Ibm Compilers - IBM z13s Technical Manual

also available for z/OS V1.13 and z/OS V2.1 with PTFs, can help you identify configuration
errors that can result in data integrity exposures.
z/OS V2.2, and z/OS V2.1 with PTFs support the new LPAR absolute group capping
function.
z/OS V2.2 Communications Server supports the virtualization capability of 10GbE RoCE
Express on IBM z13 and z13s processors. z/OS V2.2 is designed to support the SMC-D
protocol for low-latency, high-bandwidth, cross-LPAR connections for applications.
Exploitation of Crypto Express5S features is provided for z/OS V2.2 and with the
Enhanced Cryptographic Support for z/OS V1.13 - z/OS V2.1 web deliverable.
z/OS V2.2 XL C/C++ supports z13 and z13s processors with ARCH(11) andTUNE(11)
parameters that are designed to take advantage of the new instructions.
XL C/C++ support for SIMD instructions with the vector programming language
extensions, and the IBM MASS and ATLAS libraries. This function is also available for
z/OS V2.1 XL C/C++ with a web deliverable available at:
http://www.ibm.com/systems/z/os/zos/tools/downloads/#webdees
New functions are available for ICSF in a new Cryptographic Support for z/OS V1R13 -
z/OS V2R2 This web deliverable is available for download from:
http://www.ibm.com/systems/z/os/zos/tools/downloads/
More support for the z13 processor family is planned with the ICSF Cryptographic Support
for z/OS V1R13 - z/OS V2R2 web deliverable in PTFs in the first quarter of 2016.
Support for the new TKE 8.1 workstation.

1.8.2 IBM compilers

The following IBM compilers for z Systems can use z13s servers:
Enterprise COBOL for z/OS
Enterprise PL/I for z/OS
XL C/C++ for Linux on z Systems
z/OS XL C/C++
The compilers increase the return on your investment in z Systems hardware by maximizing
application performance by using the compilers' advanced optimization technology for
z/Architecture. Compilers like COBOL and C, C++ and Java all use SIMD. Through their
support of web services, XML, and Java, they allow for the modernization of existing assets
into web-based applications. They support the latest IBM middleware products (CICS, DB2,
and IMS), allowing applications to use their latest capabilities.
To fully use the capabilities of z13s servers, you must compile by using the minimum level of
each compiler as specified in Table 1-2.
