Summary: DUCC RM - rounding error allocation shares
Key: UIMA-3664
URL: https://issues.apache.org/jira/browse/UIMA-3664
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jim Challenger
Assignee: Jim Challenger
Priority: Minor
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.
