I'm working on some very simple aggregations on huge chunks of offheap memory (500GB+) for a hackaton. This is done using a very simple stride; every iteration the address increases with 20 bytes. So the prefetcher should not have any problems with it.
According to my calculations I'm currently processing 35 GB/s. However I'm not sure if I'm close to the maximum bandwidth of this machine. Specs: 2133 MHz, 24x HP 32GiB 4Rx4 PC4-2133P 2x Intel(R) *Xeon*(R) CPU E5-2687W v3, 3.10GHz, 10 cores per socket What is the best tool to determine the maximum bandwidth of a machine running Linux (RHEL 7) -- You received this message because you are subscribed to the Google Groups "mechanical-sympathy" group.
