# dis\_memory\_usage(7rheolef)

memory used in distributed environment (rheolef-7.2)

## NAME

dis\_memory\_usage - memory used in distributed environment (rheolef-7.2)

## SYNOPSIS

```
size_t seq_memory_usage();
size_t dis_memory_usage();

size_t memory_size();
```

## DESCRIPTION

`seq_memory_usage`

 Returns the current resident set size (physical memory use) measured in bytes, or zero if the value cannot be determined on this OS.

`dis_memory_usage`

 Returns the accumulated memory usage for all processed linked together via the default communicator.

`seq_peak_memory_usage`

 Returns the peak (maximum so far) resident set size (physical memory use) measured in bytes, or zero if the value cannot be determined on this OS.

`dis_peak_memory_usage`

 Returns the accumulated peak memory usage for all processed linked together via the default communicator.

`memory_size`

 Returns the size of physical memory (RAM) in bytes associated to the given process.
