GPU Acceleration - Unexpected output on stdout

Hi! I compiled a function for GPU execution, and it seems to work, at least the outputs are correct. During the execution, I get many outputs on stdout, that look like the following:

Chunk : 0x7f328000e630, 0x7f328000e630, 0, [1, 2049], [2049, 1]
Chunk : 0x7f30cc00e900, 0x7f30cc00e900, 0, [1, 2049], [2049, 1]
Chunk : 0x7f312c00e630, 0x7f312c00e630, 0, [1, 2049], [2049, 1]
...

What does that mean? Can I deactivate this output? Thank you! :slight_smile:

Hey @hallojs,

Thanks for reporting that, it is a debug log that should not be here… it pop from the GPU dataflow runtime here concrete/compilers/concrete-compiler/compiler/lib/Runtime/GPUDFG.cpp at a793fcc099c78d321d6c98139ccee3608fc5a0d8 · zama-ai/concrete · GitHub. Sadly there are nothing to do to desactivate it.
