Hey,

thanks for your quick response.
I do not want to seem inpatient for also writing this forum post, your eMail went into the spam folder :/ additionally I had a feeling that some persons might have left and that the eMail will be unanswered.

Resetting the password worked ! Thanks.

Hi all,

I am participating in a small prime search project and recently found a prime which might me suitable for submission into Chris Cadwell's prime pages.
Until now I only found primes on primegrid and the admins here created an account and submitted the numbers to the database, so I already have a 'prover account' there (https://primes.utm.edu/bios/page.php?id=2648).
Now the problem is, that I would like to submit my found prime under the same prover accound as the numbers found with primegrid but I do not have a password or the correct eMail address to send my a new one.
What are my options to 'claim' my account at https://primes.utm.edu ?

Thanks in advance.

Hey,

for now I am participating at the GFN-13 / 14 project ! Thanks for the suggestion.

The though that I search a range for prime numbers myself (have not decided on the form yet) is very appealing though, but I have to do some serious research about the number ranges of different projects. I do not want to overlap with other projects.

Thanks for all the suggestions.

@Kellen:
Thanks for the quick reply.
The suggested project seems interesting. To register I need a invitation code though.

Maybe I choose the wrong word when I said "insignificant". Surely the small numbers are scientifically interessting, but they will not be listed in Chris Caldwell's database ;)

The manual sieving and testing process sounds interesing too. But before I start I have to do some reading and testing ;)

Hey everyone,

I love science and research in my personal / professional life and at BOINC.
Quite a while back I used two old computers in the workgroup at uni to find prime numbers in the prpnet-project. I found quite a lot of the small b*2^n+1 (n ~ 50000) prime numbers, since the check even at those old machines only took about 10-20 sec :)

Now I am wondering if there is another project out there with small "insignificant" primes or other scientific relavant tests to preform with similar short workunits? Does anybody know of a project that meets this criteria?
It is not the fame I am after, it is more the urge to help science / complete something etc. with the little computing power I have (1 Machine). Surely my contribution to primegrid helps, but is rater insignificant compared to "the big guys". And although I am crunshing my workunits at primegrid no matter what, it would be nice to find something once in a while :) Therefore the search for a small side project.

Any suggestions are welcome.

kind regards

Hey,

I still got a lot of problems with prpnet on my linux machine (Ubuntu 10 and Fedora 15).
As someone suggested I set the debuglevel to 0 and additionally I set the logging to -1. Unfortunally this did not solve the problem. The "segmentation fault" still occurs after 1 or 2 WUs of PPSlow and then the computer reboots.
I checked the 'messages' file in /var/log and found the following:
Jun 22 08:44:38 moc3 kernel: [ 417.233736] prpclient[1785]: segfault at a ip 00d71ab0 sp bf8a77ac error 4 in libc-2.13.90.so[d2a000+188000] Jun 22 08:44:39 moc3 abrt[1813]: saved core dump of pid 1785 (/home/stephan/prpclient-4.3.0beta-linux_32/prpclient-1/prpclient) to /var/spool/abrt/ccpp-2011-06-22-08:44:39-1785.new/coredump (667648 bytes) Jun 22 08:44:39 moc3 abrtd: Directory 'ccpp-2011-06-22-08:44:39-1785' creation detected Jun 22 08:44:39 moc3 abrtd: Corrupted or bad dump /var/spool/abrt/ccpp-2011-06-22-08:44:39-1785 (res:2), deleting Jun 22 08:44:45 moc3 kernel: [ 423.591786] prpclient[1816]: segfault at a ip 007deab0 sp bffb558c error 4 in libc-2.13.90.so[797000+188000] Jun 22 08:44:45 moc3 abrt[1823]: not dumping repeating crash in '/home/stephan/prpclient-4.3.0beta-linux_32/prpclient-1/prpclient' Jun 22 08:45:50 moc3 kernel: [ 489.185948] prpclient[1828]: segfault at a ip 00ea5ab0 sp bf8babbc error 4 in libc-2.13.90.so[e5e000+188000] Jun 22 08:45:51 moc3 abrt[1835]: saved core dump of pid 1828 (/home/stephan/prpclient-4.3.0beta-linux_32/prpclient-1/prpclient) to /var/spool/abrt/ccpp-2011-06-22-08:45:50-1828.new/coredump (667648 bytes) Jun 22 08:45:51 moc3 abrtd: Directory 'ccpp-2011-06-22-08:45:50-1828' creation detected


If I understand this correctly it isn't the prpclient which causes this, it's the libc from linux !

Does anyone have a suggestion how to solve this problem ?

Thanks in advance!

Tanks
