Mix of IPP5.3 and IPP7.0

Hi.

We use a third party lib that uses IPP 5.3.
So the rpm installs needed IPP libs in /usr/lib (e.g /usr/lib/libippcore.so.5.3)
In the build system, the third party gives us a lcf file to add for the linker (adds -lippcore and -lipps)

Our software also needs IPP.
So I have installed IPP 7.0 in order to build our application using IPP.

If I don't change the /etc/ld.so.conf the binary uses the lib from /usr/lib (so uses IPP 5.3)
By adding correct path in ld.so.conf, I forced the binary to use the libs from /opt/intel/ ... (using IPP 7.0)

Is it risky to use IPP 7.0 with a lib that has been designed to work with IPP 5.3 ?

Do you see any possible issues, thinks to check to make it work ?

Thanks

Chris

Hi Chris,

I have not tried it, but it should work.

There is one article explains how to use multiple versions of IPP, refer to below link

The only potential issues I see are:

- New library may not have all functions that the older library had.
- New library may not support some older CPUs.
- OpenMP implementations may be different and result in conflict and slow performance at best, and inaccuracy or crashing at worst.
