+Liballprof-1.0 - Collecting traces from MPI applications
+----------------------------------------------------
+  (Using MPICH version 3.3.1 installed in /usr/local)
+
+  * Prepare liballprof-1.0   
+     `cd ~`  
+     `wget -qO- http://spcl.inf.ethz.ch/Research/Performance/LogGOPSim/liballprof-1.0.tgz | tar xzf -`   
+     `cd liballprof-1.0/`  
+     `./configure`  
+     -> Add `-fPIC` to CFLAGS option in the Makefile  
+
+  * Compile liballprof-1.0  
+     `make`  
+     -> If conflic types error during make command, copy the mpi.h file to /usr/local/include/  
+     `make install`  
+
+  * Generate liballprof library  
+     `cd .libs/`  
+     `gcc -shared -o libConOs.so ../mpipclog.o ../sync.o -L~/liballprof-1.0/.libs -lclog`  
+
+  * Collect Traces using liballprof  
+    e.g., using a hello world mpi application  
+    - `LD_PRELOAD=./libConOs.so mpirun -np 6 ../hello`  
+    The traces are generated in /tmp folder after running above command
