I have problem with Bytom mining performance. My rig used to mine with 4x1080Ti. Performance was ok, almost 5K hash per card. Now I changed 2 cards and have 2x2080 and 2x1080Ti in the same rig. The 2080 performance is as expected, but sadly 1080Ti performance halved! I tried to run both pairs of cards as separate threads, but it's the same. Any help on this?

There is a confirmed issue that mining BTM with mixed 10 series and 20 series cards, which would cause the 10 series cards has much lower hashrate than previous versions.

Will be fixed in next version.

Volta's tensor cores don't support the INT8 mode supported by Turing's tensor cores, and BTM's tensority algo uses 8-bit matrix multiplication.

That being said, the @NebuTech devs could make a version specifically for Volta's tensor cores which used the FP16 matrix multiply mode supported by Volta, since you can encode INT8 numbers in FP16 format with no loss of precision.

yes, but there are other limitation other than operator type.

So do you have plans to add Volta GPUs support? It's very interesting how much hashrate Volta could be. Could it be profitable like RTX GPUs or it's just waste of money

No plans to support Volta GPUs. The price of Volta GPUs is higher that Turing, and even if the tensor core on Volta can be used to mine BTM, the theoretical peak hashrate is still only half of which on Turing's.

i hope this isnt dead

It's not dead.

We have several days off for Chinese new year.

New versions will come in few days.

I have a 2080ti, Logs in gets no error but shows 0.00 shares on btm.

Any help?

Dear developers do you plan to use rtx tensor cores to increase hashrate on other algorithms?

Tensor cores can only be used on matrix based algorithms.

There is no algorithm that I know for now other than tensority which has this attribute.

thanks for clearing that up

^Groestl algo has some matrix mult in it. But that algo is being hit by FPGAs already so might not be worth it.

Are there any improvements for the Titan V and Titan XP with v14.0?

Would the Titan RTX work for BTM?

also really wish we could open up volta tensors

Titan RTX should get a hashrate above 19,000

The capability of developing a volta version for BTM miner is one thing, more important concern for us is that it’s just not profitable for us to put time into this development.

Considering there are multiple algos, like cuck(at,ar)oo cycles and upcoming progpow, which are adopted by cryptocurrencires with much bigger marketcap, developing a BTM miner for a low user volumn market dose not make any sense.

Dear developers how can I contact you?

Hello Guys,

what is the chance that we will see the usage of Tensor cores in other algos? If so, is it possible that we will also see signifgicant increases in hashrate in other algos?

Thanks!

I know of one private miner used by a farm which was built to make use of Volta's tensor cores for BTM. If their devs could build it, I'm sure your devs could overcome any limitations to release a public miner for Volta as well.

What limitations are you encountering?
