HI,
In my MPI program, master send many msaages to another worker with the same
tag.
The worker uses sMPI::COMM_WORLD.Recv(&message_para_to_one_worker, 1,
message_para_to_workers_type, 0, downStreamTaskTag);
to receive the messages
I got error:
n36:94880] *** An error occurred in MPI_Recv[n
Hi Jack
Usually MPI_ERR_TRUNCATE means that the buffer you use in MPI_Recv
(or MPI::COMM_WORLD.Recv) is too sdmall to hold the message coming in.
Check your code to make sure you assign enough memory to your buffers.
regards
Jody

Hi
On a newly installed 64bit linux (2.6.32-gentoo-r7) with gcc version 4.4.4
i can't compile even simple Open-MPI applications (OpenMPI 1.4.2).
The message is:

Have you tried using mpicxx, or mpic++ ?

I am able to build on Linux systems with Sun C 5.11 using gcc-4.1.2.
Still trying to get a version of gcc 4.3.4 compiled on our systems so I
can use it with Sun C 5.11 to build OMPI.

I use
double* recvArray = new double[buffersize];
The receive buffer size
MPI::COMM_WORLD.Recv(&(recvDataArray[0]), xVSize, MPI_DOUBLE, 0, mytaskTag);
delete [] recvArray ;
In first iteration, the receiver works well.
But, in second iteration ,
I got the
MPI_ERR_TRUNCATE: message trun
I am trying to install OpenMPI (1.4.3) in a MacPro system running OS X 10.6.4.
I have installed xcode and gfortran.
When I run ./configure --prefix=/opt/openmpi 2>&1 | tee config.out
After some time I get the message ./configure: line 150073:
ompi/mca/io/romio/romio/localdefs: No such file or dir
Jack, in order to see what the problem is, you need to post a more complete
code, such as the code you used for the send, and any manipulation you did
to your recvArray.
