San Jose, Calif. - April 5, 2004 - PathScale, Inc., developer of innovative 
software and hardware solutions to accelerate the performance and efficiency 
of Linux clusters, is now accepting orders for its industry-leading suite of 
high-performance Linux compilers for AMD Opteron(TM) and Athlon64(TM) 
processor-based systems. Initial orders for the PathScale EKO Compiler Suite 
have already been received from high performance computing sites in North 
America, Europe and the Pacific Rim. In addition, the company has enrolled a 
number of resellers and is continuing to sign additional new partners. 

The PathScale compilers can now be ordered via the PathScale Web site at 
www.pathscale.com or from any PathScale Reseller. Compiler ordering 
information and a teaming agreement with IBM regarding its Departmental 
Supercomputing Solutions are being announced this week at the ClusterWorld 
Conference and Expo in San Jose. 

PathScale C, C++ and Fortran 77/90/95 compilers leverage the AMD Opteron 
processor's high-performance 64-bit functionality and industry-leading 
price/performance. Results on real application code and industry standard 
benchmarks show that the PathScale Compiler Suite offers the highest 
performance 64-bit compilers for AMD Opteron processor-based Linux servers 
by a margin of up to 40 percent. 

Annual subscription fees for the complete PathScale Compiler Suite start at 
$1,495 per license and include all appropriate software, updates, upgrades 
and support services for the entire year. License quantities and volume 
discounts are based on the number of developers using the compiler and the 
total number of compile servers being deployed. 

PathScale also announced the appointment of Art Goldberg as its Chief 
Operating Officer. Goldberg has more than 35 years of experience in the high 
performance computing industry, including 24 years with IBM in various sales
