Arrow GPU sieving drive part III: k<10000 n=3M-6M

Our previous GPU sieving drive part II, which covered n=2M-3M for this k-range, has been moved into BOINC at [url=http://www.primegrid.com/], like the n<2M sieve before it. The non-BOINC side of things has now progressed to the n=3M-6M range.

For this sieve, the larger n-range of n=3M-6M (rather than just 3M-4M) was chosen since the 2M-3M sieve will keep BOINC busy for a good while, and thus we won't be quite as rushed to get the next range ready for it. Thus, we can combine 3M-6M and do it in one fell swoop. ppsieve and tpsieve scale such that sieving time is inversely proportional to the n-range; that is, n=3M-6M will run at exactly 1/3 the speed of n=3M-4M.

As last time, we will be sieving with tpsieve, and this will cover both the Riesel and Proth sides since we effectively throw in one of them for "free".

I will reserve ranges from the primary reservation thread in the PST forum and distribute them here. The reservations table for NPLB's ranges ONLY follows below; see PST's thread for the overall canonical list.
Code:
P-range         reserved by     status
  0T  - 20T     PST forum
 20T  - 30T     PCZ             complete
 30T  - 40T     PST forum
 40T  - 50T     PCZ             complete
No ranges current available in this forum due to lack of activity.
If you plan to contribute at least semi-regularly here, post here saying so
and I (Max) will reserve another range from PST to divvy out here.
Otherwise, you can just reserve ranges directly from the PST thread
(linked just above this box).
I will follow this up shortly with another post detailing how to participate in this sieve.

Default Instructions for participation

To participate in this sieve, follow these steps:

-Download the appropriate version of tpsieve for your computer.
The CPU and CUDA versions can be downloaded at ppsieve software as before. The CPU version of tpsieve is bundled along with CPU ppsieve (ppsieve-bin-*.zip). For CUDA, download "tpsieve-cuda-*.zip". For OpenCL, download this--it's bundled with ppsieve like the CPU version. Yep, you read that right. tpsieve is now available for OpenCL!
Note: CUDA users will need the cudart-2.0 libraries in a place where tpsieve can see them. They are from a slightly older-than-latest version of the CUDA toolkit, so they probably didn't come with your installed CUDA toolkit. For Windows, download cudart.dll and plop it in your tpsieve folder. For Linux, download libcudart.so.2 for 32-bit or 64-bit and stick it in your CUDA libraries directory (probably /usr/local/cuda/lib/ or /usr/local/cuda/lib64/--at least that's where it is on Gary's machine).

OpenCL (AMD/ATI) users will need to download the ATI Stream SDK and read the instruction manual PDF. You do need to read the PDF since it is apparently not exactly a trivial process.

-Extract tpsieve to its own folder somewhere.

-Reserve a range from this thread.

-Run the appropriate command line for your tpsieve version and range. Quoted from John at the PST forum:
Quote:
PPR6M will have a command line as follows

tpsieve-(version) -p##G -P##G -k5 -K9999 -n3M -N6M -ffppr6M_##G-##G.txt -t# -M2 -T -q
-When the range is complete, upload your factors to http://pgllr.mine.nu/sieves/ppse/factors/. If you have trouble uploading, email your factors to max@noprimeleftbehind.net and I'll get them to where they need to go.

-Rinse, lather, and repeat!

Max
