Priority: medium
Bug ID: 76290
Assignee: [email protected]
Summary: use OpenMP for image algorithms
Severity: normal
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: Other
Status: UNCONFIRMED
Version: unspecified
Component: Libreoffice
Product: LibreOffice
The image algorithms in vcl/source/gdi/bitmap3.cxx are perfect examples for
algorithms that benefit from parallel execution.
The task is to go through each function identify the parallel sections and
check that the memory access allows parallel execution (no overlapping
read/write in the same memory, no overlapping writes in the same memory, ...)
and use OpenMP to make the code use more cores in modern processors.
This also requires some makefile changes to support compiling files with OpenMP
enabled.
