GASOLINE has been ported to nearly every
parallel platform in existence during the last 10
years

• PVM
• MPI
• KSR
• T3D/E Shmem
• Convex Exemplar
• POSIX Threads
• Quadrics Shmem
• XT3! (MPI)

GASOLINE is able to adapt to new architectures by
conducting all parallel operations though a
Machine Dependent Library (MDL) that contains all
machine-specific parallel functions.
Communication
The MDL is rewritten for each architecture,
allowing GASOLINE to take advantage of the
strength of each new generation of parallel
machines!
