AMD x86 Open64 Compiler Suite 4.2.5

Code generation tool designed for high performance parallel computing workloads
The AMD x86 Open64 Compiler Suite is a high performance, production quality code generation tool designed for high performance parallel computing workloads. The x86 Open64 environment provides the developer the essential choices when building and optimizing C, C++, and Fortran applications targeting 32-bit and 64-bit Linux platforms.

The x86 Open64 compiler system offers a high level of advanced optimizations, multi-threading, and processor support that includes global optimization, vectorization, interprocedural analysis, feedback directed optimizations, loop transformations, and code generation which extracts the optimal performance from each x86 processor core.

The x86 Open64 Compiler Suite simplifies and accelerates development and tuning for x86, AMD64 (AMD® x86-64 Architecture), and Intel64 (Intel® x86-64 Architecture) applications. The x86 Open64 compilers create a strong foundation for building robust, high performance parallel code through MPI, OpenMP®, and auto-parallelization along with highly optimized libraries*.
