Hello, i am using ncg from tao solver and i wanted to test my code validity in a pc with 4 processors before its execution in a cluster. When i run my code with 2 processes (mpirun -np 2) everything looks to work fine but when i use 3 or more processes i have the following error:
Error: Unable to successfully call PETSc function 'VecAssemblyBegin'. *** Reason: PETSc error code is: 1. *** Where: This error was encountered inside /home/ggrekas/.hashdist/tmp/dolfin-wphma2jn5fuw/dolfin/la/PETScVector.cpp. *** Process: 3 *** *** DOLFIN version: 1.7.0dev *** Git changeset: 3fbd47ec249a3e4bd9d055f8a01b28287c5bcf6a *** ------------------------------------------------------------------------- =================================================================================== = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES = EXIT CODE: 134 = CLEANING UP REMAINING PROCESSES = YOU CAN IGNORE THE BELOW CLEANUP MESSAGES =================================================================================== YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Aborted (signal 6) This typically refers to a problem with your application. Please see the FAQ page for debugging suggestions So, is it an issue that i must report to the tao team? Thank you in advance.
