" It should be noted that PathScale's bread-and-butter x86 compiler business will continue on. Developed at a time when compilers for Opteron-based HPC clusters were scarce, the PathScale x86 products filled a void in that rapidly expanding market. The C/C++ compilers are tightly integrated with the GNU tool chain, allowing users to build applications that mix and match GNU compiler generated objects with PathScale generated ones.
PathScale also supports Fortran 95, which was derived from an SGI-based open source version. Current customers include big government labs and academic institutions. Although SiCortex isn't planning to develop its own x86-based systems, the company has no intention of alienating HPC customers or losing revenue by abandoning the x86 compiler product line."
