Ideal workloads for Power 755 include high performance computing (HPC) applications such as weather and climate modelling, computational chemistry, physics and petroleum reservoir modelling that require highly intense computations where the workload is aligned with parallel processing methodologies. The Power 755 supports AltiVec™ instruction set and extended VSX SIMD, acceleration, which can execute up to eight single-precision or double-precision floating point operations per clock cycle per core to improve fine-grained parallelism and accelerate data processing.

Using 12X InfiniBand adapters up to 641Power 755 nodes, each with 32 cores, can be clustered together providing up to 2,048 POWER7 cores. The IBM High Performance Computing software stack provides the necessary development tools, libraries, and system management software necessary to manage a Power 755 server cluster running AIX®6.1.
