There is an update available for the WW app! It features a ~3x speed increase and an increase in the software limit (2^62 -> 2^64)! Before this can be released, it needs to be tested.

A testing spreadsheet is here: https://docs.google.com/spreadsheets/d/1dh07hIbOgjcYxFVyXcm8YW3uoSmot63RRFjp8ex8DU8/edit#gid=131520259. To reserve a cell, post your reservation here. Then run the four test cases listed on the side and post your results (both the residue and whether the special instances were found). We're also curious what speedup you notice compared to the previous testing (ranges are the same size).

Thank mfl0p and Yves Gallot for the incredible update!

Notes:
For multithreading, add `-t #` to the end of the command line parameters, where '#' is the number of cores you want to run.
PSA credit and the "Volunteer Tester" role will be granted for test cases run.
While the range was quadrupled, the program is also faster. My rough estimate is WW will be running for 1-2 years, and this is quite unlikely to increase, though it will be considered in the future.
The residues from the previous app version are incompatible with this version. Don't get ambitious and try to use app_info.xml yet!

I can't edit, but I'll take nVidia Windows.

Looks like a 3x+ improvement over current production version.

- Similarly, I have removed most of the results from the results of the second test, but have included the md5 checksum for the file so that it can be confirmed that the output was correct.

Will the credit per unit remain the same? (please say yes!)

We'll probably increase the workunit size and the credit proportionally (meaning 3x workunit size -> 3x credit per workunit). Not set in stone, though.

Yes, approximately. Different GPUs will also have different amounts of speedup, so we haven't decided on how much we will increase each task by. I'll get it figured out after testing is done.

We'll probably increase the workunit size and the credit proportionally (meaning 3x workunit size -> 3x credit per workunit). Not set in stone, though.

We'll probably increase the workunit size and the credit proportionally (meaning 3x workunit size -> 3x credit per workunit). Not set in stone, though.

That means with a decent GPU like a 1660 I will get more than 1 000 000 credits a day? Is it really good to have few subprojects where it's a breeze to get to jade while generally it's a tough accomplishment? There's already this large gap between GPU and CPU subprojects, but this would be somewhat extreme.

Ok, so size was meant in terms of time required to finish?

I thought it was meant in numbers tested and with the 3x increase in speed that would increase credit by a lot.

For comparison, GFN-18 takes about 25 minutes for me and yields 1750 credits. WW yields 4000 for 15 mins. Both subprojects allow CPU.

Regarding credit on WW:

If the speed of the software changes, the credit for each task does not change.

If the size of the task, meaning the number of candidates checked, is changed, then we will adjust the credit proportionally.

This is consistent with how we usually award credit.

Haven't seen any AMD cpus yet, so here's a Windows CPU Multithreaded running an AMD Ryzen 5950X:

As usual, I ran some tests on one of my Intel iGPUs. I ran it on my 6006u's HD520, and everything worked without a hitch. Improvement was between ~3x to almost 4x in one of the tests. Very impressive!

As usual, I ran some tests on one of my Intel iGPUs. I ran it on my 6006u's HD520, and everything worked without a hitch. Improvement was between ~3x to almost 4x in one of the tests. Very impressive!

It's interesting, another OpenCL compiler is a good test.
On my computer, WWocl doesn't work on iGPU: unsupported OpenCL extension 'cl_khr_int64_base_atomics'.
The iGPU is an HD 630 and the driver is 23.20.16.4973. What is your driver?

I'm using 27.20.100.7987 under Windows. I do own an 8400 which has HD630, I can test it later once I eventually get back home.

Final test.
I searched (with a version of the program compiled with a larger threshold) for "almost-near-primes" and found:
18446736287849978869 is a Wieferich special instance (-1 +39003642 p)
18446742680598714497 is a WallSunSun special instance (+0 -59149319 p)
Both results are correct and close to 2⁶⁴.

The update is live! PSA credit and the "volunteer tester" role have been applied. Workunit sizes have been tripled, but runtime should remain about the same. There will be a mix of old and new tasks for a bit though. Thanks to everyone for the very quick round of testing!

I'm using 27.20.100.7987 under Windows. I do own an 8400 which has HD630, I can test it later once I eventually get back home.

If it runs on the HD 520, it will on the HD 630.
My computer doesn't want to update my iGPU driver because it is the latest version of the constructor and 64-bit atomics were not implemented in this release. Surprising because this is OpenCL 2.1 NEO and FP64 are supported. Not a real problem but I like to validate programs on iGPU, I already found a bug in genefer that was not detected with Nvidia driver.

This is consistent with how we usually award credit.

This is consistent with how we usually award credit.

So now I get 12 credits per second with a 1660 super for WW while I get about 1 credit per second for GFN-18. Might be consistent, but still a bit strange... Who came up with the initial 4000 credits per task?
