Copy the file tcml.tar.gz in a directory whose full path is, say, tcmldir.
Inside tcmldir, do "gunzip tcml.tar.gz" and "tar -xvf tcml.tar" to extract 
the various library files.

Now relink your program that uses WSMP by adding "-ltcmalloc_minimal 
-lstacktrace -lunwind -Ltcmldir" to create the executable.  

For example, if earlier, you were linking as:

icc -o <executable> <your source or object files> -lwsmp64 -L<path of libwsmp64.a> -lpthread -lm

then now you should link as

icc -o <executable> <your source or object files> -lwsmp64 -L<path of libwsmp64.a> -ltcmalloc_minimal -lstacktrace -lunwind -Ltcmldir -lpthread -lm

Before running the executable, set the environment variable LD_LIBRARY_PATH
as follows (depending on your shell):

export LD_LIBRARY_PATH=tcmldir:$LD_LIBRARY_PATH

or

setenv LD_LIBRARY_PATH tcmldir:$LD_LIBRARY_PATH

Note that tcmldir needs to be replaced with the actual path of the
directory where the files extracted from tcml.tar are located.  You 
will need to set LD_LIBRARY_PATH for each session.

When using TCmalloc with MPICH, it is best to set the environment
variable LD_LIBRARY_PATH inside your .cshrc or .bashrc file so that
all MPI processes can load the required shared oibraries.
