  • Method Details

    • lcq_singlehost

      public static void lcq_singlehost() throws Exception
      Demonstrates a layered CQ model with a single host (lcq_singlehost.ipynb). This example shows a basic layered queueing network where software tasks execute on a single host. The model captures both software contention (at the task level) and hardware contention (at the host level), typical in client-server architectures. Features: - Single host with multiple software tasks - Nested queueing structure (software and hardware layers) - Analysis of software bottlenecks vs. hardware bottlenecks - Mean value analysis for layered networks
      Throws:
      Exception - if the solver encounters an error

    • lcq_threehosts

      public static void lcq_threehosts() throws Exception
      Demonstrates a layered CQ model with three hosts (lcq_threehosts.ipynb). This example extends the single host case to a distributed system with three hosts. Different software tasks are deployed on different hosts, creating a more complex interaction pattern typical of multi-tier architectures. Features: - Three hosts with distributed software tasks - Inter-host communication patterns - Analysis of distributed system bottlenecks - Load balancing considerations in layered networks
      Throws:
      Exception - if the solver encounters an error

    • lcq_async_cache

      public static void lcq_async_cache() throws Exception
      Layered cache queueing model with ASYNCHRONOUS (non-blocking) cache access (lcq_async_cache.m). The client makes an asynchronous call to the cache and continues without waiting for the reply, which is what a prefetch or a cache warm-up does; the cache still resolves the request through POST_CACHE hit/miss branching. Compare with lcq_singlehost(), whose call is synchronous.
      Throws:
      Exception - if the solver encounters an error

    • main

      public static void main(String[] args)
      Main method to run all layered CQ examples.
      Parameters:
      args - command line arguments (not used)
