C223_138_124 is in LA, full factorization expected by May 15.

Then I will start on C174_139_129.

GW_6_317 is factored.

Code:

Wed May 06 04:19:08 2015  p96 factor: 142575350932586923572459715968369859864433335753858113536214180102844323344718717798355424347637
Wed May 06 04:19:08 2015  p119 factor: 31896646169190223257187540825089310249605651327526535302353745505614967522059055131685585831588300058915185250930943687

LA took ~121h on Dual Xeon E5-2620. td=116. 15.7M matrix. Used 2x 6 threads as it turned out to be faster than 2x 8 threads.
Log here and as attached file.

I can take GW_8_272. ETA is this Sunday.

Alright

For now, I used your 'jyb' handle, for both your reservation and for information about ECM pre-processing of homogeneous Cunningham numbers; would you prefer something else ?
