PathScale
PathScale is designing and engineering high-performance 64-bit server computer systems optimized for use in Linux clusters. PathScale has a new, innovative approach to building servers. These servers are designed for larger cluster users who are concerned about the overall economics of server computing. They are focused on the creation of a new categories of servers through the convergence of processor, networking, and storage technology. The PathScale Compiler Suite represents the highest-performance 64-bit compiler for the AMD Opteron processor. This advanced compiler suite takes advantage of the AMD Opteron high performance 64-bit features and its remarkable price/performance leadership. The PathScale compilers provide 100% binary compatibility, with the ability to mix and match the linking of GNU and PathScale compiled libaries and objects. The front ends are source compatible with the GNU compiler suite for C/C++ . The FORTRAN 90 compiler provides support for the most common Cray/SGI extensions.
