压缩包里包含几个用C编写的并行代码，运行无误。其中包括，电路满足性的MP程序，floyd算法MPI代码，Sieve_Eratoshenes筛法MPI代码，矩阵相乘的MPI代码以及计算PI值的OpenMP代码。-Which contains several parallel programs written in C to run correctly. Among them, including Floyd algorithm procedures, matrix multiplication M

矩阵乘法的多线程并行实现，包括：simple，采用openmp对索引顺序ijk（一般写法）的循环实现并行；opt，采用openmp对索引顺序ikj（向量化友好）的循环实现并行；mkl，调用高性能数学库实现矩阵乘法。(Multi-thread parallelization of matrix-matrix multiplication: "simple" case, ijk loop (usual pattern); "opt" case, ikj (ve
