New Amazon EC2 Instance Type - The Cluster Compute Instance
- thu 16y agoWith 880 Cluster Compute Instances (7040 cores): > This result places us at position 146 on the Top500 list of supercomputers. And $1408 per hour.
- tomjen3 16y agoConsidering how much you would have to pay for the power alone, that doesn't seem unfair.
- mullr 16y agoI wonder how that compares to the cost of booking time on a system of similar class, assuming said systems can be booked?
- c1sc0 16y agoIf it's a one-off computation then a few thousand for a relatively hassle-free setup is bearable for many use cases. I've seen many clusters running idle just because customers initially bought more metal than they could handle. Peak load != continuous load.
- usaar333 16y agoUsing extra large high cpu instances is actually cheaper per compute unit. You just lose io and memory.
- garyrichardson 16y agoExactly. All that compute power may not be useful if you need the io/memory.
- cl3m 16y ago> (1 759.00 / 41.82) * 880 * 1.60 = 59222.1903 And for almost 60k per hour, you will be number 1! How long till AWS as the capacity to top the chart?
- frisco 16y agoThe post is signed quite ambiguously "Jeff". Given that it's Amazon making a fairly large announcement here, they could do to include a last name there...
- petercooper 16y agoEach Cluster Compute Instance consists of a pair of quad-core Intel "Nehalem" X5570 processors with a total of 33.5 ECU (EC2 Compute Units) Aha, we finally have another EC2 Compute Unit comparison than the vague "1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor." The X5570 is basically a server grade 2.93GHz Core i7 and it equates to 16.75 ECU (since the "pair" is 33.5 ECU). You can then do very vague and imprecise extrapolation and assume a regular 2.66-2.8GHz i7 is in the 12-15 ECU area (which makes most EC2 instances look rather anemic and probably explains why the Redis benchmarks on EC2 seem so poor.)
- DanBlake 16y agoYeah man, Ive been telling people for a while that ec2's offerings are high priced and low powered. Never would have thought a single i7 would be more than 12x the power of a ec2 standard unit though. crazy
- mtw 16y agoif you're hosting a website, makes more sense to rent dedicated servers. ec2 is great for off-loading peak traffic though
- zemaj 16y agoI don't agree. I've ditched almost all my dedicated servers across all kinds of apps that I run. I now use Rackspace cloud servers as my universal tool for everything I can. I used to use EC2, but I've found I get significantly better performance (and of course support) at Rackspace for the same price. Also avoid Rackspace cloud sites, performance is pretty awful. Anyway back to the dedicated server point. If you use virtual servers you can very easily replicate images, spin up copies and scale your computer power on the fly. Case in point, I was running one of my apps on a $10 pm instance on Rackspace. We got a Techcrunch article out of nowhere and the site instantly died under the traffic. I resized the server on the fly and boom, * straight back up. Once the peak died down I scaled the server back down. A couple of months down the track we get near Techcrunch traffic every day and I haven't had to scale the code base at all - I just keep it running on a larger instance. Much, much more cost effective. * ok not straight. Unfortunately when resizing a Rackspace cloud instance under heavy load it takes ages to run (30+ min isn't unusual compared with 5 min under light load). I've found that the best solution is to spin up a copy on another instance and change the dns to point to the new one. I wish Rackspace would add some way to temporarily block traffic to a server to it can scale. Some kind of "panic", scale me up, button would be great.
- monimaria 16y agoNice post. I enjoy this post gorgeously with all of my friends. Really nice....Thank you for all your hard work. I always enjoy seeing who is picked and enjoy reading that post. http://online-insurance-quotes.org http://online-insurance-quotes.org
- gmosx 16y agohmm.. AWS is evolving relentlessly, GAE engineers should work harder (and faster) to catch up... It will be an interesting battle (and let's not forget about Microsoft, or even Apple)
- helium 16y agoAny good ideas what you could use this for?
- mtw 16y agocrunching numbers (such as estimating where the oil spill is expanding, weather prediction, etc.)
- RK 16y agoMy research group has been doing HPC type stuff on EC2. In fact the press release copy for this sounds almost exactly like what we've been writing when trawling for cash. Of course Amazon also gave us a grant (in AWS credits), so maybe we shouldn't feel bad if any of it was directly lifted...
- tszming 16y agoIt is interesting that the new Cluster Compute Instances use HVM instead of paravirtualization, does it mean AWS is moving away from Xen?
- ericb 16y agoWith so many different options, it makes me wonder if they could do a choose-your-own setup and pay by the core/memory/disk you select.
- jread 16y agoThis new cluster compute instance size is essentially a variation of the m2.4xlarge instance (2xX5550 Nehelem - 27ECUs) with the following changes: 1. Faster X5570 CPUs 2. 10G Network 3. HVM I think the most noteworthy feature is the 10G Nic which is more conducive to clustering than the standard GigE Nic for other instance sizes. I'm not aware of any other public IaaS provider offering 10G network currently. In terms of raw performance the x5570 will probably perform very well relative to other IaaS providers. EC2 is one of the few IaaS clouds that utilizes a heterogenous hardware environment to enable better scalability between instance sizes. Other providers like Rackspace Cloud use homogenous environments (Opteron 2374 in the case of Rackspace) and rely on Hypervisor CPU throttling to enable CPU scaling between different instance sizes. On the low end homogenous clouds tend to offer better value but are not well suited for HPC application on the high end (e.g. a 2GB Rackspace Cloud server kills an EC2 m1.small, but the largest 16GB instance lags far behind EC2 m2.* instances). In fact in some homogenous clouds CPU performance is fairly constant from small to larger sized instances (you are essentially just paying for more memory). I recently wrote a blog post comparing CPU performance of 20 different IaaS providers including EC2 and Rackspace Cloud. In it I used a compilation of 19 different CPU related benchmarks to produce an ECU metric for about 150 different cloud server configurations: http://blog.cloudharmony.com/2010/05/what-is-ecu-cpu-benchmarking-in-cloud.html http://blog.cloudharmony.com/2010/05/what-is-ecu-cpu-benchma...

- neilc 16y agoI think the most noteworthy feature is the 10G Nic The NIC is not the most interesting part, but the network is: not only do these new instances offer 10 GigE, but they also offer full bisection bandwidth to all instances in a placement group (=> no oversubscription of core switches). That is pretty unusual, and a big win for network-intensive applications.
