Shared Memory

• Asynchronous atomic access to shared objects
• Each PC has a copy, always up-to-date
• C++ templates intercept operations on shared objects
  • Lvalue store causes s_write(a, s);
    Signal and update, ~60 us typical
  • Rvalue fetch causes s_poll();
    Poll and local fetch, ~1 us
• Load balancing shared-memory Mandelbrot achieves > 250 MFLOPS using 4 Pentium 90 TTL_PAPERS
