[Jean_Luc]

The increase of stivensons seems rather normal, but 350% seems strange !
May be there is a problem...
Does it work fine ?
If you try to search the same prefix several times, you note each time the percentage when the prefix is found, the average should be around 50%.
It is the case ?

[arulbero]

Definitely there is something wrong.

Your git clone is up do date ?
git pull

Did you clean before making ?
make clean
and make gpu=1 all

On my config the -check is ok.
It looks like the problem I had last time when the GPU code was wrongly generated.

Ok
Could you try to edit GPUEngine.cu and to change the stackSize to 49152 line (48K) line 1371.
I doubled the group size and I missed this.
Does it improves something ?

Code:

  size_t stackSize = 49152;
  err = cudaDeviceSetLimit(cudaLimitStackSize, stackSize);
  if (err != cudaSuccess) {

Ok

Could you try to noiline to 2 ModMult, also in GPU/GPUEngine.cu:

Code:

Line 510: __device__ __noinline__ void _ModMult(uint64_t *r, uint64_t *a, uint64_t *b) {
Line 560: __device__ __noinline__ void _ModMult(uint64_t *r, uint64_t *a) {

It seems that I reached a limit with CUDA....
I had similar problem with the last release...
And no warning at all !

Very strange, look at the time:  5.00779e+06y to get the 50% ...

Yes 11111 is quite difficult (leading 0).
May be there is also a bug with this particular case. I'll check that.

I restored the old group size.
Could try to update your git repo
And try again.
Many thank for your help.

I confirm that there is a problem with difficulty calculation when searching prefix like 1111something...

I confirm that there is a problem with difficulty calculation when searching prefix like 1111something...

Case 11111.. should be simple:

difficulty = 256^(# of 1 - 1)

Example:
1 --> difficulty 1
11 --> difficulty = 256^1
111 --> difficulty = 256^2



Same error for GPU. Now it's a little slower too.

Code:

I confirm that there is a problem with difficulty calculation when searching prefix like 1111something...

For this prefix vanitygen

256**5 = 1099511627776

[Jean_Luc]

The 1111 is not a problem difficult to solve.
But the other concerning the GPU, f...ing hell !

And all work fine on my 8 years old quadro 600 !

[Jean_Luc]

Good news.
But restoring the group size, and get back in my linux git repo the problem appears.
I will try to debug this.

[Jean_Luc]

I found out an illegal memory access.
I committed a fix on git source.
Thanks to test if it is better or not...

The error remains.

EDIT:
to be precise, now it seems that the results are correct (I made 10 tries) but vanitysearch -check produces the same error: maybe there is something wrong with -check function?

There is something wrong somewhere but where...

vanitygen -check works with a old version, this is the only compile error I got:

vanitygen -check deosn't works with the current version, this is the  compile error I got:

As you can see, in the last there is a different error:  Function properties for _Z10CheckPointPjiiPtjS_S_
