Prime Constellations 2
Hi Math People
Many of you may not know what prime constellations are. They are a subset of the ktuples. Please see this reference. http://mathworld.wolfram.com/PrimeConstellation.html Also, I have written a webpage regarding Prime Constellations. https://sites.google.com/site/primeconstellations/ Additionally Tony forbes has written a webpage http://primerecords.dk/constellations.htm Hurray for Dana. Dana has written a software that will find prime numbers in prime constellations. He has made a list that is part of the Online Encyclopedia Of Integer Sequences (OEIS). See for example http://oeis.org/A213601 a list of 12tuplets. The search software has been released. It is just not advertised the right way. Can someone point me to a software that runs on windows64 and can list prime numbers that are in ktuple patterns? I want to augment the OEIS more. Regards Matt

Strawberry Perl plus download of latest code with the included cpan command suffices to use my software on Win64, including the threaded example script that will use all your cores. Alternately I could write a 20 line main() that read the parameters and called the function without using Perl  I would just need something to compile as a static binary.

Using the 2310*i+997 to select and checking isprime for the constellation comes up at 6778 times slower than my program on a single thread. You need to expand your solution set from just "I can use parfor!". Bigger primorials will help, plus sieving. As for parselect, we don't want to generate all the primes and filter them. We'll be running to 1e23 or so at some point. The set of acceptable residues is much less dense than the primes.

There is nothing more dangerous than little knowledge, sm88. A person can juggle jargon without understanding it for all day long (and even create a feeling in bystanders that a meaningful conversation is going on), but you should stop talking for a minute and listen to what DanaJ is saying. He is saying that thinking that simply calling parfor is a meaningless.
Saying that "I can use parfor!" is the same as the proverbial example of getting 40 virgins to produce a child in 1 week, or claiming that to build a house in 1 minute you only need 36 thousand hammers and strike them all at once.

Hi Math People
Thank you for your comments. I will repeat my request. I would like an executable program that will be able to find prime constellations. Private message me and I may be willing to pay money $. Regards Matt

Matt's take at prime constellations redux
Hi Mersenneforum,
Attached are probably my last efforts on prime constellation mathematics. Regards, Matt
