Hi, I tried to compile my petsc application (c++) on AIX6.1 with POE by IBM xlc (mpCC_r in fact) on PPC6. The serial code (with mpi uni) runs ok. However, parallel code always crash with error message ERROR: 0031-250 task 0: IOT/Abort trap And a core dumped.
dbx gives little message about the core bash-3.00$ dbx ~/packages/genius/bin/genius.AIX core Type 'help' for help. Core file "core" is older than current program (ignored) reading symbolic information ... (dbx) where ustart() at 0x9fffffff0000240 The petsc is configured by CONFIGURE_OPTIONS = --known-level1-dcache-size=32768 --known-level1-dcache-linesize=32 --known-level1-dcache-assoc=2 --known-memcmp-ok=1 --known-endian=big --known-sizeof-char=1 --known-sizeof-void-p=8 --known-sizeof-short=2 --known-sizeof-int=4 --known-sizeof-long=8 --known-sizeof-long-long=8 --known-sizeof-float=4 --known-sizeof-double=8 --known-sizeof-size_t=8 --known-bits-per-byte=8 --known-sizeof-MPI_Comm=4 --known-sizeof-MPI_Fint=4 --known-mpi-long-double=1 --download-f-blas-lapack=1 --download-mumps=1 --download-blacs=1 --download-parmetis=1 --download-scalapack=1 --download-superlu=1 --with-debugging=0 --with-cc=\"mpcc_r -q64\" --with-fc=\"mpxlf_r -q64\" --with-batch=1 --with-shared-libraries=1 --known-mpi-shared-libraries=1 --with-x=0 --with-pic=1 It seems petsc example works well. NOTE, petsc is compiled as c library, my application is c++, which links petsc library. My code should stable enough, it works well on Linux/windows, and do not have memory problem (checked by valgrind). I guess there are some compile/link issue caused the problem. Does any one have suggestions? Gong Ding
