How is the performance of a computer measured?

Given : Instruction Type 1, 2, and 3 on Machine M             CPI1 = 1 ; CPI2 = 2; CPI3 = 3 Answer with just a number a. What is Average CPI of machine M running a program P that has 31% Type 1 instructions, 29% Type 2 instructions, and the remainder Type 3 instructions? Answer with just a number. [avgCPI] b What is the execution time if  program P has 15000 instructions and machine M has a clock rate of 4 GHz? Give your answer in microseconds, with 3 numbers after the decimal point. Just a number no units. [executiontime] c. What is the speedup if M’s clock rate is improved to 5 GHz. Just a number. [speedup1] d. What is the speedup from the original time calculated in part b if the clock rate is improved to 5 GHz and type 3 instructions are improved to 2 CPI? Just a number.  Two numbers after the decimal point. [speedup2]    

Describe what a register is.  

The image above is a result of a SPEC2017 Benchmark Test. What is the result (without optimization)? What does this result mean? What is the clock rate of the processor?

Name one thing defined by an instruction set architecture.

What is the most likely cause of Ms Lewis’ acid-base imbalance? 

Updated Clinical Presentation: Ms. Lewis’s respiratory rate has further increased to 40 breaths per minute. Oxygen saturation has dropped to 88% on supplemental oxygen. She exhibits increased restlessness, confusion, and lethargy. Breath sounds reveal diminished air entry bilaterally. Laboratory Results Arterial Blood Gas pH 7.30 PaCO2 58 HCO3 24 mEq/L Serum electrolytes: Na+ 140 mEq/L, K+ 4.2 mEq/L, Cl- 98 mEq/L, CO2 42 mEq/L Identify the new acid-base disorder based on the updated ABG results.

According to Laplace’s Law, A larger alveoli compared to a smaller alveoli would:I. Expand easierII. Have greater pressureIII. Have a lower surface tensionIV. Decrese in radius

Robert boyle is credited for Boyle’s Law, this law states that:
