oh please.

Cute idea and it's going to make the GPU fun, but this is a bogus claim.

Process roughly 4096 keys at a time in 16 different workgroups, each working on a specific algorithm, shuffling the keys between them as they switch between rounds. Requires a little more attention paid to global memory use because the keys are probably too big to fit in local, but there's nothing fundamentally hard about this coin.

Sorry, we don't get it, could you elaborate? Especially on how are you going to synchronize these workgroups and what do you mean by shuffling the keys between them? Shuffling like moving them around in a global memory? Or perhaps draw the general idea, a picture would make it more clear.

1. Have 16 regions of global memory, one per hash function to compute. Each region can store, say, N keys.
2. Define a function that groups keys by their low-order 4 bits using local memory, for a workgroup. Call this put_keys_in_bins().
   The result of calling put_keys_in_bins is that all 256 of the keys computed by a workgroup will be placed into the appropriate regions of global memory.
3. Compute a lot of sha512 hashes for a lot of keys and call put_keys_in_bins().
for i = 0; i < 16; i++ {
   for algo = 0; algo < 16; algo++ {
   invoke hash_algo on bin[algo]
   put_keys_in_bins for all of those keys again.
   }
}

I'll stop doing your homework for you at this point. There are plenty of GPU devs who could do this. the choice of Echo makes it a little problematic for C&C to destroy this coin in a few days, but if anyone would like to place bets.... :-)

OK, we get it now. Looks promising, we will try to apply this optimization in a GPU miner.

I've got a python module ready for testing .. I'd just need a cpu/gpuminer with your algo implemented, let me know or pm me when you got something, so I can set up a pool.

interesting.
lets wait and see how long it takes before a gpuminer come up.

Well I managed to mine 3700RLT on a first gen Core i7 before the difficulty jumped. Not too bad, thats 74 blocks. That instamine was fun, thanks devs.

Mining with the wallet on the same rig mining another scrypt coin lowers my cgminer hashrate by almost 50%. This doesn't happen with any other coin I mine using a standalone CPU miner.

Thats what I'm doing. I have one wallet on each of my rigs and one on this computer. Grin

To fix the 50% problem just mine with 1 less CPU thread.

How do you change threadcount on the wallet debug window?

setgenerate true 4 or whatever amount of cores you have.

Thanks that worked. I use gen=1 in the wallet conf to automatically start mining. Is the any way to set the number pf cores automatically using the wallet conf file?

Yup, that one is easy too. genproclimit=4

Thanks. I'm mining on a dual-core rig. Mining with standalone cpu miners I can run the -t 3 setting without affecting the hash of another coin using cgminer. Mining with the wallet I can only set it to 1 without lowering the hash of the other coin so i'm guessing you can only set the number of cores when mining with the wallet, not the number of cpu threads (2 threads per cpu core) like you can with a standalone cpu miner.

sorry won't mine a so called cpu only coin, made by a gpu miner dev. Grin

(who will release a bad gpu version while keeping for him the good... may-be not true but there is always a risk..)

hmm and whats the use - innovation - general idea ?
thanks but no thanks!

We felt sorry for CPU miners after creating so versatile GPU miner for CPU-only coins, so now we created a (hopefully) true CPU-only coin.

oh please.
