The following steps describe how to run an ALF application.
Note: You need to ensure that the dynamic libraries libalf_hybrid and libdacs_hybrid are
accessible. You can set this through LD_LIBRARY_PATH. For
example:
export LD_LIBRARY_PATH=/opt/cell/sdk/
To run an application, do the following:
Build the ALF for Hybrid-x86 application, both
the host application as an executable, my_appl, and the accelerator
computational kernel as a PPE shared library, my_appl.so.
Copy the PPE shared library with the embedded
SPE binaries from the host where it was built to a selected directory on the
Cell BE where it is to be executed. For example:
scp my_appl.so <CBE> :/tmp/my_directory
Set the environment variable ALF_LIBRARY_PATH to
the above selected directory on the Cell BE. For example:
export ALF_LIBRARY_PATH=/tmp/my_directory
Set the processor affinity on the Hybrid-x86 host.
Refer to the DaCS Programmer’s Guide and API Reference, section
"Affinity requirements for host applications" for more information about how
to do this. For example:
taskset –p 0x00000001 $$
Run the x86_64 host application in the host environment.
For example: ./my_appl
