Please provide your OS version, the installed perl version and the perl environment variables.

Moreover, in this script ./perl/generatePas.pl (subfolder bench) is a print statement for these cases: https://github.com/RRZE-HPC/likwid/blob/master/bench/perl/generatePas.pl#L200

Please comment the line in and run again.

@TomTheBear Thanks for replying. My environment is

# uname -a
Linux localhost.localdomain 6.0.7-301.fc37.x86_64 #1 SMP PREEMPT_DYNAMIC Fri Nov 4 18:35:48 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
[root@10 likwid-5.2.2]# perl --version

This is perl 5, version 36, subversion 1 (v5.36.1) built for x86_64-linux-thread-multi

I comment the line in and output is :

Thanks for the output. I asked @moebiusband73 as he is the original author of this Perl script.

In the meantime, try this ($LIKWID_SRC is your downloaded version):

$ mkdir -p $HOME/.likwid/bench/x86-64
$ mv $LIKWID_SRC/bench/x86-64/* $HOME/.likwid/bench/x86-64
$ cd $LIKWID_SRC
$ make distclean && make && (sudo) make install

There are two ways how the assembly kernels are loaded. Either they are compiled in at build time or they are generated on-the-fly. With above commands, no kernel will be compiled into likwid-bench, all will be generated on-the-fly.
