`python run_benchmark.py -b cholesky2 -f dace_cpu` does not work on Macbook

[pratyai]

I have been trying to run the benchmarks on my 2019 (Intel) Macbook and this particular benchmark + framework combination seems broken on that machine. I get the following error (truncated; full error):

[ 25%] Linking CXX shared library libfusion.dylib
Undefined symbols for architecture x86_64:
  "_LAPACKE_dpotrf", referenced from:
      __program_fusion_internal(fusion_state_t*, double*, long long) in fusion.cpp.o

clang++: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [libfusion.dylib] Error 1
make[1]: *** [CMakeFiles/fusion.dir/all] Error 2

On the other hand, on a linux machine, everything seems to go just fine. I have not tried with the newer (M1) Macs, so perhaps it is only present in the older Macbooks.

Side-note: the dependency installation does not exactly work as stated in README.md for me. I now have the following changes to explicitly include additional dependencies:

This looks like it is related to MacOS and DaCe. Have you tried the MacOS instructions in https://spcldace.readthedocs.io/en/latest/setup/installation.html#common-issues-with-the-dace-python-module ?

I am using ~/.dace.conf to 1) use openblas library (installed through homebrew), and 2) select g++ or clang++ compilers (both installed through homebrew). Not quite sure if there is anything else significant from the common-issues page re. MacOS usage.

I show the errors for both compiler options below --- although, for GCC, all the benchmark programs break the same way, where for Clang, only a small number of benchmarks like cholesky2 break.

Keep in mind that not all DaCe configurations necessarily work for all benchmarks, although there is an effort to address such issues. The Clang error seems related to a problem linking to the BLAS/LAPACK library. Specifically:

Undefined symbols for architecture x86_64:
"_LAPACKE_dpotrf", referenced from:

POTRF is the LAPACK method for Cholesky decomposition, which the cholesky2 benchmark uses. I do not own a Mac, and I am unable to test it myself. I see that you are using OpenBLAS. Maybe you also need to add -lopenblas to the CPU args?

Unfortunately, I do not have any insight into the g++ error. There looks to be some issue with the stdio.h file, but this is unrelated to DaCe.
