Thank you Alez.

All reservations are made through mersenneforum.org at:

range (1.1e19 to 1.2e19) - http://www.mersenneforum.org/showthread.php?t=22749

but I can reserve a big range and manage the reservations from here but I would prefer if people could go there and reserve the ranges. If not I can do it here.

How to run the client?

An example of a complete line of code for a windows emulator, on a small laptop might be: ./gap12.exe -n1 1.1e19 -n2 1.2e19 -n 1.1e19 -res1 3000 -res2 3100 -res 3000 -m1 1190 -m2 8151 -unknowngap 1382 -numcoprime 27 -sb 24 -bs 13 -mem 2.62 -t 4

or whatever you have named your .exe file
or what ever your reserved range is, taking care to make sure that -res is set initially to the start of the range
these variables depend on the capabilities of your computer

-n1: start of range
-n2: end of range
-n: start of range
-n1 1.1e19 -n2 1.2e19 -n 1.1e19 (fixed per range, what changes are -res1 3000 -res2 3100 -res 3000. -res=-res1 3000 start of block, -res2 end of block. Block goes from 0 to 8151.

Windows binaries:
gap12_exe.7z
cygwin1.7z

-mem 2.62 -t 4

-mem means how much memory you want to allocate
-t number of threads

For example for a 64 thread machine (64 GB) you will need to create 4 folders and run -t 16. Lets imagine for range 1.1e19 to 1.2e19 you want to split (-res1 3000 -res2 4000 -res 3000):

folder 1: ./gap12.exe -n1 1.1e19 -n2 1.2e19 -n 1.1e19 -res1 3000 -res2 3250 -res 3000 -m1 1190 -m2 8151 -unknowngap 1382 -numcoprime 27 -sb 24 -bs 13 -mem 14 -t 16
folder 2: ./gap12.exe -n1 1.1e19 -n2 1.2e19 -n 1.1e19 -res1 3250 -res2 3500 -res 3250 -m1 1190 -m2 8151 -unknowngap 1382 -numcoprime 27 -sb 24 -bs 13 -mem 14 -t 16
folder 3: ./gap12.exe -n1 1.1e19 -n2 1.2e19 -n 1.1e19 -res1 3500 -res2 3750 -res 3500 -m1 1190 -m2 8151 -unknowngap 1382 -numcoprime 27 -sb 24 -bs 13 -mem 14 -t 16
folder 4: ./gap12.exe -n1 1.1e19 -n2 1.2e19 -n 1.1e19 -res1 3750 -res2 4000 -res 3750 -m1 1190 -m2 8151 -unknowngap 1382 -numcoprime 27 -sb 24 -bs 13 -mem 14 -t 16

Everybody works on the same range but different blocks.

For the time being I would like people to try the client before making the project visible since clients are standalone, not internet connection needed, everytime a block is completed you must move the results files before starting a new block. Client resumes and has checkpoints in function of the computer speed (15 mins, my machine).

BTW, the client now takes advantage of avx instructions.

Thank you Steve for coming back to help as a little.
In the meantime we have open a new range for reservation with new flags. Should be faster to process. Range is 1.2e19 to 1.3e19 but previous one should be ran with old flags, they can’t be mixed up.

gap12.exe -n1 1.2e19 -n2 1.3e19 -n 1.2e19 -res1 3000 -res2 3100 -res 3000 -m1 1235 -m2 7854 -unknowngap 1412 -numcoprime 27 -sb 24 -bs 13 -mem 2.62 -t 4

Steve is on fire, so far three new records. Thank you. Now we need to wait for Dr.Nicely webpage update so I suppose it will happen after New Year.
