Primarily a bug-fix release on top of 2021.03.01. For a full
description, see the README.ReleaseNotes file.

Improvements for hpcviewer

- Improve the performance of hot-path operation by not re-revealing the tree path.
- Default window size is 1400x1000 or the screen size
- Trace view: Move depth field into a separate pane so users can change the depth easily 
  even when call stack view is not visible.
- Reduce memory consumption.
- Use Java XML parser to slightly improve XML parsing performance and avoid using 
  the old Apache xerces. 
- Code clean-up, remove dead code and remove unused variables
- Issue 77: Add support for different color mapping policy in the trace view. 
  Default: procedure-name color instead of random color.
- Warn users when filtering is enabled 
- Default is to build with Eclipse 4.19 (2021.03) except for Linux 
  ppc64le (built with Eclipse 4.16). Some fixes include improved dark color theme.

Bug fixes

hpcrun
CPU issues
- avoid deadlock by not sampling an openmp thread before it finishes
setting up TLS
- avoid having the UCX communication library used by MPI terminate
a program when an unwind fails rather than just dropping a
sample
- fix initialization of control knobs when a process forks but
does not exec
- add a timeout to interrupt a hung cuptiActivityFlushAll and so a program
can terminate and write out all performance data already collected.
Intel GPUs
- always dump Intel GPU binaries so we can extract kernel names
even if not using GTPin binary instrumentation
NVIDIA GPUs
- avoid introducing kernel serialization while using coarse-grain
measurement by monitoring CUPTI_ACTIVITY_KIND_CONCURRENT_KERNEL rather
than CUPTI_ACTIVITY_KIND_KERNEL

hpcstruct
- correct reconstruction of loop nests for Intel GPU binaries

hpcviewer
- Fix issue #80 and #81 (null pointer exception for empty databases)
- Fix issue #79 (CCT filter on the trace view, preserve tree expansion)
- Fix issue #73 (sort direction is not shown on Linux for the first appearance)
- Fix issue #75 (closing only a window in multiple windows mode)
- Fix issue #74 (no sort direction on Linux/GTK)
- Fix issue #85 (keyboard shortcut to minimize the window)
- Fix filtering CCT nodes for thread views
- Fix hot path to select the child node instead of the parent
- Fix merging GPU databases which contain aggregate and derived metrics
by deep copying the metric descriptors.
- Fix build script to include notarization for mac
- Fix storing recent open database: store the absolute path, not the relative one.
- Fix SWT resource leaks
- Fix flickering issue on Windows when splitting the hpcviewer window.
- Fix trace view’s color map changes to also refresh other panes and windows
