[XPM] [ANN] Primecoin High Performance | HP14 released!

[Trillium]

If you want to do profitable CPU mining, my tips are:

- Have a lot of hardware ready to go, sourced as cheap as you can
- Free / leached electricity helps. By leached I mean at work or low cost tarrifs, not coathangering your power box
- If you must pay for power, use newer CPU with fab sizes not larger than 34 nm. Newer CPU are amazingly more efficient.
- Avoid buying old servers from eBay or site auctions. Yes they're extremely cheap but they'll always be disappointingly slow, inefficient, and noisy.

Lastly but most importantly, you must sink a lot of time into researching and looking for new CPU coins, which means browsing the altcoin forum daily. You have to get onto the new coins as soon as they're out as that is always where the profits lay in the long run. The time you spend doing this and tweaking mining software/hardware may not ever exceed your profits if you put a value on your time.

Unless you are lucky your efforts will probably be in vain when compared to margins from scrypt/scrypt-n/SHA-256 coins and hardware.

What's sad about it? You think Doge has less potential than Primecoin?

difficulty is going up and price is going down, why?

HP14 released! This is a big release with a huge speed boost for CPU miners. Download links are in the first post.

Changes in -hp14:
 * Huge CPU mining speedup. Up to 73% higher chains/day on Intel's Haswell.
 * Developer fee is now 1% (-donationpercentage defaults to 1.0).
 * Sieve now uses the BTS instruction (same as RapidPrime miner).
 * Added compile-time support for using BMI2 instructions on Haswell.
 * Added compile-time support for SSE2 and AVX2 bitwise operations.
 * New extended sieve algorithm similar to rdebourbon's beta4 code.
 * New default values for the tuning parameters:
   . sievefilterprimes defaults to 14000 (up from 7849)
   . sievesize defaults to 1376256 (up from 917504)
   . sieveextensions defaults to 10 (up from 9)
 * Lots of other minor improvements.

Thanks Mikaelh. I will send you some tip the next time I open my XPM wallet -- blockchain getting too big.

Good update. Had it been released a few months ago it would have been a bomb. But difficulty is about to hit 11 and GPU miners can already produce almost 3 chains per day, per card (20x speedup)...

There is no future in CPU solo mining, I'm afraid.

[primer10]

Am I correct to say that GPU miners may be fast but they are working on primes with shorter length?

[Trillium]

per card (20x speedup)...

That is completely meaningless. You have to specify a model.

[Pinocchio]

Any decent ATI card... for 20x speedup, you'll need at least a 280x, but I would not be surprised to see additional and substantial performance gains in the future in favour of the GPU...

Guys, I have an associate that is running hp11 and he has described something odd. He remembers having two wallets, then one and now none when he moves to the addresses tab. He has three transaction records confirming his mining so where did they go?

how many this coin total number?
who can tell me

There is no limit.

However, mining rewards will drop, as difficulty goes up.

Block Reward = 999/Difficulty^2

Here is a place combining altcoins and gaming!  Really cool concept and of course it has integrated XPM!

If I had to wager I guess I would probably put my money on the fact that this coin has no cap.  Yes, difficulty keeps going up, and yes rewards may get smaller.  But the bottom line is there isn't a finite supply of them (like DVC) so I suspect the price will only occasionally experience brief up-trends on an otherwise downward trajectory.

There is no hard limit but probable is a cap of 25-55 million. See http://www.peercointalk.org/index.php?topic=2055.0

primes community is just so active?

[bengtåke]

Yes, very active. They might be over at the ppc forum or something

[donschoe]

Yes, very active. They might be over at the ppc forum or something

Yes the PPC/XPM forum is a nice resource.
