我想用Intel跟踪分析器和收集器来分析mpi程序。我做以下步骤：1 ）mpiicc -trace first.cpp second.cpp -o PROG 2）程序mpiexec -n 3 prog.exe 第2步后，我得到一个错误：mpiexec - 连接到服务的错误
Error connecting to the Service
[[email protected]] ..\hydra\utils\sock\sock.c (270): unable to connect from "crop" to "crop" (No error)
read from stdin failed, error 9.
[[email protected]] ..\hydra\tools\demux\demux_select.c (78): select error (No such file or directory)
[[email protected]] ..\hydra\pm\pmiserv\pmiserv_pmci.c (501): error waiting for event
