bin/time vs /proc/*/status memory difference?

[ian-bertolacci]

compare bin/time memory value vs /proc/status. Are the different? By how much?

No, not even close.
For test 100x100x10 for 5 time steps on topology (1,1,1):
bin/time: Maximum resident set size (kbytes): 73908
proc/status: VmPeak: 465160 kB
amps: Maximum memory used on processor 0 : 102 MB

Those are all very different values.

for a test 100x100x10-5 (4,1,1):
bin/time is useless, only gives one process: Maximum resident set size (kbytes): 56848
amps:
Maximum memory used on processor 0 : 34 MB
Maximum memory used on processor 1 : 35 MB
Maximum memory used on processor 2 : 35 MB
Maximum memory used on processor 3 : 34 MB

proc/status
VmPeak: 538340 kB
VmPeak: 538844 kB
VmPeak: 538608 kB
VmPeak: 538404 kB

I dont think this is a KiB vs KB thing, since any conversion from one to the other does not result in anywhere near the same storage values as the other systems.
