Hey everyone,
I am searching for smaler projects in the science/prime area to participate. Currently I am participating at primegrid and a private GFN13/14 server. In the last couple of days I read a lot about the sieving process with the mtsieve framework etc. here in the forum. I choose the Carol/Kynea primes because these a relatively small and fast to check and sieve. Setting up the MySQL and prpnetserver for multiple CPUcore workloads was no problem. Now I experience a problem with the import of the ABCfile from cksieve into prpnet. It does not seem to recognize the fileformat "ABC (130^$a$b)^22". The server is set to Carol/Kynea primes via the servertype=32. I tried the fileformat "$a*<base>^$b$c" from the abcfileformat.txt but this also does not work. Can anyone please explain what format type I have to set in the sieved file to be compatible with the prpnet import? I know that I did no reserve any range to be sieved, for now this is just for testing and playing around. I will do a proper reservation once I figured all out. Thanks in advance hunson.

Hey everyone,
I am interested in smaller scientific projects especially prime numbers that a fast to sieve and check. I did some reading about the sieving prp checking process here in the forum and now I want to play around with the software. The Carol/Kynea primes (http://www.noprimeleftbehind.net/Car...imesearch.htm) is my project of choise for now. I decided to set up a prpnetserver for fun and multicore workloads. Setting up the MySQL and prpnetserver was easy enough. When I try to import the ABCfile from cksieve into prpnet I get a error message which says something about a unrecognized format. Changeing the ABCfile according to the abcfileformats.txt (included in prpnet) from ABC (130^$a$b)^22 to ABC $a*<base>^$b$c did not resolve the issue. The prpnetserver is set to these primenumbers (servertype=32). Can someone please tell me which format the sievefile for Carol/Kynea primes has to be edited to to import it in prpnet ? Furthermore I did no find a "create_tables_mysql.sql" in the prpnet package, can someone please upload it ? I know that I do not have a reserved range for any sieveing, for now this is just for fun and curiosity. I will do so if I figure everything out. Thanks in advance hunson

not reserved, only done to n=50k after prime found as posted.

Finished my ranges
34: No primes where found up to 50 k 130: No primes where found up to 30 k 140: No primes where found up to 30 k The other ranges resulted the following prime numbers (checked with tp flag of pfgw) Quote:
Releasing all reserved ranges (34, 130, 132, 134, 136, 138, 140, 142)

I thought so, too bad.
Well at least these primes are documented now :)
