[Dev] NeoScrypt GPU Miner - Public Beta Test

ghostlander

Do the APU’s support OpenCL? My wife’s PC is due to get upgraded sometime soon, and that might effect what gets built.

Of course they do. Even old Llano with 400 pre-GCN units is a good thing to have. Kaveri with 512 GCN units is even better, though I still prefer 4 real cores of Llano to 4 CMT cores of Kaveri.

HD6970: 19.5KH/s to 50.5KH/s and no HW errors!

Thanks to a much better global memory management with burst writes. Also tried a trick with copying a workgroup buffer to local memory and writing back asynchronously to global memory through async_work_group_copy(), but it didn’t work out (36KH/s and 15% of HW errors). A 2.5x speed increase is something to celebrate anyway. Anyone cares to donate towards drinks, whores and blackjack? ;)

How it use? Don’t work for me with cgminer 3.7.8. Cards in rig: 6950,6950,6870,5870,5870. Drivers 13.12, Windows 7 x64 sp1

What is the content of your .bat file? I suggest to rename your feathercoin.conf and start with a simple 'cgminer’command.

Then enter the url, username and password of your pool when prompted and try that. If the miner works write the config file to disk and start tuning from there.

If it doesn’t work, I leave it to the Wolf0 and Avehre to find a solution

Replace this in the kernel:

/* NeoScrypt core engine:
 * N = 128, r = 2, p = 1, salt = password */
__kernel __attribute__((vec_type_hint(uint4)))
__kernel __attribute__((reqd_work_group_size(WORKGROUPSIZE, 1, 1)))
__kernel void search(__global const uint4* restrict password,
  volatile __global uint* restrict output, __global uint16* globalcache,
  const uint target) {
    uint glbid = get_global_id(0);
    uint grpid = get_group_id(0);
    uint lsize = WORKGROUPSIZE;
    uint lclid = glbid & (WORKGROUPSIZE - 1);

    __global uint16 *G = &globalcache[(grpid * WORKGROUPSIZE) << 9];

with this:

/* NeoScrypt core engine:
 * N = 128, r = 2, p = 1, salt = password */
__kernel __attribute__((vec_type_hint(uint4)))
__kernel void search(__global const uint4* restrict password,
  volatile __global uint* restrict output, __global uint16* globalcache,
  const uint target) {
    uint glbid = get_global_id(0);
    uint grpid = get_group_id(0);
    uint lsize = get_local_size(0);
    uint lclid = glbid & (lsize - 1);

    __global uint16 *G = &globalcache[(grpid * lsize) << 9];

It makes the kernel very compatible at -1% of performance.

does sgminer with wolf latest kernel work for 6xxx cards as it is? +using dll fix for drivers??

playground with kernels and miners is a little complicated now…

hard to keep on track

found something like this:

so i guess it will work?
AMD Embedded GPU and APU Driver 14.201.1009 for Windows 7/8

Thia is the latest graphics driver for AMD’s Embedded GPU and APUs. Windows 7/8/8.1 32-bit and 64-bit supported.

AMD APUs should work just fine in sgminer, in fact they are faster than Intel onboard graphics from what I have seen, but still very slow compared to GPUs.

Not feeling well, but this is something I’ve been working on (NSFW): https://ottrbutt.com/miner/neoscryptwolf-11132014.png

Ooohhh, new pictures… Um, I mean, good speed improvement!!

Looks like Freya has some new companions to play with :) Also, the speed improvements are looking great especially for the 290x! Hope you feel better soon Wolf.

Hopefully $15g makes him feel a little better… O0

triplef wanted to try it. If it works, it’ll be a miracle lol

If you can get it, go for it!!

LOL, not really, but I thought I’d make a funny comment on it…

Some people are, some aren’t, so I figured I’d post it.

Yeah, saw “ottrbutt.com” been the domain… I assumed there was gonna be yiff. Really well done too. Got one of my fav artists in there actually.

But yeah Wolf0, I’m the only one here interested in them I think XD

With all that said, if anyone has any issue’s I have no problem enforcing people to crop their screen caps appropriately… This really is a grey area, it shouldn’t be allowed but you have made NSFW visible and until it upset’s someone I have no issue’s.

I don’t understand those pictures on background but hey whatever someone makes happy I m fine with it. I m just afraid that someone will enter my room when I m looking at new sgminer testings :)

Anyway here is someone for you all, I contacted Wolf0 on private but he never replied. Key to better performance(280x) is xintensity 3 or rawintensity 6144.

Have fun and remember:

im getting HW…

what i am missing?

When people post “Key to better performance(280x) is xintensity 3 or rawintensity 6144.” without the rest of the settings they are using, it’s useless as that won’t work properly without the rest of the settings it’s combined with.

I think that because of the variety of settings people are using to get the max out of their cards, that in order to use a recommendation like that, that you would need to use the entire list of settings that are used to get that speed.
