C++ 代码实现高性能异构指令数据竞争分析系统
指令集解析模块（ISA Parser）：
解析不同指令集的指令，提取指令信息。
#include <iostream>
#include <string>
#include <unordered_map>
#include <vector>
// 指令信息结构体
struct Instruction {
std::string name;
std::vector<std::string> operands;
std::string isa;
};
// 指令集解析器类
class ISAParser {
public:
ISAParser() {
// 初始化指令集映射
isa_map["SSE"] = {"ADDPS", "MULPS"};
isa_map["AVX"] = {"VADDPS", "VMULPS"};
isa_map["AVX512"] = {"ZADDPS", "ZMULPS"};
}
// 解析指令
Instruction parseInstruction(const std::string &line) {
Instruction inst;
size_t pos = line.find(' ');
inst.name = line.substr(0, pos);
inst.isa = getISA(inst.name);
inst.operands = parseOperands(line.substr(pos + 1));
return inst;
}
private:
std::unordered_map<std::string, std::vector<std::string>> isa_map;
std::string getISA(const std::string &name) {
for (const auto &isa : isa_map) {
if (std::find(isa.second.begin(), isa.second.end(), name) != isa.second.end()) {
return isa.first;
}
}
return "UNKNOWN";
}
std::vector<std::string> parseOperands(const std::string &operands) {
std::vector<std::string> result;
size_t start = 0, end;
while ((end = operands.find(',', start)) != std::string::npos) {
result.push_back(operands.substr(start, end - start));
start = end + 1;
}
result.push_back(operands.substr(start));
return result;
}
};
int main() {
ISAParser parser;
Instruction inst = parser.parseInstruction("ADDPS xmm0, xmm1");
std::cout << "Instruction: " << inst.name << ", ISA: " << inst.isa << std::endl;
return 0;
}
指令调度模块（Instruction Scheduler）：
处理异构指令的调度，确保指令在适当的时间执行。
#include <iostream>
#include <queue>
#include <string>
#include <vector>
class InstructionScheduler {
public:
void scheduleInstruction(const Instruction &inst) {
instructionQueue.push(inst);
}
void executeInstructions() {
while (!instructionQueue.empty()) {
Instruction inst = instructionQueue.front();
instructionQueue.pop();
execute(inst);
}
}
private:
std::queue<Instruction> instructionQueue;
void execute(const Instruction &inst) {
std::cout << "Executing: " << inst.name << " with ISA: " << inst.isa << std::endl;
// 这里可以加入具体的执行逻辑
}
};
int main() {
InstructionScheduler scheduler;
scheduler.scheduleInstruction({"ADDPS", {"xmm0", "xmm1"}, "SSE"});
scheduler.scheduleInstruction({"VMULPS", {"ymm0", "ymm1"}, "AVX"});
scheduler.executeInstructions();
return 0;
}
数据竞争检测模块（Data Race Detector）：
检测并报告数据竞争。
#include <iostream>
#include <unordered_map>
#include <vector>
class DataRaceDetector {
public:
void addInstruction(const Instruction &inst) {
for (const auto &operand : inst.operands) {
accessMap[operand].push_back(inst);
}
}
void detectDataRaces() {
for (const auto &entry : accessMap) {
if (entry.second.size() > 1) {
reportDataRace(entry.first, entry.second);
}
}
}
private:
std::unordered_map<std::string, std::vector<Instruction>> accessMap;
void reportDataRace(const std::string &operand, const std::vector<Instruction> &insts) {
std::cout << "Data race detected on operand: " << operand << std::endl;
for (const auto &inst : insts) {
std::cout << " Instruction: " << inst.name << " with ISA: " << inst.isa << std::endl;
}
}
};
int main() {
DataRaceDetector detector;
detector.addInstruction({"ADDPS", {"xmm0", "xmm1"}, "SSE"});
detector.addInstruction({"VMULPS", {"xmm0", "ymm1"}, "AVX"});
detector.detectDataRaces();
return 0;
}
性能分析模块（Performance Analyzer）：
分析执行性能，生成报告。
#include <iostream>
#include <chrono>
#include <vector>
class PerformanceAnalyzer {
public:
void startMeasurement() {
start = std::chrono::high_resolution_clock::now();
}
void endMeasurement() {
end = std::chrono::high_resolution_clock::now();
measurements.push_back(std::chrono::duration_cast<std::chrono::microseconds>(end - start).count());
}
void reportPerformance() {
long long total = 0;
for (const auto &measurement : measurements) {
total += measurement;
}
std::cout << "Average execution time: " << total / measurements.size() << " microseconds" << std::endl;
}
private:
std::chrono::high_resolution_clock::time_point start, end;
std::vector<long long> measurements;
};
int main() {
PerformanceAnalyzer analyzer;
analyzer.startMeasurement();
// 这里可以加入要测量的代码
analyzer.endMeasurement();
analyzer.reportPerformance();
return 0;
}
用户界面模块（User Interface）：
提供用户配置和查看结果的界面。
#include <iostream>
#include <vector>
class UserInterface {
public:
void displayMenu() {
std::cout << "1. Parse Instruction" << std::endl;
std::cout << "2. Schedule Instruction" << std::endl;
std::cout << "3. Detect Data Races" << std::endl;
std::cout << "4. Analyze Performance" << std::endl;
std::cout << "5. Exit" << std::endl;
}
int getUserChoice() {
int choice;
std::cout << "Enter your choice: ";
std::cin >> choice;
return choice;
}
void executeChoice(int choice, ISAParser &parser, InstructionScheduler &scheduler, DataRaceDetector &detector, PerformanceAnalyzer &analyzer) {
switch (choice) {
case 1: {
std::string line;
std::cout << "Enter instruction: ";
std::cin.ignore();
std::getline(std::cin, line);
Instruction inst = parser.parseInstruction(line);
std::cout << "Parsed Instruction: " << inst.name << " with ISA: " << inst.isa << std::endl;
break;
}
case 2: {
std::string line;
std::cout << "Enter instruction to schedule: ";
std::cin.ignore();
std::getline(std::cin, line);
Instruction inst = parser.parseInstruction(line);
scheduler.scheduleInstruction(inst);
break;
}
case 3:
detector.detectDataRaces();
break;
case 4:
analyzer.startMeasurement();
scheduler.executeInstructions();
analyzer.endMeasurement();
analyzer.reportPerformance();
break;
case 5:
std::cout << "Exiting..." << std::endl;
exit(0);
default:
std::cout << "Invalid choice!" << std::endl;
}
}
};
int main() {
ISAParser parser;
InstructionScheduler scheduler;
DataRaceDetector detector;
PerformanceAnalyzer analyzer;
UserInterface ui;
while (true) {
ui.displayMenu();
int choice = ui.getUserChoice();
ui.executeChoice(choice, parser, scheduler, detector, analyzer);
}
return 0;
}
