- What is the difference between dynamic and static libraries? A. Dynamic libraries are linked when executable libraries are added to memory, and static libraries are inked alter the program is placed in the memory B. Dynamic libraries are much larger than static libraries because external programs are built in the executable file that is added to memory C. Static libraries are linked when executable libraries are added to memory, and dynamic libraries are linked after the program is placed in the memory D. Static libraries can be linked to any program at run time however, the program has to be loaded for the dynamic library code to be usedarrow_forwardPlease use C++ to create this programarrow_forward219. The situation when two or more programs hung up is referred as a. Multiprogramming b. Failed Mutual Exclusion c. Deadlocks d. Improper Synchronizationarrow_forward
- B Exercise Timings parSapply() Running the dice game is embarrassingly parallel. These types of simulations usually (but not always) produce a good speed-up. As before, we can use microbenchmark() or system.time(). For simplicity, we'll use system.time() in this exercise. Instructions The play() function has been defined in your workspace. We'll assume that we want to play one hundred thousand games. Set no_of_games to 1e5. • Use system.time() to time play() being repeatedly called in serial. • Call sapply() with 1:no_of_games and the play() wrapper function. • Assign the result to serial. • Wrap this call in system.time() to time it. • Create a 4 core cluster object and export the play() function to it. • Use system.time() to time play() being repeatedly called in parallel. • Rework the code you used to create serial, but make it work in parallel. < script.R 1 # Set the number of games to play no_of_games <- 1e5 23 J 4 5 6 7 8 9 10 982LZ 11 12 13 # Time serial version system.time…arrow_forwardExplain what you mean by "execution flow."arrow_forwardExample: The Problem Input File Using C programming language write a program that simulates a variant of the Tiny Machine Architecture. In this implementation memory (RAM) is split into Instruction Memory (IM) and Data Memory (DM). Your code must implement the basic instruction set architecture (ISA) of the Tiny Machine Architecture: //IN 5 //OUT 7 //STORE O //IN 5 //OUT 7 //STORE 1 //LOAD O //SUB 1 55 67 30 55 67 1 LOAD 2- ADD 3> STORE 4> SUB 5> IN 6> OUT 7> END 8> JMP 9> SKIPZ 31 10 41 30 //STORE O 67 //OUT 7 11 /LOAD 1 //OUT 7 //END 67 70 Output Specifications Each piece of the architecture must be accurately represented in your code (Instruction Register, Program Counter, Memory Address Registers, Instruction Memory, Data Memory, Memory Data Registers, and Accumulator). Data Memory will be represented by an integer array. Your Program Counter will begin pointing to the first instruction of the program. Your simulator should provide output according to the input file. Along with…arrow_forward
- While statements may start and stop anywhere in the flexible manner popularized by Algol60, most modern programming languages insist that statements finish with an end sign like a semicolon or colon. To the contrary, Python and a handful of other programming languages adhere to a set structure in which statements start in a certain column and stop at the end of a line of code unless continuation marks are provided for each statement. Discover how readability, writability, and security are affected by a file's fixed or free format in the following paragraphs.arrow_forwardWhen are examinations of queue processes recommended to be carried out?arrow_forwardIf I may ask, what exactly do you mean by "execution flow?"arrow_forward
