+## TAU
+
+Clone it from the public repository:
+```
+git clone https://github.com/UO-OACISS/tau2.git
+```
+
+Compile it. For me:
+```
+./configure -bfd=download -starpu=$STARPU -otf=download
+make -j install
+```
+
+At the end of the compilation, `make` displays the name of the library that was created. For instance: 
+```
+Built /home/users/coti/x86/tau2/x86_64/lib/Makefile.tau-starpu-pthread
+***************** DONE ************************
+```
+
+A few notes:
+- This will enable support for pthreads. It is mandatory to add support for some concurrency, since StarPU is multithreaded. 
+- Support for Cuda can be added, with options like `-cupti` and `-cuda`. I don't have first-hand experience with the OpenCl support, but I know it exists.
+- The last configure command that was executed is kept in `.last_config`. All the configure commands that were executed previously are kept in `.all_config`.
