Abstract:
Big Physics applications require computational power solving problems
with demanding real-time constraints. Typically, channels acquire in
real-time to feed mathematical routines generating outputs to interact
with real world processes. Channels may number 100 to 100,000; real-time
constraints may be one millisecond or less per cycle. The underlying
mathematics must be sophisticated to support calculation for this
real-time setting. One approach calls for specialized hardware and
allied codes. Flexibility is lost, though: change propagates through the
system to translate into weeks of re-programming. We report on an
alternative approach based on LabVIEW. The test case is an extremely
large telescope currently in the design and specification phase. The
design, simulation and real-time deployment cycle is executed while
maintaining the high-level purpose of the system; even fundamental
changes in design and mathematics map well to deployment.
