Nvfortran 23.9 problem

Accelerated Computing HPC Compilers nvc, nvc++ and nvfortran
13

I installed the HPC SDK Version 23.11 today and also noticing slow compilation and standard output compared to g++ and clang++.

g++

$ time g++ -o llil4hmap -std=c++20 -fopenmp -Wall -O3 llil4hmap.cc -I./parallel-hashmap

real  0m3.574s
user  0m3.441s
sys   0m0.124s

$ ./llil4hmap /data1/input/big* | cksum
llil4hmap (fixed string length=12) start
use OpenMP
use boost sort
get properties         3.759 secs
hmap to vector         1.043 secs
vector stable sort     1.715 secs
write stdout           0.868 secs
total time             7.386 secs
    count lines     323398400
    count unique    200483043

clang++

$ time clang++ -o llil4hmap -std=c++20 -fopenmp -Wall -O3 llil4hmap.cc -I./parallel-hashmap
