A second benchmark to compare V40z, V490 and T2000 : iGenRAM v1.2

MrBenchmark iGenRAM v1.2 After our performance investigation on integer& floating-point calculations with iGenCPU , let me present today a second microbenchmark called iGenRAM.

The iGenRAM v1.2 benchmark is a Java-based memory application useful to compare the memory performance of different systems. Based on the functional requirements of the California Lotto, this application is simulating a California lotto play consisting of :
  1. Players play Lotto tickets by choosing series of six numbers. Each thread is simulating 6 million tickets played. To store tickets, memory is allocated in Java in the form of multi-dimensional integer arrays.

  2. The system generates a list of six winning numbers.

  3. The system has to determine which ticket won and for what amount. For this, it needs to browse all tickets and compare to the winning combination.

  4. Total duration of this tasks will produce the throughput in Lotto computed per seconds or iGenRAM_Thp and the iGenRAM_RT average response time.

The pressure on the system is mainly on the memory subsystem , just using a minimal amount of CPU power.

Systems with low memory latency and scalable  memory interconnect  will succeed. We expect good things from the Sun Fire T2000.
