主题:Fotran中最简单的MPI例子报错
各位大虾:
本人正在学习MPI,今天刚刚运行了第一个例子,是一个最简单的Send-receive的例子,但是程序执行时报错了,请问这是怎么回事?
附上程序段:
program main
use mpiinteger a(10)
integer myrank,ierr,rc
call MPI_INIT(ierr)
call MPI_COMM_RANK(MPI_COMM_WORLD,myrank,ierr)
if(myrank==1) then
a=1
call MPI_SEND(a,10,MPI_INTEGER,0,99,MPI_COMM_WORLD,ierr)
else
call MPI_RECV(a,20,MPI_INTEGER,1,99,MPI_COMM_WORLD,ierr)
print *,"received:",a
endif
call MPI_FINALIZE(rc)
end
报错情况
