Thanks for your reply!
I am currently testing the potential usage of nvshmem in graph processing, which essentially is irregular memory access application. And I want to build a Pytorch operator for that just like the cuGraph.
I also encounter another problem when compiling my program on a HPC (DGX with 4 Tesla V100 32GB). Because I don’t have the root access for those servers, I have to put the
openmpi on my user home directory
/home/user/opemmpi and I use the command from the official website.
nvcc -rdc=true -ccbin g++ -arch=$NVCC_GENCODE \
-o app \
However, it always fails to link with
mpi_cxx while it can successfully link with
mpi, and it shows me like
/usr/bin/ld: cannot find -lmpi_cxx
Could you please help me with this?
Thanks a lot!
