    MemtestG80 - ðàìòåñò çà NVIDIA CUDA-enabled GPUs

    MemtestG80 is a software-based tester to test for "soft errors" in GPU memory or logic for NVIDIA CUDA-enabled GPUs. It uses a variety of proven test patterns (some custom and some based on Memtest86) to verify the correct operation of GPU memory and logic. It is a useful tool to ensure that given GPUs do not produce "silent errors" which may corrupt the results of a computation without triggering an overt error.

    Test iteration 1 (GPU 0, 446 MiB): 0 errors so far
    Moving Inversions (ones and zeros): 0 errors (47 ms)
    Memtest86 Walking 8-bit: 0 errors (375 ms)
    True Walking zeros (8-bit): 0 errors (188 ms)
    True Walking ones (8-bit): 0 errors (187 ms)
    Moving Inversions (random): 0 errors (47 ms)
    Memtest86 Walking zeros (32-bit): 0 errors (750 ms)
    Memtest86 Walking ones (32-bit): 0 errors (750 ms)
    Random blocks: 0 errors (328 ms)
    Memtest86 Modulo-20: 0 errors (3438 ms)
    Logic (one iteration): 0 errors (46 ms)
    Logic (4 iterations): 0 errors (110 ms)
    Logic (shared memory, one iteration): 0 errors (62 ms)
    Logic (shared-memory, 4 iterations): 0 errors (157 ms)

    Final error count after 1 iterations over 446 MiB of GPU memory: 0 errors
