Rosetta Job Failed on Node comput16: Executable Not Found

A Rosetta job submitted on April 18, 2023 at 4:20 AM CST failed to run on node 'comput16'. The error message indicates that the executable, located at '/mnt/hpc/software/apps/rosetta.source.release-314/main/source/bin/rosetta_scripts.linuxgccrelease', could not be accessed or executed. This prevented all 32 processes from starting.

Here's a breakdown of the issue:

• Error Message: 'mpirun was unable to launch the specified application as it could not access or execute an executable.'
• Executable Path: '/mnt/hpc/software/apps/rosetta.source.release-314/main/source/bin/rosetta_scripts.linuxgccrelease'
• Affected Node: 'comput16'
• Number of Processes Impacted: 32

To troubleshoot this, verify the following:

1. Executable Exists: Ensure the Rosetta executable file exists at the specified path and is accessible.
2. Permissions: Check the file permissions of the executable. It should have execute permissions for the user running the job.
3. Environment Variables: Confirm that all necessary environment variables, including PATH and LD_LIBRARY_PATH, are correctly set to locate the Rosetta executable and its dependencies.
4. Node Availability: Verify that node 'comput16' is online and accessible.

Addressing these common causes can help resolve the issue and allow your Rosetta job to run successfully.
