....through with a block size of 32 bytes. The SLC is 4 way set associative and write back with a block size of 64 bytes. The attraction memory is also 4 way set associative, and its block size is 128 bytes. The page size is 4 KB for all simulations. The timing and network model are the same as in [21]. An FLC hit has no latency charge and an SLC hit takes 6 cycles. A hit in attraction memory takes 74 cycles. The network is an 8 bit wide crossbar clocked at 100Mhz. An 8 byte request takes 16 cycles and a message containing a block takes 272 cycles. We only simulate shared data accesses. Random ....

....set in our evaluation. It shows, that without even trying we observe a very uniform pressure on every global set. This is because program locality is maximized in the virtual space. In the physical space, locality only exists within a page. Our experience with allocating memory in physical COMA [21] has taught us that the intervention of the memory management unit can result in disastrous albeit well intended physical page allocations for COMAs. In fact, the advantages of this memory structure are very attractive. As a machine running on virtual addresses, VCOMA provides a simple and ....
