3.6.2 Use of the NCAR Mass Storage System
When run on any of the NCAR computer systems, CCM3.6 uses the NCAR Mass
Store System for archival storage of output datasets. Input and output
datasets are copied between local disk and the MSS and accessed either
via Fortran-callable routines, or via a shell command. Data are staged
from the MSS to disk via msread (available both as a Fortran routine
or a shell command). These requests are issued as synchronous operations.
Hence, the model will wait until an msread is completed before resuming
execution. However, mswrite commands (which stage data from disk
to the MSS) are normally issued asynchronously for efficiency reasons.
Asynchronous writes to the MSS are made by calling NCAR-specific routine mswrite
with the nowait option. This allows the time integration to continue
without having to wait for the file to reach the Mass Store.
