+===========================
+Runninng Theano on Mammouth
+===========================
+
+To run Theano on the Mammouth cluster, perform the following steps:
+
+* Make sure to source Fred's .local.bashrc file. It contains all the goodies for using the latest and greatest (optimized) libraries (numpy, scipy, etc.)
+>>> source /home/bastienf/.local.bashrc
+
+* set THEANO_BLAS_LDFLAGS='-lmkl -lguide -fopenmp'
+
+  Note: the -lguide flag works, however the fix should probably be considered temporary.
+  Intel has deprecated libguide.so in favor of the newer library libiomp5.so. However, 
+  both libraries are mutually exclusive and one component (theano, numpy or scipy?) already
+  seems to be using libguide.so (hence -liomp5 causes a linking error when compiling thunks)
+
