Hi, Whilst working on the Reproducible Builds effort [0], we noticed that llama.cpp could not be built reproducibly. This is because the llama-bench.1 manual page embeds the number of CPUs: │ │ │ ├── ./usr/share/man/man1/llama-bench.1.gz │ │ │ │ ├── llama-bench.1 │ │ │ │ │ @@ -63,15 +63,15 @@ │ │ │ │ │ \fB\-dt\fR, \fB\-\-defrag\-thold\fR <f> │ │ │ │ │ (default: \fB\-1\fR) │ │ │ │ │ .TP │ │ │ │ │ \fB\-t\fR, \fB\-\-threads\fR <n> │ │ │ │ │ -(default: 16) │ │ │ │ │ +(default: 12) │ │ │ │ │ .TP A patch is attached that replaces this nondetermistic value with a placeholder value; the default is still calculated at runtime.
