Multitude of JVM - misinterpreted ;)

TPM is bragging about the SPECjbb2005 performance of the p7 system. Interestingly he is talking about the nonsensical benchmark again: Multiple JVMs per system with 32 bit. As i wrote before: When you want a cluster, buy a cluster and don’t build one for an embarrassingly parallel problem in a box. I think, that the only relevant test today is 1 JVM/64-bit today. By the way: Those multitude of JVMs/32-bit doesn’t use the real advantage of the big machines (large heaps for you application), however it’s the only chance those SGI systems or extremly-NUMA systems can compete with larger SMP systems, because of the vastly reduced interconnect usage (which is quite useful to avoid the long arm of Amdahl’s law)
