Hello,
I added more details in the check function.
I also enabled the #define FULLCHECK (GPUEngine.cu:1163) which will perform individual test on hash function and ModularMult.
Topic: VanitySearch (Yet another address prefix finder) - page 56. (Read 32072 times)
771 lines of "Expected item not found"
This time all wrong.
Tomorrow, I will add more details in the check function in order to try to understand what is going wrong.
As on my 2 config all is going fine, it is very difficult to debug.

What you can try is to remove the endomorphism for checking.
Comment the following code in GPUEngine.cu around line 1843 (in the Check() function)

An idea would also to noline the _ModInvGrouped (Line 594 GPUEngine.cu)
The errors remain.
OK. That means that 1545 - 549 are ok.
An idea would also to noline the _ModInvGrouped (Line 594 GPUEngine.cu)
I committed GPUEngine.cu (I just removed unused functions) so the line number may be incorrect.

At the end of the list you have the number of items found by the CPU if this number is equal to 549, that means that all are wrong.
At the beginning there are 1534 items:

At the end of the list you have the number of items found by the CPU if this number is equal to 549, that means that all are wrong.
Output of current version (vanitygensearch -check):
The list of item not found has 549 elements. Does it mean that 549 over 1563 are wrong?
there are still errors:

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?

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

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

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 !

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.
