Nice job, is this limited to only 4 Vega per motherboard like xmr-stak is, as well? Does it play nice with mixed gpu rigs with nvidia and amd?

Thanks! The app should have no limit how many GPU used in parallel, probably more a driver issue.

Currently it is only one GPU per instance. One can select with "--opencl n" the OpenCL plattform to use (Nvidia, AMD, Intel) which number is the correct one is probably experimenting. And with "-G  x" which device to use. There is no programmed limit how many instances one can start,  One  process needs only 100 MB memory when running.


After testing it says [Suspicious link removed]pute driver not installed. The blockchain driver is all I have installed, is this still miner only working for one gpu?

Oh, which version of the blockchain driver do you have? (I only know of the 17..30.1029 Beta from Aug 23).

Yes, only one GPU per instance (maybe gone change that) and only Vega GPUs, because of the simple fact I only have those and my goal is to get the most out of it. There are no plans to support any other cards, beside maybe the RX 480/580 but it never will be a generic miner replacement...

Ok as long as it doesn't throw an error in a mixed gpu rig then that's fine. Xmr-stak refuses to play nice with Vega and nvidia running on the same machine even when using the amd stak only it will throw an error. If your miner just ignores nvidia that's fine for me.

I'm using the same compute driver, I'll try a ddu uninstall/reinstall and retry today. If I run into any issue I'll report it.

Update to version 0.4

Cast XMR Version 0.4 (2017/10/13)

  - performance optimizations result in 1 - 2% higher hash rates
  - reduced dev fee to 1.5%

has anyone tried this yet? How's the wattage from the wall?

2050 H/s on the screenshot looks nice, but what are teh settings of the card? AS its not that much higher than what can be done with xmr-stak.

Also, whats the hashrate without hbcc?

And 1.5% fee is a bit too much.

Yes, it is faster than xmr-stak-amd by 50-70 H/s for a single card (1925-1950 H/s) but I start a second copy, the performance of the first one drops by 200 H/s to 1750 H/s. Do you see this?

Only supporting single GPU per instance is a huge issue.  Also, do you plan on adding an api, or at least remote webpage?

hm, is "AMD CrossFire" turned off?

I am testing with a Vega 56 and 64 in parallel, sorry, can't reproduce. Both keep there hash rates and don't mind if its neighbour is started or stopped.

same issue here, crossfire off, running 1 vega 64 and 1 vega 56 and hashrate drops as soon as second gpu starts.

Ok, planning to support multiple GPU per instance. Personally found that running on instance per GPU very stable and more flexible, but there seem some reports that it does influence the other GPUs. Should be no big deal to implement.

Which kind of API would you suggest? Is there an standard?

"-G  x" dont working

-G select the GPU

with

"--opencl x" one selects the openCL plattform, default x=0 which in your case seems to be the Intel OpenCL driver.

Please try:

"--opencl 1 -G 0"

1 GPU per instance, yes.

But you can run as many instances as you like.

So start a new terminal and run "cast_xmr -S [server] -u [wallet address] -G 1" to start a second instance mining on your second GPU and so on for 3rd GPU....

and the hashrates are same? Can anyone tell the hashrate on card with not enabled HBCC?
