Greetings,
I have a simple mpi program, please find it attached.
I am using valgrind-3.3.0
I run my code with the following command:
mpiexec -n 2 valgrind --gen-suppressions=yes ./mpitest
++++++
my question is about the ( --gen-suppressions=yes).
There are too many suppression that come from MPI and
all I want to be able to see is checks from my code alone.
I am very new to valgrind and I have checked to the best of my ability
and probably have missed it, but is there a way to get valgrind to just add
all the suppression generated from the ( --gen-suppressions=yes) command
into
a local file?
another idea that I tried was to create my own suppression file.
one way to try and suppress MPI issues, that I tried is shown in the
following:
{
<insert a suppression name here>
Memcheck:Cond
fun:VIPKL_list_hcas
fun:viadev_init_parameters
fun:MPID_VIA_Init
fun:MPID_Init
fun:MPIR_Init
fun:*
}
However I get no luck. I have this big research project and it would be
great if anyone can lead
me in the right direction.
With regards,
