Now i try BitCracker on different system.

Built on Fri_Nov__3_21:07:56_CDT_2017
Cuda compilation tools, release 9.1, V9.1.85

I changed Makefiles to:

Makefile file "src-CUDA"

bitcracker_cuda:
	nvcc -gencode arch=compute_52,code=sm_52 -Xptxas -v -o bitcracker_cuda main.cu cuda_attack.cu utils.cu w_blocks.cu

clean:
	rm -rf *.o
	rm -rf ../build/bitcracker_cuda

Makefile file "src_OpenCL"

#!/bin/bash

FLAGS=-Wextra
NVIDIA_INCLUDE=-I/usr/local/cuda/include -L/usr/local/cuda/lib64
COMMON_INCLUDE=-I/usr/include -L/usr/lib64 -L/usr/lib
MAKE_INCLUDE=$(COMMON_INCLUDE) $(NVIDIA_INCLUDE) -cl-std=CL1.2 -O3

	gcc -I/usr/include -L/usr/lib64 -L/usr/lib -I/usr/local/cuda-9.2/include -L/usr/local/cuda-9.2/lib64 -Wextra -o bitcracker_opencl main.c opencl_attack.c utils.c w_blocks.c -lOpenCL
#	clang -framework OpenCL -o bitcracker_opencl main.c opencl_attack.c utils.c w_blocks.c


clean:
	rm -rf *.o

Then I build Bitcracker and run the tests.
./run_tests.sh

That's weird, you have a Maxwell GPU (and correctly compiled the code with cc5.2).
I tried BitCracker on several GPUs and systems and it never gave me such type of error.
Can you try again removing the kernel execution timeout? Usually it happens when using your GPU concurrently with a graphical application (that could be, for example, you desktop manager). Are you under Linux or Windows?

commented

I use Ubuntu 18.04.1 LTS.
I try to use Bitcracker on TTY mode (CTRL+ALT+F3) because normal desktop mode becomes frozen when i run Bitcracker attack. (I can move mouse cursor, but all view is stuck).
You mean "Can you try again removing the kernel execution timeout?" I do it like here -
https://stackoverflow.com/questions/15833261/how-to-disable-or-change-the-timeout-limit-for-the-gpu-under-linux ?

That's weird, this is the first time this kind of issue arises. Add the -G option in the src_CUDAMakefile , rebuild and then try this cuda-memcheck ./build/bitcracker_cuda -f ./test_hash/imgWin8_user_password.txt -d ./Dictionary/user_passwords.txt -t 1 -b 1 -g 0 -u

I was waiting about 5 minutes, but nothing....
I tried different position of -G option:
nvcc -gencode arch=compute_30,code=sm_30 -G -Xptxas -v -o bitcracker_cuda main.cu cuda_attack.cu utils.cu w_blocks.cu
nvcc -gencode arch=compute_30,code=sm_30 -Xptxas -v -o bitcracker_cuda main.cu cuda_attack.cu utils.cu w_blocks.cu -G

result is same, terminal and all view stuck...
I tried rebuild without -G option and run cuda-memcheck:

It should not get stuck with the -G option... it should only take more time to execute! Please redo these tests with the GPU GeForce GTX 970 because GPU GeForce GTX 760 is too old

commented

I redo tests with Geforce GTX 970 in GUI mode. And I was waiting about an hour, but nothing... stuck on "Attack". Then I tried on TTY mode, result was the same... (In TTY mode I can press Ctrl + C and stop process, in GUI I can only reboot PC).

Maybe problem in OS, Driver, Cuda version?
Maybe you can recommend OS, Nvidia driver and Cuda Tool-Kit version ? I can try to install and redo tests ?

commented

Finally the Bitcracker started to work! Found tests passwords.
I install Kali Linux 2018.3, nvidia driver 390.87 and Cuda-toolkit 9.1.85. (GPU - nvidia Gefroce GTX 760)
but I still do not understand why Bitcracker did not work on Ubuntu 18.04.1

commented

Great to hear you were able to run bitcracker. Thanks for the suggestion, I’ll double check if there is any issue related to Ubuntu 18
