      Above is the result of "cat /proc/meminfo" in SCC Linux.


      As it says, MemTotal is 320MB. However, I know it is 32GB in total and LUT says each core has 640MB.


      I cannot find where in the source code set the data.



      How can I change MemTotal to 640MB???

          The current Linux image only uses 320MB private space.

          Admittedly the LUT says that 40 slots (640MB ) are assigned to a core as priivate but only half of that is used. In fact it is that extra memory that we hijack for shared memory.I think becasue SCC Linux is using 320MB, that is what you should see with cat /proc/meminfo for MemTotal.
