so again, if R and D are constants, increasing P and/or T reduces the contrast among classes, while increasing [Beta] increases it, as was already concluded in Hellerstein [1993, Section IV-A] for the uniprocessor
case of System V.
The impact of e prefetching idea was empirically evaluated for a uniprocessor
that, instead of disks, uses the fast memories of other computers on the same local area network as secondary memory.
This means that it takes more than simple extension of uniprocessor
software ideas to exploit message-passing hardware.
The core of our multiprocessor compiler algorithm is an algorithm we developed earlier for selectively prefetching only those references that are likely to suffer cache misses in a uniprocessor
[Mowry 1994; Mowry et al.
Section 5 shows experimental results based on machine simulation, and Section 6 shows experimental results on the SGI uniprocessor
Although programmers find it not only possible, but easy to write multiprocessor programs in which each process has substantial locality, interactions among processes reduce performance and diminish the benefit of moving from a uniprocessor
to a multiprocessor.
They are not used in smaller two-way or uniprocessor
machines, which have their own Xeon DP and Pentium 4 variants that run faster and offer better bang for the buck.
This work pertains to periodic, hard real-time tasks that share lock-free objects on a uniprocessor
5 times the uniprocessor
rate) to solve a large statistics problem using a finite element model.
Available as an extremely area- and power-efficient uniprocessor
or up to a 4x multicore processor, the Cortex-A5 processor unleashes the outstanding performance and power scalability required for the compelling usage scenarios demanded by each of these markets.
The numbers from Gartner show that Hewlett-Packard is still losing a little market share as it wrestles with absorbing Compaq, but the untold story - and one that Gartner's latest report does not discuss - is that the uniprocessor
market that IBM, Dell, and Fujitsu Siemens have pursued very aggressively accounts for a large portion, but certainly not all, of unit sales growth.
In the last 25 years we have seen a 100-fold increase in uniprocessor
