HP Caliper Linux Release Notes

6 Changes in Previous Releases
This section describes changes for the two releases prior to this one.
Changes for Version 5.1
New Options and Enhancements
The HP Caliper 5.1 release has the following improvements:
• The cstack report has been enhanced to report inter-process blocking primitives
(semaphores, message queues, sockets, pipes, regular file descriptors, and so on.).
This process-level-blocking primitive information is provided in addition to the
previously reported primitives (mutexes, rwlocks, condition variables, and so on).
• A new overview measurement provides flat profile, data cache, and call stack
profile information in a single run.
• The collection speed of scgprof (sampled call graph) is improved.
• Improvements are made to the storage of performance data during collection.
Deletions
• The HTML reporting option is deleted. If HP Caliper is invoked using the --html
option, the following message is output:
HP Caliper: usage error:
--html option is no longer supported
Use the -o option for text reports or
Use the GUI to view the database.
Changes for Version 5.0
Enhancements to the GUI
• The HP Caliper GUI for x86 Linux systems now has the option of connecting to a
local, x86–based HP Caliper server (in addition to the capability of connecting to
a remote Itanium-based server). This is useful for viewing performance data
without the need for access to a remote server. Note that the Collect view is disabled
when the GUI connects to the x86–based HP Caliper server as it has no perfomance
measurement capabilities.
The x86–based server is packaged with the x86–based GUI (available from
<install_dir>/gui_clients/caliper-clients.tar.gz). To connect to
the local server, select Locall Connect ... from the main tool bar. The resulting
dialog will be seeded with the path to the local server. Click OK to connect.
