Acceleration with the on-chip Integrated Accelerator for zEDC is available to applications that use zlib or gzip in user space and to the kernel zlib.

SUSE Linux Enterprise Server 15 SP5 LPAR mode z/VM guest KVM guest

Acceleration for applications in user space

Applications can use the on-chip accelerator through zlib and gzip. SUSE Linux® Enterprise Server 15 SP5 includes the required versions.

For Linux containers, the image must contain the required versions of zlib and gzip. You can search the zlib and gzip binaries for DFLTCC to verify that you have the required versions, as in the following example:

# grep DFLTCC /usr/lib64/libz.so
Binary file /usr/lib64/libz.so matches
# grep DFLTCC /usr/bin/gzip 
Binary file /usr/bin/gzip matches

Acceleration for Java™ workloads

Support for Java workloads depends on your Java platform implementation.

Java implementations that use the system zlib, for example OpenJDK, support the on-chip accelerator if the system zlib supports it.

The IBM® SDK for Java includes a zlib library, so its support of the on-chip accelerator is independent of the system zlib. As of IBM SDK for Java 8 SR6, the included zlib supports the on-chip accelerator.

Acceleration for the kernel

The kernel zlib can use the on-chip accelerator.
