The Next Big Development for GIMPS

I'm probably misunderstanding something.

Uploads are ~100MB, a CERT download is just ~13MB.

I'd be grateful if you could explain precisely what I am misunderstanding.

The PRP proof that's being uploaded to PrimeNet as part of this new development, and the data that's being downloaded from PrimeNet for certification, are not the same thing?
Then what is being downloaded?

[Prime95]

The server does part of the proof certification, you are downloading for the final step of the certification.

Have you run the 30.x beta code?

Have you observed the emprical?

Ah, I see. I missed your previous reply before mine. Thanks.

How much work is the server doing in terms of cpu usage? Can it keep up when many more proofs starts coming in?

I am trying to upload a batch of proof files directly to the server with curl but I get the following error:

curl -user"al:passwd" -d "proof/107839943-8.proof" -X POST "http://mersenne.org/proof_chunk/?UserID=al&Exponent=107839943&FileMD5=112d40a10002f536ca8e64cb2bba48a0&Filesize=104857600"
{"error_status":401,"error_message":"Unauthorized","error_description":""}

I know I can use prime95.exe v30,2 to do that but I am running into problem with the extra dll's ("can't find ordinal in dll file", and does not tell me which one). I am running gpuowl in Windows so 'upload.py' is not convenient for me. I was thinking of writing my own script using curl.

Any ideas?

I have noticed certification files sort of hang-out in the Prime95 folder and are not sent close to the same time as the test results are. As far as I can tell, over 30 minutes. Any particular reason?

Have you tried George's separate standalone uploader program?
That works for me (usually). And when it times out instead, waiting to the next day worked. I'm putting together a list of ways at https://www.mersenneforum.org/showpo...0&postcount=26

Use version 30.3 it has the required .dll's included:
https://mersenneforum.org/showthread.php?t=25823

or download gpuowl:
git clone https://github.com/preda/gpuowl
and use the python script: gpuowl/tools/upload.py
Usage:
./upload.py <GIMPSusername> <prooffilename>

Version 30.3 should solve the DLL issue. Let me know if it does not.

The proof uploader wakes up once an hour (or at the start of the user defined time window for uploading).
