Monitor on NV does not help for CPU use... as far I know there is no workaround at least not without rewrite of opencl code

1070 + 1080 + intel GPU enebled

apha 0.4 try to mine on all three -> fail miner just close!

Disabled intel GPU in device manager, miner works fine

Please make option to disable GPU

PS: I guess miner is not so for NV as it use opencl and there is 100% on CPU per core vs GPU number

Intel GPU's are evil. GGS should ignore them. I will double-check.
There is a workaround for the infamous busy wait bug in NVIDIA's OpenCL driver, but it requires a ton of work.
You could avoid it by not attaching a monitor to the NVIDIA card, I think.

I was tracking down a really weird bug, but I finally hunted it down.
Oh, the fun of debugging a multi-threaded application...
I will run final tests and upload Version 0.0.5 shortly.

hi.
does anyone know how to change in old gg a 90-second timeout which leads to "stratum connection to pool interrupted"?
Try --failover-switch-delay 60
But it 60 sec by default.
I mean

 /* The protocol specifies that notify messages should be sent
     * every minute so if we fail to receive any for 90 seconds we
     * assume the connection has been dropped and treat this pool
     * as dead */

I found crutch but still uncomfortable.

I already tried two threads. It ain't that simple...
Waiting for update... At this moment with 1 thread per GPU and correct globalworksize (28*36) on overclocked RX 580 8Gb I have about 725 H/s with GGS. With GG and Claymore I have 800+ H/s. I think 2nd thread will increase speed to GG level.

You must add 2nd thread for each GPU for cryptonight - this increase speed.
I compiled your cryptonight version but it's not show estimated profit and current balance as on your screen.

The strange thing is that I never had good results with two threads as far as cryptonight was concerned.
Is there something I'm missing?

Whether you would see estimated profits etc. depends on the pool.
Yes, you missing something. All my cards 270X 4Gb, 280X 3Gb, RX580 8Gb on GG, XMR-Stak-AMD and excavator gives more 10-20% speed with 2 threads then 1 thread. Only Claymore miner works with 1 thread and gives high speed.
I don't think that it hard to add 2nd thread option. Just add it and try.

I tried nicehash pool and profits and balance not working.

i think you missing something, maybe it depends on the gpu?...i get much better results with with 2 threads too(rx580 8gb) and i know its the same for 470/480/570

maybe its something about memory usage...with claymore 10.2 i get good speed too with this new dmem setting, faster than sgminer/stak with 1 threads, but slower than sgminer/stak with 2threads

Waiting-waitnig Monero!

I cannot wait to get my hands with equihash again. I will wrap up Monero tonight.
By the way, the requested watchdog feature has been implemented already.

Monero mining seems to be working with major pools, at least on AMD cards.
Unfortunately, it is not working well on NVIDIA cards with too many incorrect results.
There must be a problem with synchronization. So much for cross-vendor compatibility of OpenCL...

Wolf's kernels are pretty interesting. They consists of 7 parts, and the second one is the most time-consuming one by a large margin.
I wonder if I could do something with the second one.

GGS will have the ability to tweak memory timings on the fly...
This means that GGS will allow to change memory timings without programming vbios? How it can be possible? If so that will be great! Experiments this manul editing timings through vbios programming take too much time.
Waiting for version with cryptonight to test.
Thank you for your work!

This feature is pretty experimental, so it may or may not work for you.
I like the idea, and I know for sure it works. I just need to do a ton of experiments and testing.

on the right track, but right now you can can get ~1k on rx 480 with GG Wink

That's with BIOS mods and overclocking, right?
Actually, GGS's kernels are pretty much the same as GG's, so it's a matter of tweaking, I guess.
Ubermix 3.1 bios mod for Samsung memory. No overclocking though

with options: --gpu-threads 2 --worksize 8 --rawintensity 1024


These options didn't work quite well with the original GG and stock RX 480, so it must be the BIOS mod.
GGS will have the ability to tweak memory timings on the fly, so it is theoretically possible to achieve the same hashrate.
We will see.
