Objective MPI (Message passing Interface) messaging interface It's not an agreement, but its status has actually been a deal. It is mainly used for parallel program communication in distributed storage System. MPI is a function library, which can be called through Fortran and C programs, the advantage of MPI is that it is faster and better portability. Cluster

The basic idea is to divide a large matrix by rows, each processor (or compute node, note that the nodes on the distributed supercomputer, not the nodes in the graph) are responsible for several rows in the matrix, for example, our matrix size is 16 16, ready to be

Concurrent programming with a very popular Boost library is interesting. Boost has several libraries for concurrent programming: the Interprocess (IPC) library is used to implement shared memory, memory mapped I/O, and Message Queuing; The thread library is used to implement portable multithreading; Message passing Interface (MPI) Libraries are used for message passing in distributed computing; The Asio Library is used to implement portable networking

Point-to-point communication requires that the send and Recv pairs be available. Point-to-point communication has 12 pairs, corresponding to the blocking mode 1 group (4) and non-blocking mode 2 groups respectively Category Send Accept Description Blocking Communication Mpi_sendMpi_bsendMpi_rsendMpi_ssend Mpi_recvMpi_irecvMpi_recv_init If the accepted action is usedMpi_irecvMpi_recv_init, use the mpi_request object for testing.

If our parallel program uses the I/O function defined by MPI (romio library in mpich), then, we have some special features When configuring NFS: 1. the NFS version must be at least 3. 2. The nfslock service must be enabled. 3. When the NFS Directory of the Mount master node is defined in the/etc/fstab file of the node, option ults cannot be entered in the option column. At least noac (no attribute cache) must be set) this option is matched (this conf
