Just to try.
Try to reduce the number of thread  per block from 128 to 64.
And if it works to double the number of block per grid using -g

GPUEngine.h:28

Code:
#define NB_TRHEAD_PER_GROUP 64

There is a typo in the code Wink

The errors remain.

Could you try this:
Code:
pons@linpons:~/VanitySearch$ /usr/local/cuda/bin/cuda-memcheck --tool memcheck VanitySearch -g 1 -check

On my Linux it does not work (too old hardware) but on windows it ends like this.

Code:
C:\C++\VanitySearch\x64\ReleaseSM30>cuda-memcheck --tool memcheck VanitySearch.exe -g 1 -check
...

I committed a new Makefile with debug option.

Code:
make clean
make gpu=1 debug=1 all

In debug mode no inlining is done.

But, obviously it is much slower.
So launch

Code:
pons@linpons:~/VanitySearch$ ./VanitySearch -g 1 -check

You can test with the release you have.
You can try:
Code:
VanitySearch -gpuId 0 -check
VanitySearch -gpuId 6 -check (On the 3GB)
Thanks Wink


Tomorow, I will try to set up cuda sdk 10 on a recent hardware (Linux) and see If I can reproduce the issue.

I tried your program with the parameters as shown in the sample + my username
Code:
-stop -gpu 1stortz

it ran, but just closed after finding it
did it generate the private keys into a file?
I am confused

Hello,

it ran, but just closed after finding it
did it generate the private keys into a file?
I am confused

To output the key in a file, use the -o option.
Code:
VanitySearch -stop -gpu -o key.txt 1stortz

Many thanks stivensons for the report Smiley

They are compiled with CUDA SDK10.
Thanks to test them Wink

Hello,

I would like to present a new bitcoin prefix address finder called VanitySearch. It is very similar to Vanitygen.
The main differences with Vanitygen are that VanitySearch is not using the heavy OpenSSL for CPU calculation and that the kernel is written in Cuda in order to take full advantage of inline PTX assembly.
On my Intel Core i7-4770, VanitySearch runs ~4 times faster than vanitygen64. (1.32 Mkey/s -> 5.27  MK/s)
On my  GeForce GTX 645, VanitySearch runs ~1.5 times faster than oclvanitygen. (9.26 Mkey/s -> 14.548 MK/s)
If you want to compare VanitySearch and Vanitygen result, use the -u option for searching uncompressed address.
VanitySearch may not compute a good gridsize for your GPU, so make several tries using -g options in order to find best performances.
Using compressed addresses is roughly 20% faster.

VanitySearch is available from https://github.com/JeanLucPons/VanitySearch

There is still lots of improvement to do.
Feel free to test it and to submit issue.

Thanks.
Sorry for my bad English.
Jean-Luc

Hello,

A new release of VanitySearch (1.9) is out:

Code:
Added -b option (Search compressed or uncompressed addresses)
Improved performance for loading large prefix list
Fixed difficulty calculation bug for prefix containing only '1'

Windows binaries: https://github.com/JeanLucPons/VanitySearch/releases/tag/1.9
Linux binaries: http://zelda38.free.fr/VanitySearch/ (Experimental)

Tanks to test it !

New version is slower on my pc (132 MKeys/s against 162 MKeys/s).

On my Windows, performance are the same than the previous release (Cuda 10).
Slightly slower on Linux (Cuda 8.0), from 39.5MK/s to 37.9MK/s.

Anyway,
Do you compile or do you use Linux binaries ?
Do you solved your problem ? I didn't manage to reproduce the issue yet.

I compile the source myself. No, my problem is not solved. I have only Cuda 8.0.


Some ideas for (maybe) a little speed improvement:


1) in __device__ void ComputeKeys (GPUCompute.h) instead of doing HSIZE times

Code:
ModNeg256(dy,Gy[i]);  <--
ModSub256(dy, py);

you could do:

Code:
ModSub256(dy, pyn, Gy[i]);

and you compute only once pyn:

Code:
ModNeg256(pyn,py);

2) instead of

Code:
ModAdd256(py, Gy[i]);

Code:
ModSub256(py, sy);

To sum up:

Code:
ModSub256(dy, pyn, Gy[i]);

_ModMult(_s, dy, dx[i]);      //  s = (p2.y-p1.y)*inverse(p2.x-p1.x)
 _ModMult(_p2, _s, _s);        // _p = pow2(s)

ModSub256(px, _p2, px);
ModSub256(px, Gx[i]);         // px = pow2(s) - p1.x - p2.x;

ModSub256(py, sx, px);
 _ModMult(py, _s);             // py = - s*(ret.x-p2.x)
 ModSub256(py, sy);         // py = - p2.y - s*(ret.x-p2.x);  


3) in __device__ void ModSub256 instead of

Code:
    if ((int64_t)t < 0) {
    UADDO1(r[0], _P[0]);
    UADDC1(r[1], _P[1]);
    UADDC1(r[2], _P[2]);
    UADD1(r[3], _P[3]);
  }

it would be better something like that:

Code:
 if ((int64_t)t < 0) {
    USUBO1(r[0], 0x01000003d1);
    USUBC1(r[1], 0ULL);
    USUBC1(r[2], 0ULL);
    USUBC1(r[3], 0ULL);
  }

(I'm not sure what C means, I suppose means with carry)

Another sub function, if you want to test it:


Code:
__device__ void ModSub256(uint64_t *rp, uint64_t *ap, uint64_t *bp) {

 
  uint64_t a0, a1, a2, a3, b0, b1, b2, b3, r0, r1, r2, r3;
  int8_t c0, c1, c2, c3;


  a0 = ap[0];
  a1 = ap[1];
  a2 = ap[2];
  a3 = ap[3];

  b0 = bp[0];
  b1 = bp[1];

Many thanks for the tips Wink
I will try this.

You don't want to try binary ? The libcudart.so.10.0 is also available from the given link. You do not need to set up cuda sdk 10 (unless a driver problem appears but this may work without installing anything).
You can just copy VanitySearch50 and the libcudart.so.10.0 in a directory and set the LD_LIBRARY_PATH.
Code:
export LD_LIBRARY_PATH=.
./VanitySearch50 ...

This is mainly to see if the problem is solved with CUDA 10 or if it comes from elsewhere.
