How can I share the addresses between processes?
Is there a simple way of doing so?
thanks,
Shirley.

Hi,
Yo
• The multi-process feature requires that the exact same hugepage memory
mappings be present in all applications. The Linux security feature -
Address-Space
Layout Randomization (ASLR) can interfere with this mapping, so it may be
necessary to disable this feature in order to reliably run multi-process
applications.

Hi,
You can refer section 20.3 [Multi-Process Limitations] in DPDK Programmer's
Guide.
It says,
• The multi-process feature requires that the exact same hugepage memory
mappings be present in all applications. The Linux security feature -
Address-Space
Layout Randomization (ASLR) can interfere with this mapping, so it may be
necessary to disable this feature in order to reliably run multi-process
applications.
Thanks
Venkat
