> Does Puma support timesharing on MPP nodes?
Similar to SUNMOS, Puma is designed for high performance
computing on the compute nodes of the Paragon. It
is performance oriented and supports only basic Unix functionality.
Demand paging is not supported. However, it does support
timesharing on the compute nodes, including the necessary
protections. For instance, a process can create a "window",
but only processes in the same application are allowed
to write to this window, unless another application is given
explicit permission to use the window. Do we need to
specify some protections for MPI get/put?
Under Puma, an application can shoot itself
in the foot, but it is not allowed to harm the OS or
other applications. Puma does not protect an application
Does your SHMALLOC allow me to specify the 'real' address?
Or will it simply malloc space out of my heap and return
this 'real' address?
