intMPIAPIMPI_File_write_ordered( _In_ MPI_File file, _In_void*buf,intcount, MPI_Datatype datatype, _Out_ MPI_Status *status ); 参数 file[in] 文件句柄。 buf[in] 缓冲区的初始地址。 计数 缓冲区中的元素数。 datatype 每个缓冲区元素的数据类型。
int MPI_File_write_ordered( MPI_File file_handle, void *buf, int count; MPI_Datatype datatype, MPI_Status *status) file_handle是一个文件句柄的指针,用于随后的文件写入 buf是要发送的数据的指针 count是数据的数量 datatype是写入文件的MPI数据类型 这个函数同样会返回一个状态, 建议每次调用都使用MP...

MPI-2的解决方案 •对通信域进行扩展 –组内通信域–组间通信域 •具体实现方式 –动态派生进程（有父子关系）–独立进程间通信（C/S关系）–Socket通信（转换socket通信）组间通信域的点到点通信 例子 •MPI_SEND(buf,count,datatype,dest,tag,intercomm)•与组内通信的不同：1dest的含义；2intercomm ...

使用开源 VampirTrace 5.5.3 发行版来实现 MPI 跟踪。该跟踪可识别以下 VampirTrace 环境变量: 有关这些变量的更多信息,请参见Technische Universität Dresden Web 站点上的 Vampirtrace 用户手册。 在达到缓冲区限制之后发生的 MPI 事件将不会写入跟踪文件,这将导致跟踪不完整。
