-BLIS Installation Manual
-------------------------
-
-BLIS is a portable software framework for high-performance BLAS-like dense linear algebra libraries. It has received awards and recognition, including the 2023 James H. Wilkinson Prize for Numerical Software and the 2020 SIAM Activity Group on Supercomputing Best Paper Prize. BLIS provides a new BLAS-like API and a compatibility layer for traditional BLAS routine calls. It offers features such as object-based API, typed API, BLAS and CBLAS compatibility layers.
-
-Project URL: https://github.com/flame/blis
-
-### Prepare:
-
-Compile BLIS:
-
-```bash
-git clone https://github.com/flame/blis
-cd blis
-./configure --enable-cblas -t openmp,pthreads auto
-# will install to /usr/local/ by default.
-make -j
-```
-
-Install BLIS:
-
-```bash
-sudo make install
-```
-
-We recommend using openmp since it's easier to modify the cores been used.
-
-### llama.cpp compilation
-
-Makefile:
-
-```bash
-make LLAMA_BLIS=1 -j
-# make LLAMA_BLIS=1 benchmark-matmult
-```
-
-CMake:
-
-```bash
-mkdir build
-cd build
-cmake -DLLAMA_BLAS=ON -DLLAMA_BLAS_VENDOR=FLAME ..
-make -j
-```
-
-### llama.cpp execution
-
-According to the BLIS documentation, we could set the following
-environment variables to modify the behavior of openmp:
-
-```
-export GOMP_GPU_AFFINITY="0-19"
-export BLIS_NUM_THREADS=14
-```
-
-And then run the binaries as normal.
-
-
-### Intel specific issue
-
-Some might get the error message saying that `libimf.so` cannot be found.
-Please follow this [stackoverflow page](https://stackoverflow.com/questions/70687930/intel-oneapi-2022-libimf-so-no-such-file-or-directory-during-openmpi-compila).

--   `--prompt-cache FNAME`: Specify a file to cache the model state after the initial prompt. This can significantly speed up the startup time when you're using longer prompts. The file is created during the first run and is reused and updated in subsequent runs.
+-   `--session FNAME`: Specify a file to load/save the session, which caches the model state after the initial prompt. This can significantly speed up the startup time when you're using longer prompts. The session file is created during the first run and is reused in subsequent runs. If you change your prompt such that 75% or less of the session is reusable, the existing session file will be overwritten with a new, updated version to maintain optimal performance.
