For Tru64 UNIX
This installation guide describes how to install DCPI on Tru64
- Get the release and pcount kits
Copy the DCPI release from the
DCPI download page. Uncompress and untar:
zcat DCPI-<ver>.tar.Z | tar xf -
This will create a directory DCPI-<ver>.
- Install DCPI daemon, utilities, and dynamically loadable
By default, the DCPI-<ver>/INSTALL script may copy the
DCPI loader to /sbin, make links to the utilities and man pages
from /usr/bin and /usr/man, and install the
pcount driver in /var/subsys. Edit the script to suit
local preference, then run it from the directory DCPI-<ver>.
- Collect and analyze data
Make a directory to store the profile database and then start
dcpid to collect profile data.
- Subscribe to our mailing list
Send mail to to be added to our mailing list; this will ensure
that you receive notices about new releases, bug fixes, and
- Read the release
- dcpisource requires perl (Perl4 or Perl5),
which is available from the
Perl home page.
- DCPI cannot be run at the same time as other tools that use
the built-in Alpha hardware performance counters (Iprobe,
kprofile, uprofile, etc.). Anything that uses the pfm
or ipr device drivers will also conflict with DCPI in
its use of the performance counters.
For Windows NT on Alpha
Installation instructions for the Windows NT version can be found in
the Windows NT kit.
