Table format:

• Time: physical time
• Step: number of root-level updates
• Virtual_Max: maximum virtual memory consumption in one MPI process
• Virtual_Sum: total virtual memory consumption in all MPI processes
• Resident_Max: maximum resident memory consumption in one MPI process
• Resident_Sum: total resident memory consumption in all MPI processes

Caution: CUDA may consume very large virtual memory. However, it doesn't seem to be a serious problem in most cases.
