Infrastructure Released to Promote Widespread EPIC Compiler

Development, Enhance Performance for Future EPIC/IA-64 Systems

Hewlett-Packard Company, the IMPACT compiler group at the University of Illinois at Urbana-Champaign Early years: 1867-1880
The Morrill Act of 1862 granted each state in the United States a portion of land on which to establish a major public state university, one which could teach agriculture, mechanic arts, and military training, "without excluding other scientific

It comprises 13 schools and colleges, maintaining 4 main centers (including the Medical Center) in the city, as well as the  in New York City New York City: see New York, city.

 today released the Trimaran EPIC (Explicitly Parallel Instruction Computing Explicitly Parallel Instruction Computing (EPIC) is a computing paradigm that began to be researched in the early 1980s resulting in a U.S. patent 4,847,755 (Gordon Morrison, et. al).[1] This paradigm is also called Independence architectures. ) compiler research infrastructure to the academic community.

The infrastructure is expected to facilitate instruction and research in EPIC technology and to lower the barrier to entry for research and instruction in this field greatly. It also is expected to help universities participate in development of EPIC compiler technology. IA-64 (Intel(R) Architecture 64-bit), Intel's next-generation microprocessor platform, is based on EPIC technology, co-developed by HP and Intel.

HP Labs has been developing EPIC compilers since 1989 in the company's Compiler and Architecture Research group and as part of the PA-WideWord program. Extensive compiler research has continued at HP Labs and through cooperative efforts with the University of Illinois University of Illinois may refer to:
  • University of Illinois at Urbana-Champaign (flagship campus)
  • University of Illinois at Chicago
  • University of Illinois at Springfield
  • University of Illinois system
It can also refer to:
 and New York University. The research infrastructure produced through these cooperative efforts is available free of charge at http://www.trimaran.org to universities interested in studying EPIC compilers.

The Trimaran team is helping universities overcome financial barriers to establishing EPIC compiler research programs by providing a research infrastructure at no cost. While many universities have infrastructures for superscalar A CPU architecture that allows more than one instruction to be executed in one clock cycle. See pipeline processing.

(architecture) superscalar - A superscalar architecture is a uniprocessor that can execute two or more scalar operations in parallel.
 and multiprocessor research, most are just beginning to study next-generation EPIC technology. HP believes that extensive research will produce significant gains in EPIC compiler technology and help realize the tremendous performance potential of EPIC architectures. HP intends to continue its own compiler research as well.

HP's Compiler and Architecture Research group is headed by B. Ramakrishna Rau, who holds a doctorate in electrical engineering electrical engineering: see engineering.

"Years of EPIC compiler research enable HP to provide this information to the academic community while maintaining a significant edge in designing IA-64-based systems with the highest performance levels," said Bill Russell, HP vice president and general manager of the Enterprise Systems Group. "Continuing our innovation in advanced compiler technology and fostering a strong research infrastructure for the academic community reinforces HP's commitment to driving the broad adoption of IA-64 technology. The expertise and knowledge HP has gained in co-developing EPIC positions the company to deliver systems that realize the full potential of IA-64 technology."

EPIC compilers use access to architectural information and control over processor execution to expose, exploit and orchestrate opportunities for parallelism within an application, thus extracting maximum speed and performance from EPIC/IA-64 systems. HP expects EPIC/IA-64 systems to offer significant advantages over existing computing platforms.
