O padrão de fato parece ser CUDA GPU Memtest . Como c2h5oh mencionou, parece que é baseado em padrões de teste memtest86, então tenho certeza que faz um bom trabalho. Ele é executado com relativa rapidez nas GPUs de ponta que estou testando (30 minutos no Quadro 6000 e 20 minutos no Tesla C2075). Ele é executado dentro do sistema operacional (ao contrário do memtest), portanto, o monitoramento é um pouco diferente. Você provavelmente desejará produzir stdout e stderr em um arquivo para analisar mais tarde. Portanto, considere a possibilidade de executar algo assim, caso você perca sua saída de terminal, você pode procurar o que os testes encontraram:
cuda_memtest 2>cuda_memtest.stderr 1>cuda_memtest.stdout &
tail -f cuda_memtest.stdout &
tail -f cuda_memtest.stderr &
Você também vai querer ter certeza de que ninguém está usando o sistema e / ou cartões. Você pode definir as GPUs para o modo exclusivo usando:
nvidia-smi --compute-mode=EXCLUSIVE_PROCESS
Aqui estão alguns resultados das execuções de amostra do Quadro e do Tesla, caso você esteja interessado em saber quais informações de teste são fornecidas:
