Assessment of measurable points

• Dependency of memory consumption on input resolution from July 7 - July 25, 2014

Metric	Description	Metric baseline	Metric goal	resolution 64 points	128 points	256 points	512 points	1024 points
maximum peak memory used	Maximum of the peak memory used in processing, measured in megabytes.	-	-	129.180	129.727	132.007	212.263	1528.524
max object size handled in bytes	Maximum size of PFM file, measured in megabytes.	-	-	33.82	33.82	33.82	33.82	33.82
min object size handled in bytes	Minimum size of input file in megabytes.	-	-	0.28	0.28	0.28	0.28	0.28

Technical details

• Values of "maximum peak memory used" metric were extracted from /proc/self/status file, concretely the field "RSS" was used. The resident set size is the ammount of a process's memory that is actually held in RAM.
