 Optimal way to run an MPI program depends on its memory requirements, memory access pattern and communication pattern.
 
-Consider these ways to run an MPI program:
-1\. One MPI process per node, 24 threads per process
-2\. Two MPI processes per node, 12 threads per process
-3\. 24 MPI processes per node, 1 thread per process.

+    Consider these ways to run an MPI program:
+
+    1. One MPI process per node, 24 threads per process
+    2. Two MPI processes per node, 12 threads per process
+    3. 24 MPI processes per node, 1 thread per process.
 
 **One MPI** process per node, using 24 threads, is most useful for memory demanding applications, that make good use of processor cache memory and are not memory bound.  This is also a preferred way for communication intensive applications as one process per node enjoys full bandwidth access to the network interface.
