Poc2 with error in "buffer and direct" (Linux )

[zezaocapoeira]

Hello.

( sorry bad english)

In this master branch 130aaa9

Compilation ends well without fail

The kernel directory is paired with the binary.

$ ls
devices.txt gpuPlotGenerator kernel

Here only the poc1 option is working.

The error option poc2.

Poc2 with error in "buffer and direct".

I tested the poc2 option with 20480 (5gb) and the same error occurs

Note.

Could put command line poc1 and poc2

./gpuPlotGenerator generate direct /path/to/files/123456_0_50000_5000_poc1

./gpuPlotGenerator generate direct /path/to/files/123456_0_50000_5000_poc2

Thanks for listening.

Hello

(sorry bad english)

Dmesg has captured this error:

# dmesg | grep -i gpuPlot
gpuPlotGenerato[4810]: segfault at 7f4bcdffefd0 ip 00007f4c0ecf18ec sp 00007f4bf0834b38 error 4 in libc-2.23.so[7f4c0eb92000+1c0000]

Maybe it's some incompatibility with this version of glibc?

Thanks for listening.

having same problem with poc2 causing seg fault and dmesg error

Here is the debug log for the above error, but no idea how to solve it.

Please test with the new 4.2.1 version. I mistested the previous version, but this one is fine on the generation part (at least on my side).
The last attention point is on the scoops final ordering. I followed the guidelines from this website. If your miner systematically reject the shares with the new files I'll have to invert the scoops shifting.

[zezaocapoeira]

Hello.
(sorry bad english)

I tested the build be8f94d .

Compilation ok.

And it's working with poc2.

By the time I finish the procedure I will test in the mining (creepMiner),

Thanks for listening.

[zezaocapoeira]

Excuse me.

Github changed the posting scheme and I got confused when it came to selecting the
correct option.

[bhamon]

I verified a simple generated file and compared it against this plotter: as feared there was an inversion in my scoop swapping code.
It's corrected on the master branch now. Please pull and rebuild.

[zezaocapoeira]

Hello.
(sorry bad english)

@bhamon as requested.

I tested the build ad90dc3 .

Compilation ok.

And it's working with poc2.

By the time I finish the procedure I will test in the mining (creepMiner),

Thanks for listening.

[zezaocapoeira]

Hello.
(sorry bad english)

Completing feedback.

It is working well in creepMiner branch development build 8a41b02.

Thanks for listening
