Functions
void	create_lps ()
	Calls ckNew to create the LP chare array (only if we are rank 0), and then starts the charm scheduler on every rank.
void	init_lps ()
	Calls init on the array of LP chares (only if we are rank 0), and then starts the charm scheduler on every rank.
LB Helper Functions
Functions for converting timestamps to weights based on the selected metric. Conversions can be inverted to switch what is considered heavy vs light.
double	tsPercent (Time ts)
double	tsAbs (Time ts)
double	timeToWeight (Time ts)

Variables
CProxy_LPChare	lps
	A readonly declaration for a global lp proxy. More...

Function Documentation

timeToWeight()

double timeToWeight

(

Time

ts

)

Parameters

ts	timestamp to convert to a weight

Returns

the result of tsAbs or tsPercent based on metric configuration

tsAbs()

double tsAbs

(

Time

ts

)

Parameters

ts	timestamp to convert to a weight

Returns

the timestamp bounded by end time, and inverted if required

tsPercent()

double tsPercent

(

Time

ts

)

Parameters

ts	timestamp to convert to a weight

Returns

how close the timestamp is to the simulation end time, as a percent

Variable Documentation

isLpSet

int isLpSet = 0

A flag determining whether the lps global proxy is valid.

It is needed due to the fact that the array isn't created in a mainchare, so the readonly value is not automatically propogated.

lps

CProxy_LPChare lps

A readonly declaration for a global lp proxy.
