3 Important information

  • Your instance of RStudio is executed inside a container and ONLY the files stored in your HOME directory in the ReCaS-Bari GPFS file system will be preserved if faults occur, namely /lustrehome. Any local file content or module installation is lost if the container is stopped or crashes. So, use the GPFS file system for all your important files.

  • Containers could crash at any time also during the execution of the code, partial results CAN NOT be restored and will be lost. To manage this situation, consider storing in your HOME directory in GPFS all partial results.

  • Also consider that you do not have infinite space in the GPFS file system. Use it wisely.
