All About BTC, LTC, ETH mining as well as other alternative crypto currencies
Now, more than a day since the release of a GPU miner for AMD graphics for mining the previously announced as CPU only crypto Heavycoin (HVC) is available, surprisingly the price of the crypto is still at high levels. The release of GPU miner already made the mining of the coin with CPU pointless, and the coin is already not so easily mineable with GPUs with the network hashrate already pretty high. Mining HVC with AMD GPUs however may be worthwhile for some more time if you have some AMD Radeon cards to spare if the exchange rate does not start to drop. We still haven’t gotten a release of a HVC miner for Nvidia that uses CUDA, but the author of CudaMiner is working on such software. The interest in Heavycoin is still quite high and you should not be dismissing it so easily.
Heavycoin (HVC) is a recently launched crypto coin that can be mined only with the CPU, but apparently it is not impossible for a GPU miner to be created for it as well like with many other coins that started as CPU mining only. The key of the coin being “CPU only” is the use of multiple crypto algorithms – SHA-256, Keccak-512, Grøestl-512, BLAKE-512. But if you port all of them on the GPU you can achieve considerable speedup than what is possible with the CPU only mining, however for the moment there is no GPU miner available for HVC. The author of CudaMiner has reported some success already, note what he has posted in the bitcointalk forum about his work on a GPU miner for HVC (not CudaMiner, but a separate project):
we’ve accelerated 4 out of 5 hashing algos for HVC, but the last one (Groestl) is causing us a bit of trouble. Our first port is actually slower than the CPU – at least on my system.
Running Groestl on CPU and the rest on GPU I am getting an 800% performance boost vs. running the CPU alone.
Multiple CPU threads can even share a GPU ;)
Note that overall HVC is *not* CPU-only. They really need to change their advertising, and change it quickly. Whatever they did to SHA256 to turn it into a “GPU and ASIC resistant” HEFTY1 algorithm – it didn’t work as they intended.
