IBM POWER8 in the press

5 MariaDB Roadshow in Düsseldorf, München und Wien im April 2015

ComputerWorld: To make the chip faster, IBM has turned to a more advanced manufacturing process, increased the clock speed and added more cache memory, but perhaps the biggest change heralded by the Power8 cannot be found in the specifications. After years of restricting Power processors to its servers, IBM is throwing open the gates and will be licensing Power8 to third-party chip and component makers.

The Register: the Power8 is so clearly engineered for midrange and enterprise systems for running applications on a giant shared memory space, backed by lots of cores and threads. Power8 does not belong in a smartphone unless you want one the size of a shoebox that weighs 20 pounds. But it most certainly does belong in a badass server, and Power8 is by far one of the most elegant chips that Big Blue has ever created, based on the initial specs.

PCWorld: With Power8, IBM has more than doubled the sustained memory bandwidth from the Power7 and Power7+, to 230 GB/s, as well as I/O speed, to 48 GB/s. Put another way, Watson’s ability to look up and respond to information has more than doubled as well.

Microprocessor report: Called Power8, the new chip delivers impressive numbers, doubling the performance of its already powerful predecessor, Power7+. Oracle currently leads in server-processor performance, but IBM’s new chip will crush those records. The Power8 specs are mind boggling.

MigraEon scenarios for applicaEons


PorEng Script/interpreted language based ApplicaEons to POWER8

!  All script languages and interpreted languages should be platform-independent once they are compiled for the particular platform.

!  Also compiled code should be platform-independent (e.g., Perl, Python etc.). !  Examples include:

–  Perl –  Python –  PHP –  Ruby –  Lua –  Tcl –  etc.


PorEng JAVA based ApplicaEons to Linux on POWER8

!  Java compiled byte-code is platform-independent and thus portable across different platform if the Java specification has been adhered to, i.e., no APIs/syscalls beyond the specification have been used.

!  For PowerLinux the Java JVM options are: –  IBM JVM –  OpenJDK

!  For Linux/x86 multiple different JVMs are available. !  Differences in behavior between the IBM JVM and the Oracle JVM exist.

!  Additional efforts in migrating Java code typically arise only if Java extensions were used that are not part of the standard Java specification:

–  For instance, security-relevant Java code differs between JVMs of different vendors.


PorEng C/C++ Code to Linux on POWER8 requires a recompile

Other Linux RHEL, SLES, or Ubuntu (not RHEL, SLES, Ubuntu)

RHEL RHEL

SLES SLES

Ubuntu Ubuntu


IBM (C/C++) MigraEon Advisor for Linux on Power

!  The IBM Software Development Kit for PowerLinux includes a Migration Advisor to help in moving Linux applications from x86 systems to Power systems.

!  The advisor uses the Eclipse C/C++ Development Tools code analysis tool. !  The code analysis tool locates potential migration problems within a project,

such as source code that might produce different results when run on Power systems.

!  It contains several checkers that look for code in the project that might produce a different result in Power systems.

!  Warnings are displayed showing the kind of problem found.


PorEng C/C++ 32 bit ApplicaEons to Linux (ligle endian) on POWER8

!  Changing the address space for the application, i.e., converting it from a 32-bit to a 64-bit application

–  Might be required if porting 32-bit application to 64-bit only like distributions (ppc64le) like Ubuntu, SLES12 or RHEL 7.1

!  A 32-bit Linux/Intel application can always be recompiled as a 32-bit Linux/Power application, no need to change anything here!

–  The exception is new OpenPOWER compliant ppcle64 platform

!  Converting a 32-bit application to 64-bit address space can present a challenge depending on the code quality!

!  Please see the redbook “AIX5L Porting Guide“ for details:

AddiEonal informaEon


Summary

!  Source code based on script languages should be no problem / easy to port. !  Recompiling C/C++ source code from Linux/Intel on Linux/Power is pretty

straight forward. !  Portability issues typically arise only with regards to

–  (Endianness Linux x86 is little endian, Power used to be big endian only, most recent Ubuntu, SLES and RHEL versions for PPOWER8 are little endian).

–  using x86-specific •  APIs. •  assembly code. •  compiler built-ins.

!  The Migration Advisor as part of the Linux on Power SDK can assist in identifying possible migration issues.

!  The majority of commonly used open source code is pretty portable across different platforms, more efforts could be expected with custom code that has only been running on one platform (Intel).


IBM Sojware Development Kit for Linux on Power

The IBM SDK for Linux on Power package includes:

!  IBM Advance Toolchain for Linux on Power integration, Versions 7.0-5, 7.1-0, and 8.0-0

!  IBM SDK for Linux on Power, Version 1.6.1 !  Feedback Directed Program Restructuring (FDPR), Version 5.6.2-6c !  Pthread Monitoring tool for Linux on Power (pthread-mon), Version 0.5.10-1 !  IBM SDK Java Technology Edition Version 7.1 !  IBM POWER8 Functional Simulator


IBM Advance Toolchain for PowerLinux

URLs: !  PowerLinux Community wiki !  IBM Advance Toolchain for PowerLinux Documentation !  Improving performance with IBM Advance Toolchain for PowerLinux

Description: !  The IBM Advance Toolchain for PowerLinuxTM provides early and easy access

to libraries and the latest compiler technologies for Linux distributions. !  Over time, these libraries and latest compiler technologies are integrated into

the shipping distributions. !  However, the IBM Advance Toolchain for PowerLinux contains the latest tested

and supported GNU Compiler Collection (GCC) compiler versions, tailored for Power systems, and packaged together with an expanding set of processor-tuned libraries, allowing you to take advantage of the latest technology without waiting..


Linux/x86 to Linux on Power applicaEon migraEon

Linux on Power Migration Advisor checkers: !  x86-specific compiler built-in checker !  x86-specific assembly checker !  Struct with bitfields checker !  Cast with endianness issues checker !  Union with endianness issues checker !  Long double usage checker !  Performance degradation checker !  System call not available for PowerLinux checker !  Linux/x86-specific API checker !  Hardware Transaction Memory checker !  Non-portable Pthreads implementation checker


Endianness – why do I care about it?

!  Linux on Power has chosen to exploit little endian (LE) processor mode based on OpenPOWER partner feedback instead of big endian (BE).

–  Eases the migration of applications from Linux on x86.

–  Enables simple data migration from Linux on x86.

–  Simplifies data sharing (interoperability) with Linux on x86. –  Improves Power I/O offerings with modern I/O adapters and devices, e.g. GPUs.

!  Creation of an LE operating system for Linux on Power means creating a whole new software “platform” (ppc64le) (in addition to BE ppc (32-bit) and BE ppc64 (64-bit)).

!  LE distributions for Linux on Power does NOT mean x86 applications magically run: applications must still be compiled for Power.

!  Power8 CPU can be either big or little endian % mixed endianness (big and little) on same system is possible.
