Until the Phi's came along, we were purchasing 1RU, 4 sockets nodes with
6276's and 256GB ram. On all our codes, we found the throughput to be
greater than any equivalent density Sandy bridge systems (usually 2 x dual
socket in 1RU) at about 10-15% less energy and about 1/3 the price for the
actua
This shows your total ignorence.
At the time several manufacturers claimed specific latencies when
running random through their SSI setups.
So actually *after* i designed the test... ...which for example
proved SGI to have hardware factor 12 slower than they claimed to
have delivered...

Vincent, randomly shuffling a pointer chain is obvious,
and has been done many times before you did it.

Not a single test in HPC tested memory with more than 1 core at the
time.
There were a few pingpong latency tests getting performed single core
by some manufacturers using a raw sort of implementation which wasn't
very realistic.
For software engineers to optimize his software it's crucial

Vincent, you are hillariously full of yourself.
