However, today, less than 10% of manufacturers are using HPC servers for computer simulations to design and develop their products, according to the two studies, ‘Reflect’ and ‘Reveal’, from the US Council of Competitiveness.
There are two realistic options today how to acquire additional HPC computing power beyond what is available from the desktop system. In addition, there are often long and painful internal procurement and approval processes, and additional skills and manpower are needed to operate and maintain such a system. However, with the advent of cloud computing, a second viable option arose for SMEs to experience the benefits from HPC without having to buy and operate their own HPC system.
The IDC study found (see the figure above), that only 7% of the total cost of acquiring and operating an HPC system over three years is coming from the hardware. To estimate the cost for a realistic SME scenario, we assume a company needs to run a mix of simulation jobs, most of them running on 32 cores, and some larger jobs with more fine-grained geometry and more sophisticated physics on 256 cores. Now, according to IDC, the Total Cost of Ownership of such a system is $1M over three years, $333K per year for 256 cores, or $1,302 per core per year, or $0.149 for one core per hour (core hour), if you are utilizing this system 100%. Table: Cost per core per hour for a an HPC server with 16 compute nodes (256 cores), depending on the number of busy nodes (utilization).
According to the above table, the cost of the in-cloud solution (with $0.20 per core hour, Feb.
Now, that’s an easy one, because you just ask your HPC Cloud provider how much one core costs per hour. Now let’s go back to the above scenario of a company that needs to run a mix of 32-core and 256-core simulation jobs, at an average utilization of 20% of this system. Stamp style notary seals can be purchased from various places online for anything from $18 - $25. In your music videos--which have over 10 million views--you skydive, streak, and so much more. Comparing the cost of living between 1975 and 2015: you are being lied and fooled when it comes to inflation data and the cost of living posted by mybudget360 in.
Steve inskeep host: the government says social security beneficiaries will not be getting a cost of living increase in 2016. Cost of living vs wage stagnation in the united states, 19792015 inflationadjusted wages haven't gone up, the cost of living has for the most part gone. I read with interest your definition of the `living wage` but you actually use the government phrase and the real calculation is by the living wage foundation.. In public policy a living wage is the minimum income necessary for a worker to meet their basic needs.

This week first Google and then AWS announced significant new price changes that will be very attractive to many cloud users. The vast majority (over 90%) of the companies perform virtual prototyping and large-scale data modeling still limited by their desktop computers (workstations or laptops). One option (which is widely proven to work) is buying an HPC server which is many times faster and more capable than what engineers currently have available on their desk. Still, buying an HPC server is one possible option, and it was the only one until recently.
HPC in the Cloud allows the SME engineers to continue using their own desktop system for daily design and development work, and to submit (burst) the (sometimes much) larger, more complex, more time-consuming jobs into the cloud. The much bigger portion of the pie is coming from the high cost of expertise (staffing), equipment, maintenance, middleware, and training. Therefore, the company decides to buy a typical 16-node HPC system, each node having 2 CPUs with 16 cores (resulting in 256 cores in total), to be able to perform the 32-core runs as well as the 256-core runs.
Searching on Google for ‘average server utilization’, however, you find most often utilization rates between 5% and 20%, usually due to a peak-and-valley utilization pattern caused by varying workloads and day time (certainly, you will also find utilization of 90% when e.g. 2014*) will exceed the one for the in-house solution only at about 75% (and higher) average utilization of the in-house HPC cluster, a situation which we only heard of from academic or big-industry Supercomputing Centers serving hundreds or even thousands of users. At the time of this writing (February 2014) a reasonable price for one core hour on a similar powerful HPC system in the cloud is about $0.20 (not including additional services and application software of course). We assume the 32-core workload utilizes a small in-house HPC cluster with two 16-core nodes, to accommodate all the 32-core jobs.

But 57% of these companies said that they have application problems that they can’t solve with their existing desktop computers, because their desktops are too slow for the problems they want to solve, or because geometry or physics are too complex and need more memory than is available from their desktop. However, for many companies, especially SMEs, buying an HPC server is often not a viable solution. Additional benefits of the HPC Cloud solution are on-demand access to ‘infinite’ resources, pay per use, reduced capital expenditure (CAPEX), greater business agility, higher-quality results, lower risk, lower product failure rate, and dynamically scaling resources up and down as needed.
The following analysis just focuses on the system and does not include the application software, which should be analyzed in a similar way. A reasonable price (but for the sake of simple math, still estimated) of such a system would be say $70K.
For 40% utilization, which is not uncommon in HPC, the cost of one core hour is still $0.37.


The workload per year for a 20% utilized cluster is equivalent to 256 cores * 24 hours * 365 days * 20 % = 448,512 core hours, or $89,702 when moved to the cloud. The following table shows the total cost of one core hour for a 16-node (256-core) in-house HPC cluster depending on % utilization (or ‘number of busy nodes’) of this cluster.
Obviously, when compared to $333K above, the cloud option is economically very attractive (in this case 3.7 times better than the in-house option).
With an excellent cluster utilization of for example 92% of this small in-house cluster (to match the 20% utilization of the big cluster mentioned above) the core hour for the small cluster comes to $0.18. The remaining 256-core (16-node) big jobs are running in the cloud, for about one month during the one year (we have to choose 1 month to achieve the above 20% utilization of the big 256-core 16-node in-house cluster), and the core hour in the cloud is again $0.20, resulting in $37K for one month. It is important to note that price drops don’t always target all of a provider’s resources or services. This is good news for enterprises who still allocate the vast majority (70 percent to 90 percent) of cloud spend to compute. In 2013, this only got harder as the frequency of pricing changes increased.Reductions in Compute and Storage Prices AcceleratedWhile the number of compute reductions doubled in 2013, the size of those reductions showed little change. In 2013, the average price reduction for cloud services was 23 percent, which is comparable to the size of drops in 2012 (also 23 percent). It has been leading the way in terms of in both frequency and size of reductions and forcing others to follow.5 Tips for Managing Your Cloud SpendCloud prices continue to drop, making the unit cost of cloud computing even more attractive compared to traditional data centers.
As usage grows, especially in large enterprises, public cloud bills become an increasingly significant line item in IT budgets. You need to account for variables that only you can predict, for example the future launch of a major product or campaign, or seasonal trends. Be sure to have tools or processes in place that allow for estimating the costs of your entire cloud portfolio, including private and hybrid clouds. Often the cost of instances left running unnecessarily or services that are overprovisioned can far outweigh price reductions from a cloud provider.
RightScale customers use features like automation, alerts, monitoring, and auto-scaling to avoid wasted resources and wasted spending.
Many enterprises have a portfolio of cloud services, including public and private, to meet the requirements of varied applications. However once you identify a change that you want to make, you’ll need a way to take action on those changes. RightScale is a trusted partner with solutions and services that help you visualize, forecast, and optimize your cloud costs.
