Arm Performance Reports generally requires no configuration before use.
When Arm Performance Reports needs to access another machine as part of starting one of MPICH 1-3, Intel MPI, and SGI MPT, it attempts to use the secure shell, ssh, by default.
However, this may not always be appropriate, ssh may be disabled or be running on a different port to the normal port 22. In this case, you can create a file called remote-exec which is placed in your ~/.allinea directory and Arm Performance Reports will use this instead.
Arm Performance Reports checks for the script at ~/.allinea/remote-_exec, and it will be executed as follows:
The script should start APPNAME on HOSTNAME with the arguments ARG1 ARG2 without further input (no password prompts). Standard output from APPNAME will appear on the standard output of remote-exec.
SSH based remote-exec
A remote-exec script using ssh running on a non-standard port could look as follows:
In order for this to work without prompting for a password, you should generate a public and private SSH key, and ensure that the public key has been added to the ~/.ssh/authorized_keys file on machines you wish to use.
See the ssh-keygen manual page for more information.
Once you have set up your remote-exec script, it is recommended that you test it from the command line. For example:
This returns the output of uname -n on TESTHOST, without prompting for a password.
If you are having trouble setting up remote-exec, please contact Arm support at Arm support for assistance.
The functionality described above is also provided by the Windows remote client. There are two differences:
- The script is named remote-exec.cmd rather than remote-exec.
- The default implementation uses the plink.exe executable supplied with Arm Performance Reports.
