Read Job.tt_smi_version With Fallback

by ADMIN 38 views

Introduction

In the current implementation, we rely on a regex search of the job log output to extract the tt_smi_version information. However, this approach has limitations, especially when dealing with older versions of tt-smi. In this article, we will explore an alternative approach that involves running tt-smi-metal --version, dumping the output to a JSON file, and then reading the JSON file in the data pipeline flow. We will also discuss how to fallback to the --version information in the log output if the JSON file is not found.

The Current Implementation

The current implementation relies on a regex search of the job log output to extract the tt_smi_version information. This approach is simple and straightforward, but it has limitations. For example, if the tt_smi-metal -s command does not print the tt_smi_version information in the host_sw_vers section, the regex search will fail.

The Proposed Solution

The proposed solution involves running the following commands in the reset.sh script:

  1. tt-smi-metal --version
  2. tt-smi-metal -s to dump the output to a JSON file (tt_smi_output.json)
  3. Upload the tt_smi_output.json file as an artifact
  4. Read the tt_smi_output.json file in the data pipeline flow and fallback to the --version information in the log output if not found

Step 1: Run tt-smi-metal --version

The first step is to run the tt-smi-metal --version command to get the version information. This command will output the version number in the format tt-smi-metal version X.X.X.

Step 2: Dump tt-smi-metal -s output to a JSON file

The second step is to run the tt-smi-metal -s command to dump the output to a JSON file (tt_smi_output.json). This command will output the system information in a JSON format, which can be easily parsed and read in the data pipeline flow.

Step 3: Upload the tt_smi_output.json file as an artifact

The third step is to upload the tt_smi_output.json file as an artifact. This will make the file available for reading in the data pipeline flow.

Step 4: Read the tt_smi_output.json file in the data pipeline flow

The fourth step is to read the tt_smi_output.json file in the data pipeline flow. If the file is found, the data pipeline flow can read the tt_smi_version information from the JSON file. If the file is not found, the data pipeline flow can fallback to the --version information in the log output.

Benefits of the Proposed Solution

The proposed solution has several benefits over the current implementation. For example:

  • It provides a more reliable way to extract the tt_smi_version information, especially when dealing with older versions of tt-smi.
  • It allows for easier parsing and reading of the tt_smi_version information in the data pipeline flow.
  • It provides a fallback mechanism in case the tt_smi_output.json file is not found.

Implementation Details

The implementation details of the proposed solution are as follows:

  • The reset.sh script will run the tt-smi-metal --version command to get the version information.
  • The reset.sh script will run the tt-smi-metal -s command to dump the output to a JSON file (tt_smi_output.json).
  • The reset.sh script will upload the tt_smi_output.json file as an artifact.
  • The data pipeline flow will read the tt_smi_output.json file and extract the tt_smi_version information.
  • If the tt_smi_output.json file is not found, the data pipeline flow will fallback to the --version information in the log output.

Conclusion

In conclusion, the proposed solution provides a more reliable and efficient way to extract the tt_smi_version information. By running tt-smi-metal --version, dumping the output to a JSON file, and reading the JSON file in the data pipeline flow, we can provide a fallback mechanism in case the JSON file is not found. The implementation details of the proposed solution are as follows:

  • The reset.sh script will run the tt-smi-metal --version command to get the version information.
  • The reset.sh script will run the tt-smi-metal -s command to dump the output to a JSON file (tt_smi_output.json).
  • The reset.sh script will upload the tt_smi_output.json file as an artifact.
  • The data pipeline flow will read the tt_smi_output.json file and extract the tt_smi_version information.
  • If the tt_smi_output.json file is not found, the data pipeline flow will fallback to the --version information in the log output.

Future Work

Future work includes:

  • Implementing the proposed solution in the reset.sh script.
  • Testing the proposed solution to ensure that it works as expected.
  • Refining the implementation details of the proposed solution as needed.

Appendix

The following is an example of the reset.sh script that implements the proposed solution:

#!/bin/bash

# Run tt-smi-metal --version to get the version information
tt_smi_version=$(tt-smi-metal --version)

# Run tt-smi-metal -s to dump the output to a JSON file
tt_smi_output=$(tt-smi-metal -s)

# Upload the tt_smi_output.json file as an artifact
aws s3 cp tt_smi_output.json s3://my-bucket/tt_smi_output.json

# Read the tt_smi_output.json file in the data pipeline flow
if [ -f tt_smi_output.json ]; then
  tt_smi_version=$(jq -r '.tt_smi_version' tt_smi_output.json)
else
  tt_smi_version=$tt_smi_version
fi

# Print the tt_smi_version information
echo "tt_smi_version: $tt_smi_version"

Introduction

In our previous article, we discussed a proposed solution for reading the tt_smi_version information with a fallback mechanism. In this article, we will answer some frequently asked questions (FAQs) about the proposed solution.

Q: Why do we need a fallback mechanism?

A: The current implementation relies on a regex search of the job log output to extract the tt_smi_version information. However, this approach has limitations, especially when dealing with older versions of tt-smi. The fallback mechanism provides a reliable way to extract the tt_smi_version information in case the JSON file is not found.

Q: How does the fallback mechanism work?

A: The fallback mechanism works by reading the --version information from the log output if the JSON file is not found. This ensures that the data pipeline flow can still extract the tt_smi_version information even if the JSON file is not available.

Q: What are the benefits of the proposed solution?

A: The proposed solution has several benefits, including:

  • A more reliable way to extract the tt_smi_version information
  • Easier parsing and reading of the tt_smi_version information in the data pipeline flow
  • A fallback mechanism in case the JSON file is not found
