OpenMPIをインストールし、最新バージョンで提供されているサンプルの1つをコンパイル/実行しようとしました。 mpiexecで実行しようとすると、アドレスはすでに使用中であることがわかります。OpenMPI bind（）エラーで失敗しました既に使用中のアドレス（48）Mac OS X
これはいつも起こっているのですか？
Kristians-MacBook-Pro:examples kristian$ mpicc -o hello hello_c.c
Kristians-MacBook-Pro:examples kristian$ mpiexec -n 4 ./hello

-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:
Process name: [[56076,1],0]
Exit code: 1
