The ccMiner software miner for Nvidia GPUs has received an update to version 0.7 (source) adding support for Jackpotcoin and Myriad-Groestl. The new official release contains multiple versions for various GPUs, but do note that currently older Compute 2.0 hardware is not yet supported. Our test has shown a hashrate of about 7-7.2 MHS for mining Jackpotcoin on a single GTX 780 Ti GPU, so the performance you can expect mining JPC on Nvidia hardware is better than what the AMD GPU miner for JPC can currently provide.
Jackpotcoin (JPC) is a new crypto coin that uses a new hash algorithm called Jackpot Hashing Algorithm (JHA) and thus requires special miner software in order to be mined. The coin has a CPU miner available, but we are going to be skipping this one as there is also a GPU miner available already. The OpenCL miner for Jackpotcoin is based on the official sph-sgminer, but since the official release is not yet available with JPC support you need to use the fork for Jackpotcoin for now (source code). we have compiled a windows binary from the latest source that you can download below, our test on a single Radeon R9 280X GPU showed a performance of about 2.2-2.3 MHS mining Jackpotcoin, so it seems that Nvidia is currently the better choice for mining JPC on the GPU.
