High Performance Computing – GPU v. CPU

By in SoftLayer, Technology, Tips and Tricks

Sometimes, technical conversations can sound like people are just making up tech-sounding words and acronyms: “If you want HPC to handle Gigaflops of computational operations, you probably need to supplement your server’s CPU and RAM with a GPU or two.” It’s like hearing a shady auto mechanic talk about replacing gaskets on double overhead flange valves or hearing Chris Farley (in Tommy Boy) explain that he was “just checking the specs on the endline for the rotary girder” … You don’t know exactly what they’re talking about, but you’re pretty sure they’re lying.

When we talk about high performance computing (HPC), a natural tendency is to go straight into technical specifications and acronyms, but that makes the learning curve steeper for people who are trying to understand why a solution is better suited for certain types of workloads than technology they are already familiar with. With that in mind, I thought I’d share a quick explanation of graphics processing units (GPUs) in the context of central processing units (CPUs).

The first thing that usually confuses people about GPUs is the name: “Why do I need a graphics processing unit on a server? I don’t need to render the visual textures from Crysis on my database server … A GPU is not going to benefit me.” It’s true that you don’t need cutting-edge graphics on your server, but a GPU’s power isn’t limited to “graphics” operations. The “graphics” part of the name reflects the original intention for kind of processing GPUs perform, but in the last ten years or so, developers and engineers have come to adapt the processing power for more general-purpose computing power.

GPUs were designed in a highly parallel structure that allows large blocks of data to be processed at one time — similar computations are being made on data at the same time (rather than in order). If you assigned the task of rendering a 3D environment to a CPU, it would slow to a crawl — it handles requests more linearly. Because GPUs are better at performing repetitive tasks on large blocks of data than CPUs, you start see the benefit of enlisting a GPU in a server environment.

The Folding@home project and bitcoin mining are two of the most visible distributed computing projects that GPUs are accelerating, and they’re perfect examples of workloads made exponentially faster with the parallel processing power of graphics processing units. You don’t need to be folding protein or completing a blockchain to get the performance benefits, though; if you are taxing your CPUs with repetitive compute tasks, a GPU could make your life a lot easier.

If that still doesn’t make sense, I’ll turn the floor over to the Mythbusters in a presentation for our friends at NVIDIA:

SoftLayer uses NVIDIA Tesla GPUs in our high performance computing servers, so developers can use “Compute Unified Device Architecture” (CUDA) to easily take advantage of their GPU’s capabilities.

Hopefully, this quick rundown is helpful in demystifying the “technobabble” about GPUs and HPC … As a quick test, see if this sentence makes more sense now than it did when you started this blog: “If you want HPC to handle Gigaflops of computational operations, you probably need to supplement your server’s CPU and RAM with a GPU or two.”

Native Rank: Tech Partner Spotlight

By in Partner Marketplace, SoftLayer

This is a guest blog from Native Rank. Native Rank provides an effective solution for improving your visibility across search engines, social networks and web maps. They are a full-service search and advertising solution for small to large businesses both on a local and national level.

Ranking Well != Being Well Ranked

There is a common misconception in Search Engine Optimization: That if Company A was just on the first page for some random keyword, the sky would open up and leads would fall from the heavens. This is not always the case, and a better place to start the process of deciding what Key Words will be most effective for a client to rank for can be assessed in 3 easy steps:

  1. In depth keyword analysis for terms that your customers actually use to find a business like yours. If you specialize in DUI law, keywords structured around your area of expertise will lead to a higher quality of lead than the search term, “Denver Attorney.”
  2. Be realistic about who your competitors are and find where they are ranking organically. There is no need to reinvent the wheel. This will give you a good road map for what your competitors are doing and they are creating success.
  3. If you have a physical location make sure your local maps listings for Google, Yahoo and Bing are optimized and Owner Verified. The Search Engines want to show your business to Searchers that are in your Geographic area..Please let them!

Once you have gone through those three easy steps, make sure that the SEO company you are working with has the same expectations that you have for your business. Targeted success metrics and milestones need to be at the core of your SEO strategy. Ranking for 50 Keywords that bounce at 90% will not result in more customers through your door. It is very important that the SEO firm you use has your business objectives in mind. If not you may find yourselves three or six months down the road having a very uncomfortable conversation about what success is.

If you’ve never made a concerted effort into SEO and SEM strategy, we’d be happy to share some of the tools we’ve developed to get you ranking well whether you consider yourself a local business or a national one. Head over to http://nativerank.com/ to see a few of our products in action and learn a little more about our service.

Adding ‘Moore’ Storage Solutions

By in Executive Blog, Infrastructure, SoftLayer, Technology

In 1965, Intel co-founder Gordon Moore observed an interesting trend:”The complexity for minimum component costs has increased at a rate of roughly a factor of two per year … Certainly over the short term this rate can be expected to continue, if not to increase.”

Moore was initially noting the number of transistors that can be placed on an integrated circuit at a relatively constant minimal cost. Because that measure has proven so representative of the progress of our technological manufacturing abilities, “Moore’s Law” has become a cornerstone in discussions of pricing, capacity and speed of almost anything in the computer realm. You’ve probably heard the law used generically to refer to the constant improvements in technology: In two years, you can purchase twice as much capacity, speed, bandwidth or any other easily-measureable and relevant technology metric for the price you would pay today and for the current levels of production.

Think back to your first computer. How much storage capacity did it have? You were excited to be counting in bytes and kilobytes … “Look at all this space!” A few years later, you heard about people at NASA using “gigabytes” of space, and you were dumbfounded. Fastforward a few more years, and you wonder how long your 32GB flash drive will last before you need to upgrade the capacity.

32GB Thumb Drive

As manufacturers have found ways to build bigger and faster drives, users have found ways to fill them up. As a result of this behavior, we generally go from “being able to use” a certain capacity to “needing to use” that capacity. From a hosting provider perspective, we’ve seen the same trend from our customers … We’ll introduce new high-capacity hard drives, and within weeks, we’re getting calls about when we can double it. That’s why we’re always on the lookout for opportunities to incorporate product offerings that meet and (at least temporarily) exceed our customers’ needs.

Today, we announced Quantastor Storage Servers, dedicated mass storage appliances with exceptional cost-effectiveness, control and scalability. Built on SoftLayer Mass Storage dedicated servers with the OS NEXUS QuantaStor Storage Appliance OS, the solution supports up to 48TB of data with the perfect combination of performance economics, scalability and manageability. To give you a frame of reference, this is 48TB worth of hard drives:

48TB

If you’ve been looking for a fantastic, high-capacity storage solution, you should give our QuantaStor offering a spin. The SAN (iSCSI) + NAS (NFS) storage system delivers advanced storage features including, thin-provisioning, and remote-replication. These capabilities make it ideally suited for a broad set of applications including VM application deployments, virtual desktops, as well as web and application servers. From what I’ve seen, it’s at the top of the game right now, and it looks like it’s a perfect option for long-term reliability and scalability.

An Introduction to Redis

By in Development, Technology, Tips and Tricks

I recently had the opportunity to get re-acquainted with Redis while evaluating solutions for a project on the Product Innovation team here at SoftLayer. I’d actually played with it a couple of times before, but this time it “clicked.” Or my brain broke. Either way, I see a lot of potential for Redis now.

No one product is a perfect fit for all of your data storage needs, of course. There are such fundamental tradeoffs to be made in designing storage architectures that you should be immediately suspicious of any product that claims to fit every need.

The best solutions tend to be products that actually embrace these tradeoffs. Redis, for instance, has sacrificed a small amount of data durability in exchange for being awesome.

What is it?

Redis is a key/value store, but describing it that way is sort of like calling a helicopter a “vehicle.” It’s a technically correct description, but it leaves out some important stuff.

You can think of it like a sophisticated older brother of Memcached. It presents a flat keyspace, and you can set those keys to string values. Another feature of Memcached is the ability to perform remote atomic operations, like “incr” and “append.” These are really handy, because you have the ability to modify remote data without fetching, and you have an assurance that you’re the only one performing that operation at that instant.

Redis takes this concept of remote commands on data and goes completely nuts with it. The database is aware of data structures like hashes, lists and sets in addition to simple string values. You can sort, union, intersect, slice and dice to your heart’s content without fetching any data. Redis is a data structure server. You can treat it like remote memory, and this has an awesome immediate benefit for a programmer: your code and brain are already optimized for these data types.

But it’s not just about making storage simpler. It’s fast, too. Crazy fast. If you make intelligent use of its data structures, it’s possible to serve a lot of traffic from relatively modest hardware. Redis 2.4 can easily handle ~50k list appends a second on my notebook. With batching, it can append 2 million items to a list on a remote host in about 1.28 seconds.

It allows the remote, atomic and performant manipulation of data structures. It took me a little while to realize exactly how useful that is.

What’s wrong with it?

Nothing. Move along.

OK, it’s a little short on durability. Redis uses memory as its primary store and periodically flushes to disk. A common configuration is to do so every second.

That sounds pretty reasonable. If a server goes down, you could lose a second of data. Keep in mind, however, how many operations Redis can perform in a second. If you’re in a high-volume environment, that could be a lot of data. It’s not for your financial transactions.

It also supports relatively limited availability options. Currently, it only supports master/slave replication. Clustering support is planned for an upcoming release. It’s looking pretty powerful, but it will take some real-world testing to know its performance impact.

These challenges should be taken into consideration, and it’s probably clear if you’re in a situation where the current tradeoffs aren’t a good fit.

In my experience, a lot of developers seriously overestimate the consequences of their application losing small amounts of data. Also consider whether or not the chance of losing a second (or less) of data genuinely represents a bigger threat to your application than any other compromises you might have made.

The Challenges of Cloud Security Below 10,000 Feet

By in Business, Cloud, Technology

This guest blog was contributed by Wendy Nather, Research Director, Enterprise Security Practice at The 451 Group. Her post comes on the heels of the highly anticipated launch of StillSecure’s Cloud SMS, and it provides some great context for the importance of security in the cloud. For more information about Cloud SMS, visit www.stillsecure.com and follow the latest updates on StillSecure’s blog, The Security Samurai.

If you’re a large enterprise, you’re in pretty good shape for the cloud: you know what kind of security you want and need, you have security staff who can validate what you’re getting from the provider, and you can hold up your end of the deal – since it takes both customer and provider working together to build a complete security program. Most of the security providers out there are building for you, because that’s where the money is; and they’re eager to work on scaling up to meet the requirements for your big business. If you want custom security clauses in a contract, chances are, you’ll get them.

But at the other end of the scale there are the cloud customers I refer to as being “below the security poverty line.” These are the small shops (like your doctor’s medical practice) that may not have an IT staff at all. These small businesses tend to be very dependent on third party providers, and when it comes to security, they have no way to know what they need. Do they really need DLP, a web application firewall, single sign-on, log management, and all the premium security bells and whistles? Even if you gave them a free appliance or a dedicated firewall VM, they wouldn’t know what to do with it or have anyone to run it.

And when a small business has only a couple of servers in a decommissioned restroom*, the provider may be able to move them to their cloud, but it may not be able to scale a security solution down far enough to make it simple to run and cost-effective for either side. This is the great challenge today: to make cloud security both effective and affordable, both above and below 10,000 feet, no matter whether you’re flying a jumbo airliner or a Cessna.

The Art of the Apology

By in Funny

I wrote a blog but it got ixnayed by legal. (That should be funny because I am “legal.” At this time I shall choose to remain cryptic, but as God is my witness, I’ll publish that blog someday after X, Y, and Z happens). Now, where was I – ah, yes, a new and different blog.

Today, boys and girls, we shall talk about the art of the apology. Since we were little, we’ve been taught to say “sorry.” (Well, most of us, but maybe not he whose names starts with J and ends in O-N-E-S, but I digress again). “Little Johnny, say sorry to your sister for bonking her on the head.” And Little Johnny will usually say sorry to avoid your wrath, rather than actually being sorry for the head bonking. This is the first lesson in the art of the apology – make sure it is sincere and that you mean it. Otherwise, it is really better if you say nothing at all. Maybe wait until it can become sincere, and if it can never become sincere, go back to step one and don’t say anything at all. The Boy often gets in trouble for head bonkings and other various and sundry misdeeds committed upon The Girl. He gets sent to time-out and then is supposed to apologize to The Girl. More often than not The Boy gets extremely defiant and grunts out a “sor-ry” as belligerently as he can. This only serves to piss The Mommy off and gets The Boy in even more trouble. (Can I use that word?) The takeaway on this is that The Boy needs to say sorry like he means it, or not bother getting out of time-out until he can do so. Another example of an apology that is better left unsaid is the disingenuous-apology-that-is-really-not-an-apology apology. Example: “I’m sorry you are an idiot, but….” Go back to time-out!!

Often a simple, sincere heart-felt apology can go a long way towards diffusing a situation that might otherwise result in hurt feelings, anger, and bitterness or, in my world, lawsuits. Maybe a manager loses his/her cool with an employee in one of the many stressful situations we face on a daily basis. When the manager calms down, an apology may be the cure to a situation that might later spiral out of control and explode. Maybe you have two feuding employees – an apology by one or both parties may be all it takes to turn a situation that may have resulted in a termination or two into one in which the working relationship is restored. This might involve a situation with your co-worker, your friend, your spouse or a client. Many times what happens is that we want to be right, rather than do what’s right. A meaningful apology to a client might save a $30,000/month account, but dad gummit, you are right and the client is wrong and they are an idiot and you are not. All of that may be true, but is it worth it? Is it really, really worth it? Is it worth that account? Is it worth that friendship? Is it worth your job? Is it worth that marriage?

Here, let me practice: “Mike, I am sorry you are mean and that I implied your upbringing was nothing less than stellar…..” Alright, alright – I’ll keep practicing.

*Note: This blog was inspired by the esteemed labor and employment lawyer Michael Maslanka and one of his recent blogs at http://texaslawyer.typepad.com/work_matters/2009/10/rudeness-and-resulting-resentment-can-foster-cheating.html, which I forwarded to our managers for their digestion.
