I was CPU mining , but when GPU "arrived" I stoped ...

I didn't stop, my rate of finding blocks hasn't changed in the last 24hrs and I am still profitable (even with the price drop).

I would be very interested in how many coins a solo GPU miner is finding per day; pps numbers are difficult to use when a non-standard sieve is being used.

Regards,

It's a shame because this is one of the few coins that do actually useful work. Hopefully people will continue to mine even if it doesn't bring great profit for now.

Seems like we have to get the price up somehow.
I'll buy some GAP, but I don't have that much BTC to make a reasonable impact.

are't you all positive bunch  Cool shelf life of a crypto coin (any crypto coin) is beyond any exchange shelf life

seeing here some parallels with XPM , in terms of sell off. same people must be doing it, however difficulty level is holding up and primes are being found and at a high rate, don't think fpga yet as price is blocking someone from starting design/manufacturing process. for me GAP and XPM future lies years if not decades in advance, not poloniex short trades, both are very innovative in terms of computing number theory problems in the distributed fashion with a reward attached to it, just a little over year ago no one would even think about doing this, so you all have span of little over 1 year of history, unless developer steps aside which I have a gut feeling he won't GAP blockchain is going to grow as well as difficulty of network overall, public at large is still unaware (public at large is unaware about crypto in general!) media has 0 press releases on the subject and rest are some miners that got on AWS quick and sold it quick to recoup AWS cost + some tiny profit.. this is very weak strategy

I am a bit bitter self.. but only because I can not use GPU miner (NVIDIA system) but I should blame it on myself and attach IDE with C++ bring source cod up and adjust for that card.. instead of waiting for the world to deliver it to me

thank you for your attention

What are the optimal parameters
 
-s  --sieve-size        the prime sieve size

  -w  --work-items        gpu work items (default 2048)

  -a  --max-primes        maximum sieve primes (for use with gpu)

  -z  --queue-size        the gpu waiting queue size (memory intensive)



The current parameters should be pretty optimal.
To give you a range:

Code:
-s   form 100,000 to 100,000,000 default 15,000,000
-w   from  32 to 32000 default 2048
-a   from  1,000,000 to  100,000,000 default 30,000,000
-z   from 2 to 30 default 10

Dev Is it possible to reduce the load on the processor Angry

Currently only the primality testing runs on the GPU, the sieving still runs on the CPU.
Although it is possible to port the sieve to the GPU, it will probably take more time.

I could reuse eXtremal's fermat test almost without any changes,
but since Primecoin and Gapcoins sieving differs it will need a more deeper look into the opencl code.

Nope. Sadly I am getting the same error that q327K091 reported. I was using GFX 750 Ti.

ok got passed OpenCL compiler error, now this

Thats not a solution. We need more people to be interested in the coin.

I have proposed a more aggressive reward halving (this will be the last time i propose it) but i havent see anyone talking against or for it. No chat at all.

Another thing sure is needed is someone to build a small 'advertising campaign'. Send emails to crypto related news websites, ask other exchanges to add the coin, ask vendors to accept it, some twitter work etc... Generally someone for 'public image' and organising the community...

Maybe we should gather a bounty and give like 5-10 gaps for everyone who will translate the OP on his mother language if there isnt one already.


Its a good thing that difficulty is raising though Smiley

Well, then let's talk about the reward halving:

It wouldn't be much work to change it,
it's just that everyone would have to switch to the new client / wallet before the first halving takes place.

So, what do you think about halving the reward

  • every year
  • every half year
  • every three months


Also, I will give 25 GAP for everyone who will translate the OP into his mother language.

-5 is an out of resources error.
You could try to use
Code:
-w 32
to reduce the memoy load for the gpu.

What is "the OP" ? I can translate into Arabic and French

Every half year seems fine. Three months is too quick in my opinion.

I'll add another 25 GAP

I agree that every half year seems fine.
I was thinking 3 months but if we dont manage to gain more people interested soon enough so fast halving would be catastrophic.

I would like to have more people arguing about the matter. What miners have to say? What other holders have to say?

Also guys, i dont think its wise to give 50 gaps for every translation. I mean there are other ideas that can use funds.  Like a giveaway of gaps by tweeting something. A small bounty for people making some art/infographics/funny pictures about gapcoin. Probably a bounty for a second pool. A bounty for merchants that will accept gapcoin (they should probably need to have some trust and wait at least like a month to get the bounty)

Also i think we should popularize a phrase or something. I was thinking something like  'We dont need you to buy gapcoin. We need you to mine gapcoin!' because after all i personally want to be part of a record breaking!

Anyway i am just throwing ideas to stimulate some chatting Cheesy

I like to give 88 Gap for a cuda miner. Anyone who like that can add a few gap for the dev who make it possible.
