Default Team sieve #42: C161 from 4788:i5193

Tracking Aliquot Sequence 4788 index 5193.

Code:
# sieve with ggnfs lasieve4I14e on the -a side from 16M to 60M

Run the siever using the following command:
Code:
gnfs-lasieve4I14e -a 4788_5193.poly -o <output_file_name> -f <start_of_range> -c <length_of_range>
Add the -v switch if you want to see status updates every few seconds.
(I like to watch the progress.)

In case a restart is needed in the range, add the -R switch.
(All range numbers must be full decimal representations. i.e., 21M = 21000000)

Since ggnfs is single thread, multiple copies need to be run at the same time to utilize multiple cores. Be sure to use a different output_file_name for each range. Something like 4788_24M as signifying the starting point.

The output files can be placed at any of the file sharing services: DropBox, RapidShare, SendSpace, etc.

To start things off I'll take 16-22M.

Good choice going to 62M. I was hoping 60M would be enough. Now there is padding.

Each of these are 2M even though the filename is 16-17M.

16 & 17M
18 & 19M
20 & 21M

From what I remember of how distributed NFS (like NFS@Home) typically works, you don't get 100% completion in a reasonable time due to stragglers, so you overshoot a bit and then get the results at e.g. 99% completion.

I've got those results, thanks. I've removed dupes again and "Found 16403029 unique, 684212 duplicate, and 0 bad relations."

Note to all: 29-32M is still available.

I'll take 29M, leaving 30-32M for others. I'm getting ready to start a NFS@Home PP job.

I see 32-62M has reached the active queue but the first WU has yet to be sent out. Once it does, it can complete the entire range in a week or so.

Reserving 30-32M.
(An off-topic question: Is a Haswell core much faster (10% or more) than a Sandy Bridge core with respect to NFS?)
