TSUBAME3 has a trial execution function that allows you to check program operation without consuming points.
The trial execution function is originally prepared so that users who are worried about using TSUBAME for their own research can check the operation before purchasing points. Please do not use the trial execution function for calculations that lead to a connection.
If you want to perform small calculations for educational purposes in class, consider using the interactive queue.
About the trial execution, please refer to the user manual.
