HP Caliper Linux Release Notes

• The --overflow-block option has been added to specify whether the target
application should be blocked when the PMU sampling buffer is full. The default
is "TRUE" (i.e., the target application will be blocked until HP Caliper has completed
processing all the samples in the buffer). This option is valid only for PMU based
per-process measurements on Linux.
• There are several new options for programming the PMU for advanced
measurements. Refer to the manpage descriptions of --omr, --dbrp, and --ibrp.
Enhancements to the GUI
• Support for IPV6 has been added for HP Caliper GUI communication with the HP
Caliper Server.
• You can now login to remote systems from the GUI using the ssh command. This
is now the default login method.
Using the ssh command has the advantage that your own SSH settings are in
effect when you use the GUI. For example, if you don't want to enter a passphrase
or password from the Caliper GUI, you could do this:
$ ssh-agent /bin/sh
$ ssh-add
[enter your passphrase]
$ Caliper
or
$ ssh-agent
SSH_AUTH_SOCK=/tmp/ssh-2tVlwIXMua/agent.4624; export SSH_AUTH_SOCK;
SSH_AGENT_PID=5948; export SSH_AGENT_PID;
$ SSH_AUTH_SOCK=/tmp/ssh-2tVlwIXMua/agent.4624; export SSH_AUTH_SOCK;
$ ssh-add
[enter your passphrase]
$ Caliper
On Windows, the Caliper GUI has been tested with cygwin's version of Open SSH
(typically installed at C:\cygwin\bin\ssh). Note that the Caliper GUI has not
been tested with the Windows SSH implementation, PuTTY. If your client system
does not have an ssh command, the Login dialog still provides you with the option
of connecting using an SSH libarary that is built in to the GUI. However, if you
use the built-in SSH feature, any passphrase you enter will only be valid for the
duration of your GUI session.
• There is a new source view in the Caliper GUI. Double click on a source line in the
disassembly viewer and the Source view will open the source file and scroll to the
selected source line.
• There are new GUI disassembly enhancements, including: double-click on a branch
to see its target in split window, sort by metric in top window yet maintain address
order in bottom window, register highlighting (via "find" in pop-up menu), and
sort on metric while maintaining issue groups.
• The system usage measurement can now be made and viewed in the GUI.
