Hubli-580031 Abstract: aero dynamical problems, [1].Since 1986, six Flosolver MK6 is a Parallel processing system, generations of Flosolver machine have evolved based on distributed memory concept and built namely Flosolver MK-1, MK-2, MK-3, MK-4, MK-5 around Pentium-III processors, which acts as and MK-6. processing elements (PEs). Communication Flosolver MK-6 is the latest of the parallel between processing elements is very important, computer based on 128 Pentium III processors which is done through hardware switch called (which act as processing elements, PEs) in 64 dual Floswitch. Floswitch supports both message processor boards each with 1GB RAM and 80 GB passing as well as message processing. Message HDD. It is essentially a distributed memory system. processing is a unique feature of Floswitch. A group of four Dual processor boards with a Floswitch and an optical module is a natural cluster. In existing MK-6 system, communication 16 such clusters form the system. Processing between PEs is done through the Intel 486-based elements (PEs) communicate through Floswitch (a Floswitch, which operates at 32MHz and has 32- communication switch) using PCI-DPM interface bit wide data path. The data transfer rate and card. Clusters communicate through Optical module. floating point computation of existing switch need to be increased. -

Evolution of Microprocessor Performance
EvolutionEvolution ofof MicroprocessorMicroprocessor PerformancePerformance So far we examined static & dynamic techniques to improve the performance of single-issue (scalar) pipelined CPU designs including: static & dynamic scheduling, static & dynamic branch predication. Even with these improvements, the restriction of issuing a single instruction per cycle still limits the ideal CPI = 1 Multiple Issue (CPI <1) Multi-cycle Pipelined T = I x CPI x C (single issue) Superscalar/VLIW/SMT Original (2002) Intel Predictions 1 GHz ? 15 GHz to ????

Energy Per Instruction Trends in Intel® Microprocessors
Energy per Instruction Trends in Intel® Microprocessors Ed Grochowski, Murali Annavaram Microarchitecture Research Lab, Intel Corporation 2200 Mission College Blvd, Santa Clara, CA 95054 [email protected], [email protected] Abstract where throughput performance is the primary objective. In order to deliver high throughput performance within a Energy per Instruction (EPI) is a measure of the amount fixed power budget, a microprocessor must achieve low of energy expended by a microprocessor for each EPI. instruction that the microprocessor executes. In this It is important to note that MIPS/watt and EPI do not paper, we present an overview of EPI, explain the consider the amount of time (latency) needed to process factors that affect a microprocessor’s EPI, and derive a an instruction from start to finish. Other metrics such as MIPS 2/watt (related to energy•delay) and MIPS 3/watt historical comparison of the trends in EPI over multiple 2 generations of Intel microprocessors. We show that the (related to energy•delay ) assign increasing importance recent Intel® Pentium® M and Intel® Core™ Duo to the time required to process instructions, and are thus microprocessors achieve significantly lower EPI than used in environments in which latency performance is what would be expected from a continuation of historical the primary objective. trends. 2.
