/AWS1/CL_BTCFAIRSHAREPOLICY

The fair-share scheduling policy details.

CONSTRUCTOR

IMPORTING

Optional arguments:

iv_sharedecayseconds TYPE /AWS1/BTCINTEGER /AWS1/BTCINTEGER

The amount of time (in seconds) to use to calculate a fair-share percentage for each share identifier in use. A value of zero (0) indicates the default minimum time window (600 seconds). The maximum supported value is 604800 (1 week).

The decay allows for more recently run jobs to have more weight than jobs that ran earlier. Consider adjusting this number if you have jobs that (on average) run longer than ten minutes, or a large difference in job count or job run times between share identifiers, and the allocation of resources doesn't meet your needs.

iv_computereservation TYPE /AWS1/BTCINTEGER /AWS1/BTCINTEGER

A value used to reserve some of the available maximum vCPU for share identifiers that aren't already used.

The reserved ratio is (computeReservation/100)^ActiveFairShares where ActiveFairShares is the number of active share identifiers.

For example, a computeReservation value of 50 indicates that Batch reserves 50% of the maximum available vCPU if there's only one share identifier. It reserves 25% if there are two share identifiers. It reserves 12.5% if there are three share identifiers. A computeReservation value of 25 indicates that Batch should reserve 25% of the maximum available vCPU if there's only one share identifier, 6.25% if there are two fair share identifiers, and 1.56% if there are three share identifiers.

The minimum value is 0 and the maximum value is 99.

it_sharedistribution TYPE /AWS1/CL_BTCSHAREATTRIBUTES=>TT_SHAREATTRIBUTESLIST TT_SHAREATTRIBUTESLIST

An array of SharedIdentifier objects that contain the weights for the share identifiers for the fair-share policy. Share identifiers that aren't included have a default weight of 1.0.

computeReservation

A value used to reserve some of the available maximum vCPU for share identifiers that aren't already used.

The reserved ratio is (computeReservation/100)^ActiveFairShares where ActiveFairShares is the number of active share identifiers.
