CCminer(SP-MOD) Modded GPU kernels.

[MaxDZ8]

So it would seem that the CPU needs enough virtual memory to match all the GPU memory in use. I can see a preallocation
strategy being better for speed but if the CPU is swapping to disk it would be slower than dynamic memory allocation.

this memory isn't used anymore once it has been allocated to the vram

While this is technically correct I can tell from experience some drivers will still keep the address range as reserved, apparently this has some benefits for driver mangling (I can see how assuming different range <--> different resource can help).
Beware, CUDA is way more than your GPU or CPU, sometimes it goes through some heavy magic.
How is the memory consumption being measured?

hmm... heavy magic...   (well magical stuff is just science which isn't yet understood   )
The compiler has a bit a life on its own and depending how things are written you might see a few magical tricks...  )

I have been using the nicehash miner for the last few days.
Not sure what is most profitable because the 980 rig is going x13/neoscrypt and the 750Ti rigs are going lyra2rev2.
Why are they choosing different algos ? If the miner itself should choose the most profitable algo all my miners should mine the same ?

power-to-hashrate ratio is likely different? Haven't really looked at the nicehash miner myself but that would make sense.

It's a fact that lyra2v2 hashes better on 750ti than 9xx when compared to other algos, so there are times when lyra2v2 is
most profitable with 750ti but another algo is highest with 9xx GPUs. Maybe the nicehash miner knows this and adjusts
its profit switching accordingly. You should post your question in the nicehash thread for a definitive answer.

that is correct, that's why you have "benchmark" - to test your rig and it mines accordingly. That is why for nicehash miner you should build rig of 1 type card.

How much hash does a 750Ti get on Lyra2REv2?

I get between 5000 and 5500 depending on the card and overclock

[bathrobehero]

Huh, I only get about 4.6 Mhs with about +100 Mhz.

The sp-modded lyra2v2 on the 750ti is almost as fast as the DJM34 opensource kernal on the 960.

No Linux

My code will almost turn your 750ti into a gtx 960.

I haven't submitted anything to github in almost 2 weeks now.  I am taking a break.

hashpower is having problems: it happens periodically because the software is unstable and there is no constant maintenance going on (the same for ffpool).

griimp would be completely stable AND ongoing ...

Ok, i have been building my rigs like that so i should be ok then. Thanks
