PROBLEM TO BE SOLVED: To beef up security with respect to execution files without losing convenience of users in calculation processing using cloud computers.SOLUTION: In application execution start processing S50, a cloud computer navigation system is configured to: log in an HPC server as a management server (S52); alleviate an authority with respect to execution files stored in a storage area accessible only by management users and set to be executable only by the management users, and allow ordinary users belonging to the same group as the management users to execute the execution files (S53); and restore the authority with respect to the execution files (S56) after detecting an execution start of a calculation using the execution files in the HPC server (S55).SELECTED DRAWING: Figure 3 |
