = gnfslasieve4I14e lasievee = gnfslasieve4I15e lasievef = gnfslasieve4I16e The first four applications have never been used and are therefore suppressed in the app list on the website. Bottom line...the lasievef and lasieve5f applications use gnfslasieve4I16e, not gnfslasieve4I16f.

And lasieved / gnfslasieve4I14e would become used if RSALS were merged into NFS@Home

Well, there are obvious advantages to having a single NFS grid
For instance, a single flavor of binaries, and a single server whose BOINC software needs to be updated once in a while.

The compile currently only works on Linux. Make sure cweb is installed on your computer. Then, download the original source and extract it. Then from the file attached, apply the patch lasieve5_ggnfs.patch and compile with make gnfslasieve4I16e and you should have a GGNFS compatible binary. If you wish to create a BOINC binary (which you generally wouldn't) then also apply the patch lasieve5_boinc.patch to add in the BOINC API.

Is B200 already mostly sieved? I'm getting WUs for 2^10191 now, but the highest WUs for B200 I saw were about 140k.
