SSS-CORE provides a brandnew software distributed shared
memory ``Asymmetric Distributed Shared Memory (ADSM)''using Memory
Based Communication Facilities. The ADSM executes a shared-read
operation as a single load instruction. As for a shared-write
operation, the compiler detects it and translates it into the
corresponding local-store instruction and instructions for consistency
management. In order to reduce communication overhead and runtime
overhead, we propose an optimizing algorithm for coalescing a sequence 
of instructions for consistency management.  The coalescing algorithm
is evaluated using the SPLASH-2 benchmark on SSS-CORE.
