>
> Key: UIMA-3664
> URL: https://issues.apache.org/jira/browse/UIMA-3664
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Affects Versions: 1.1.0-Ducc
> Reporter: Jim Challenger
> Assignee: Jim Challenger
> Priority: Minor
> Fix For: 1.1.0-Ducc
>
>
> During share counting on a cluster with a large spread of machine sizes (30G
> up to 256G), and there are a lot of requests for 30G shares, but only a few
> for 45G shares, the current code will make a rounding assumption that tends
> to starve the small, 45G job.
> The code needs to change to round UP, not DOWN, if the math calculating
> qshares has a residual.
