What is a good AMI for GPU-based tensorflow work?

0

Hi, Using the ec2 instance (p3.8xlarge - 4 V100 GPUs) I cannot find an AMI that makes use of these with tensorflow [-gpu].

I've tried:

  • NVIDIA GPU-Optimized AMI - issues, very little installed, but that's ok as it is ubuntu and you can install whatever. But, with tensorflow-gpu installed: print (tf.version) print("Num GPUs Available: ", len(tf.config.list_physical_devices('GPU'))) 2.9.1 Num GPUs Available: 0 Other AMI's see the GPUs, but are unable to utilize them (using nvidia-smi to monitor usage). For this, I've tried:
  • Deep Learning AMI GPU TensorFlow 2.9.1 (Amazon Linux 2) 20220803
  • Deep Learning AMI GPU TensorFlow 2.9.1 (Ubuntu 20.04) 20220803

Has anyone successfully deployed GPUs on a DLAMI? This time last year I was able to use individual GPUs ok (distributed is another thing, but this year none are working).

Thanks,

Hello,

The size of your model should be a factor in selecting an instance. If your model exceeds an instance's available RAM, select a different instance type with enough memory for your application.

Amazon EC2 P3 Instances have up to 8 NVIDIA Tesla V100 GPUs.

Amazon EC2 P4 Instances have up to 8 NVIDIA Tesla A100 GPUs.

Amazon EC2 G3 Instances have up to 4 NVIDIA Tesla M60 GPUs.

Amazon EC2 G4 Instances have up to 4 NVIDIA T4 GPUs.

Amazon EC2 G5 Instances have up to 8 NVIDIA A10G GPUs.

Amazon EC2 G5g Instances have Arm-based AWS Graviton2 processors

Refer this link- https://docs.aws.amazon.com/dlami/latest/devguide/gpu.html for more details on the selection of instances.

Hope this helps, If yes, please click accepted answer.

  • Yes, the size of the model is one thing - mine is pretty large (5 MByte), but the data set can be 1000's of times larger than that. So holding batches in memory of the GPU is critical. Hence I chose p3.8xlarge, which is the smallest I can get away with. But the question wasn't about that, it was what AMI instance to choose. I listed three that were no use and was asking the community what they have found to work well with tensorflow, good utilization of GPUs, and potentially distributed training.
