I'd set the memory to something less than 128GB. 120GB max, maybe even 112GB
#22 Re: Search for prime gaps that can be found in the range 4e18 to 5e18
I set the memory at 120G and the 1st segment is now cranking. At the 5 minute mark the CPU is at 65-80% with 56G in use.
#23 Re: Search for prime gaps that can be found in the range 4e18 to 5e18
The 1st checkpoint came up and it appears it is less than double the speed of your laptop
32.67e9 vs your 18e9
The machine at 7505 seconds was at 4800245xxx so if the end result is 4810 and it is linear then it will take 85 hours to finish 4800-4810.
I see that the 2 CPUs are not being utilized equally. If I were to do it again then I would break the 4800-4810 into 2 WU and run 1 on each CPU. To do that you might need to launch the 2nd one from a different directory so it doesn't get screwed up with writing to the results file. It is now using 85G of memory.
By the way, it is using AVX2 because the CPUs are downclocked by 250MHz.

Sorry for coming back so late. Please find the linux binaries.
I did inquire the people running dual socket and they are running two instances of the client in separate folders.

Carlos, my systems are NOT using AVX. I tried 2 more systems E5 2695 V4 (72t) and E5 2695 V3 (56t) and according to the clock rate they aren't using AVX with the Haswell executable.
To confirm I ran BOINC Stop on both machines and looked at the clock rate ... ie on the V3 machine it was 2.8GHz. I then switched to Asteroids which is AVX and the clock rate dropped to 2.5GHz as it should.
When I start the Gap application the clock rate is the same as standard ... they don't downclock which means they are not running AVX/FMA3.
It is possible that the application is doing a lot of preliminary work and then doing the actual AVX calculation in bursts. I did notice that it runs for about 2 hours at 80% CPU usage and then does a 5 minute burst where it goes to 100%. Right after than it does the status update.
If that 64 thread machine is going to produce less results than 2 of your 4 core laptops I'm not inclined to continue.

Bryan, got confirmation from Thomas that: "Actually the AVX registers are only used once for the translation of the floating point input arguments (n1, n2) into integers." which follows the behavior you're experience. AVX is not being fully utilized. Apologies and please fell free to stop the running.

Okay Carlos and thanks for checking. I will be shutting it down since I don't see much benefit of running a machine of that class.

Anyone here with a fast intel quad (i7) or Ryzen (8C/16T) machine that could run me the following:

Here's the link for the 'First occurrence prime gaps' where it can be seen the works carried out since 1878.
http://www.trnicely.net/gaps/gaplist.html
Currently mersenneforum is working from 4000e15 to upper bound 5000e15 and the client can be used up to 16950e18. The code will have to be rewritten to be able to run beyond 16950e18.
This type of work is the kind you will be remember for decades...Please let me know if TSBT and SETI.USA are willing to support this project, there is no rewards, no BOINC points, no automate reservation system, it's all manual.
Thank you in advance,
Carlos

#32 Re: Search for prime gaps that can be found in the range 4e18 to 5e18
It uses all threads but it's not well optimised therefore you better run a client per 4 threads. You can play along with the client.
You can start with one folder running for example (16 thread machine, 32 GB):
start /low /min gap5_XXX.exe -n1 4500e15 -n2 4510e15 -gap 1250 -delta 155 -sb 24 -bs 16 -mem 28 -t 32
Or run several folders each one with the following command:
start /low /min gap5_XXX.exe -n1 4500e15 -n2 4503e15 -gap 1250 -delta 155 -sb 24 -bs 16 -mem 7 -t 4
start /low /min gap5_XXX.exe -n1 4503e15 -n2 4506e15 -gap 1250 -delta 155 -sb 24 -bs 16 -mem 7 -t 4
start /low /min gap5_XXX.exe -n1 4506e15 -n2 4508e15 -gap 1250 -delta 155 -sb 24 -bs 16 -mem 7 -t 4
start /low /min gap5_XXX.exe -n1 4508e15 -n2 4510e15 -gap 1250 -delta 155 -sb 24 -bs 16 -mem 7 -t 4
You can start with one folder running for example (16 thread machine, 32 GB):
start /low /min gap5_XXX.exe -n1 4500e15 -n2 4510e15 -gap 1250 -delta 155 -sb 24 -bs 16 -mem 28 -t 32
Or run several folders each one with the following command:

It's Xeon V4 (Broadwell EP) running at 2.8Ghz. Each of the 4 processes is getting a little better than 25e9 n/sec. Check my math but the 2 processes running the 3e15 ranges should take (3e15/25e9)/(24*3600), about 1.39 days, correct?

What are the different linux files for and which is run on which system? What's the difference between the static and non-static files?
EDIT: I figured out what the static executable was for.

New gap10 is 50% faster than gap5 since it now uses avx and a new algorithm. Went from 22e9 n/s to 31e9 n/s. Available ranges are:
7000-8000

Thank you Alez. Care to join? Odds now as we stand are higher to find a record.
Basically we need to replace the current C?C with new ones with less digits, currently all 19 digits are gone (missing latest update). Now at 20 digits, this means the majority of the C?C above 20 digits will fall. Even a 4C/8T can make a difference.

#56 Re: Search for prime gaps that can be found in the range 4e18 to 5e18
As the C?C became CFC, this means the prime gap with smaller digits, the flag -unknowngap can be increased which for the same search space the sieve step will be quicker. Steve, client gap12 is at least 50% faster than the one you used to run your ranges so 1000 will take only 2 weeks in your farm. Just to let you know. Time window to own some records is now on the 11-12 range.pinhodecarlos wrote: ↑Fri Nov 24, 2017 3:59 pm Thank you Alez. Care to join? Odds now as we stand are higher to find a record.
Basically we need to replace the current C?C with new ones with less digits, currently all 19 digits are gone (missing latest update). Now at 20 digits, this means the majority of the C?C above 20 digits will fall. Even a 4C/8T can make a difference.

Range 10000e15 to 11000e15 is now closed for reservations.
Open from 11000e15 up to 16500e15. Lot´s of records to be found here..

We are close to complete up to 11000e15. Open ranges now at 11e18 to 12e18.
I know this is a monologue but trying my best to have more external support.

BTW, -unknowngap 1382 was discovered on the range 1.1e19 to 1.2e19 which means for range 12000e15 to 13000e15 -unknowngap should be set to 1412. Still awaiting to know if we can shorter -m1 to -m2 space. This will give a boost on speed.

Don't feel bad. I'm sure more read it than ever comment. I would try and help out but my computers are an eighth of the world away just now.pinhodecarlos wrote: ↑Thu Dec 07, 2017 8:57 pm We are close to complete up to 11000e15. Open ranges now at 11e18 to 12e18.

Someone want to put up a quick easy how to run this all in one post and maybe some others will jump onboard ?
How to install, how to run, how to reserve a range, where to report it etc
Preferably covering both windows and Linux.
Let's see if we can give it a bit more prominence. I can also add it under the non Boinc projects with a separate sub forum, see if that gives it some more visibility.
The best form of help from above is a sniper on the rooftop....

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:
-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

#63 Re: Search for prime gaps that can be found in the range 4e18 to 5e18
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).

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.
