Linux and POWER - great choices for compilers
Many technical advances continue in the realm of classic compiler choices for Linux and for POWER systems. In the open-source community, the gcc.gnu.org community continues to drive technology improvements into the gcc, g++, and gfortran compilers. GCC 4.8 has recently been announced and is available for use across many industry platforms. With IBM's assistance on POWER systems, the latest GCC compilers can provide outstanding performance on the latest POWER systems, including POWER7, POWER7+, and even early... [More]

How we check a new system - the common standard benchmarks
The common standard benchmarks By: Bill Buros. After we have a new Power7 system installed and configured, we generally will run a set of performance benchmarks on the system to confirm that it's running things as we expect it to. In a performance lab like ours, we have the luxury of access to SPEC.org benchmarks, the latest IBM XL C/C++ and Fortran Compilers, the latest gcc-based Advance Toolchain libraries, and the full suite of performance tools and profilers installed on our systems. On a new system, we will regularly install,... [More]

GCC performance - Closing the Performance Gap with an SPECint_rate_base2006 publish
By: Bill Buros. In the continuing journey of performance improvements with GCC, numerous development and performance teams recently hit an interesting milestone with results taking advantage of GCC compilers. The bottom-line difference between similar publishes of SPECint_rate_base2006 has broken the 10% difference milestone on Base measurements. These results are taking advantage of GCC-4.6.1-ibm-r176948 build. The bottom-line difference is calculated by taking the scores of 12 different programs and doing something called a "... [More]
