Set R: Multiple Radix graphs.
Set 3: Barnes, FMM, Ocean, Water N²

Specifications

Radiosity was run on the following simulated computer:

16 Processors interconnected with a 4 × 4 mesh.
4-byte link width, 1-cycle node-to-node latency (plus waiting).
3-way, 4096-set, physically mapped set-associative cache.
5-cycle cache hit latency, 15 cycle memory-access latency.
Ten-entry, directory-based coherence protocol.
5-entry memory access completion buffer, loads ooowrt stores.
4096-byte VM page size, color-matching page assignment.
64-entry fully associative TLB.
2 instr. / cycle issue rate (not including cache and branch stalls).

Legend Description

The plots show processor activity during execution, there are seven states common to all Proteus (Version 3.11 and 3.12) runs, the other states are application specific. The states are:

Idle: No tasks running.
Busy: Task running, activity unnamed.
Getting Lock: Executing a P semaphore operation.
In barrier, idle: Waiting in barrier, no other activity.
In barrier, busy: In barrier, either executing barrier code or another thread is executing.
Util. off.: Program performing initialization or other activities not appropriate for statistics collection.
Page Relocation: A VM page is being moved between memory modules.
