Just built 32-bit versions (which I hope nobody is using!) and 64-bit NT service version.


This is the first time I've built these since my Mac died and I'm now on Windows with a new Visual Studio compiler.


A MacOSX port will be difficult. I'll have to steal the wife's computer.

I've joined the v30 beta testing a few days ago, with v30.3 b2 on a colab instance, working on PRP-CF candidates. So far, so good, apart from the last candidate who has entered an endless loop of
Code:
[Work thread Aug 20 10:55] Iteration: 10488602 / 10489856 [99.98%].
[Work thread Aug 20 10:55] Gerbicz error check passed at iteration 10489826.
[Work thread Aug 20 10:55] Generating proof for M10489607.  Proof power = 8, Hash length = 64
[Work thread Aug 20 10:55] Root hash = D9FEACD9545125105C0A88E19768DF99EA43BF97B183A15F42454E8569216911
[Work thread Aug 20 10:55] hash0 = 772F19B5FDFDB1A5
[Work thread Aug 20 10:55] hash1 = FA82BB6558F585A1
[Work thread Aug 20 10:55] hash2 = FBA62EA2942D2DCF
[Work thread Aug 20 10:55] hash3 = C35FC946454B1C33
[Work thread Aug 20 10:55] hash4 = BABA2FED3B34B207
[Work thread Aug 20 10:55] hash5 = 8CCFECCFA556DE29
[Work thread Aug 20 10:56] MD5 error reading PRP proof interim residues file.
[Work thread Aug 20 10:56] Waiting 5 minutes to try proof generation again.
[Work thread Aug 20 10:56] Waiting five minutes before restarting.
probably because the colab session expired a few iterations before completion, and maybe left some file in an inconsistent state.

results.txt contains a bunch of
Code:
MD5 error reading PRP proof interim residues file.
every 5 minutes for the last couple hours. There's no entry in results.json.txt so far for that exponent.

How do I get out of here? A restart from scratch?

TIA

Default phantom assignments

Recently got a TF assignment listed as assigned in a colab mprime instance, unexpectedly, in .https://www.mersenne.org/workload/.
Code:
Factor=(AID),242692117,71,72
I'll probably throw that minnow back. Especially since it does not appear in an actual worktodo file.
The same instance allegedly had been given a PRP assignment that does not appear in worktodo.
Code:
PRP=(AID),1,2,98497291,-1,77,0,3,
There's no record of those assignments in prime.log.
Both indicate as assigned 2020-08-19. Had another internet outage yesterday, but I would not expect that to affect colab instance interaction with PrimeNet.

All my colab mprime work preferences are set to 150 (PRP).

Not currently, but might fire up some smaller silicon space heaters with whatever is the current 32bit version in a few months. Certs might be just the right size for those.

Set MaxProofgenWaits=1 in prime.txt

The default is to try proof generation for 2 days before giving up (in case the file is on an NFS mount that is offline).
It is on my to-do list to tailor the wait time to the error. A file open error might wait two days, while your MD5 error is
unlikely to get better - maybe try just twice.

Got a new MD5 error: MD5 of downloaded starting value doesn’t match, will retry later blablabla, and then aborting. Using latest version of prime95.

I am seeing something that looks odd. Every hour Prime95 stops a worker and restarts "to do priority work". That would be great if there was any in the queue, but there isn't.
It is only checking in with Primenet for priority work (cert) once every 6 hours.

Can you send me the worktodo.txt file? THanks.

I am still running 30.3 build 2 on my computers so I need to upgrade them all to build 3 this weekend. Today one of my computers got a MD5 error.

This is when it started:

[Work thread Aug 21 06:50] Restarting worker to do priority work.
[Work thread Aug 21 06:50] Stopping primality test of M54082711 at iteration 39137183 [72.36%]

[Work thread Aug 21 06:50] Setting affinity to run helper thread 3 on CPU core #4
[Work thread Aug 21 06:50] Setting affinity to run helper thread 2 on CPU core #3
[Work thread Aug 21 06:50] Starting certification of M1158401 using type-1 FFT length 56K, Pass1=224, Pass2=256, clm=4, 4 threads
[Work thread Aug 21 06:50] MD5 of downloaded starting value does not match.
[Work thread Aug 21 06:50] Aborting processing of this work unit -- will try again later.

Is there a file you want me to send or should I just upgrade to build 3 and start up again to see if that fixes it?

Strange thing is... this exponent does not show up in my assignments list but it does show up in my worktodo.

Cert=UID,1,2,1158401,-1,18101

Do upgrade to build 3.

The error message is poor. The problem really is that prime95 is unable to get the starting value because the assignment is invalid. I've fixed the error message in build 4.

In build 2, this error will continue forever. In build 3, this error will happen 8 or 10 times and then the assignment will be removed from worktodo.txt.

I don't know why the assignment didn't "stick". It apparently was later assigned to me and I've already finished it.
