STAN_CPP_OPTIMS=true in make/local results in STAN_CPP_OPTIMS=false in model info #1326
Description
Related to stan-dev/cmdstanpy#794.
In cmdstan directory with no make/local I run:
make examples/bernoulli/bernoulli
./examples/bernoulli/bernoulli infothis gives:
stan_version_major = 2
stan_version_minor = 36
stan_version_patch = 0
STAN_THREADS=false
STAN_MPI=false
STAN_OPENCL=false
STAN_NO_RANGE_CHECKS=false
STAN_CPP_OPTIMS=false
Now if I create a make/local with STAN_CPP_OPTIMS=true and run:
make clean-all
make examples/bernoulli/bernoulli
./examples/bernoulli/bernoulli infoagain gives:
stan_version_major = 2
stan_version_minor = 36
stan_version_patch = 0
STAN_THREADS=false
STAN_MPI=false
STAN_OPENCL=false
STAN_NO_RANGE_CHECKS=false
STAN_CPP_OPTIMS=false
I have confirmed that modifying STAN_THREADS in a similar way successfully reports STAN_THREADS=true from the model info.
I compared the compilation times with/without STAN_CPP_OPTIMS=true by running
make clean-all
time make examples/bernoulli/bernoullifour times, modifying whether STAN_CPP_OPTIMS was present in my make/local each time. This gave:
NO STAN_CPP_OPTIMS
make examples/bernoulli/bernoulli 74.15s user 3.27s system 99% cpu 1:17.63 total
WITH STAN_CPP_OPTIMS
make examples/bernoulli/bernoulli 79.18s user 3.83s system 99% cpu 1:23.26 total
WITH STAN_CPP_OPTIMS
make examples/bernoulli/bernoulli 80.16s user 3.87s system 99% cpu 1:24.28 total
NO STAN_CPP_OPTIMS
make examples/bernoulli/bernoulli 74.68s user 3.30s system 99% cpu 1:18.20 total
So it seems like the options is impacting compilation, perhaps just an issue reporting from model info?
