research relevant to the design and application of high performance scientific computers. We test our ideas by designing, building, and using real systems. The systems we build are research prototypes; they are not intended to become products. There two other research laboratories located in Palo Alto, the Network Systems

Abstract. This paper presents a model for instruction-level distributed computing that allows the implementation of scalable chip multiprocessors. Based on explicit microthreading it serves as a replacement for outof-order instruction issue; it defines the model and explores implementations issues

Abstract—This paper is a review of the developments in Instruction level parallelism. It takes into account all the changes made in speeding up the execution. The various drawbacks and dependencies due to pipelining are discussed and various solutions to overcome them are also incorporated. It goes

. Reconfigurable coprocessors can exploit large degrees of instruction-level parallelism (ILP). In compiling sequential code for reconfigurable coprocessors, we have found it convenient to borrow techniques previously developed for exploiting ILP for very long instruction word (VLIW) processors

instruction-level parallelism. A parameterizable code reorganization and simulation system was developed and used to measure instruction-level parallelism for a series of benchmarks. Results of these simulations in the presence of various compiler optimizations are presented. The average degree

Instruction-level Parallelism CILP) is a family of processor and compiler design techniques that speed up execution by causing individual machine operations to execute in parallel. Although ILP has appeared in the highest performance uniprocessors for the past 30 years, the 1980s saw it become a

The given C program (matrix.c) computes the product of of two matrices, and prints the result. Write a vectorized version of the program, with an aim of maximizing performance with minimal source code changes into matrix-vectorized.c. Use gcc’s vector builtins [1] for Intel’s Streaming SIMD Extensions 3 [2],to write vectorized code, for a x86-64 processor. What to submit? • matrix-vectorized.c, that generates the same output, as matrix.c. matrixvectorized.c should ideally run faster than matrix.c • Report the speedup (measured using time command) and the configuration of the machine on which you ran the code (compiler version – the output of gcc-v and processor info – the output of cat /proc/cpuinfo) Please do not change the compiler flags in the given Makefile

Our goal is to dramatically increase the performance of uniprocessors through the exploitation of instruction level parallelism, i.e. that parallelism which exists amongst the machine instructions of a program. Speculative execution may help a lot, but, it is argued, both branch prediction
