public subroutine tem_trackmem(memfile, iteration)

Write the current memory status into the memfile.

The file will be opened and closed, so this might be slow. Only the root process writes to this file, but the data is gathered from all processes. The output will be prepended by the current date. We will track the VmHWM: from /proc/self/status, MemFree:, Buffers: and Cached: from /proc/meminfo and pgmajfault from /proc/vmstat The min, max and average across all processes will be recorded.

Arguments

character(len=*), intent(in) :: memfile
integer, intent(in) :: iteration
