Hi,I'm new to this MPI library. and I need your help.I'm trying to use the library to test the below example code abouta simple matrix multiplication program. AxB=C
- Matrix A is copied to every processor. Matrix B is divided into blocks and
distributed among processors
- The data is distributed among the workers who
perform the actual multiplication in smaller blocks and send back their
results to the master.
This is the example source code:http://www.nccs.gov/wp-content/training/mpi-examples/C/matmul.c
I was able to run A (200_200) * B (200_180). But I could not increase the number of rows / columns anymore.If I runA (200_200) * B (200_200) for 2 processors, I will get the following error message:job aborted:rank: node: exit code[: error message]0: hostname_here: 1231: hostname_here: -1073741571: process 1 exited without calling finalizejob aborted:rank: node: exit code[: error message]0:hostname_here: 1231:hostname_here: -1073741571: process 1 exited without calling finalizeThanks in advance./Eric
