& Rocket launch illustrationTech Launch

Welcome to Launch, the yearly Mines on-campus preview for incoming students.

In that spirit, Information & Technology Solutions  (I&TS), the campus IT department, presents Tech Launch — an overview of technology resources available to you at Mines.

Take a look at the information below, then navigate to our Getting Started Guide for even more details. Get a running start on the technology and computing part of your Mines experience.

I&TS welcomes you to Mines!

As a new student, you are granted access to a variety of Mines computing resources. This web page will tell you about many of those resources, including wireless networks, school email, free software, and even personal access to a supercomputer.

Of course, all these great computing resources are shared, so we want to say up front: With great power comes great responsibility. Take a look at Mines IT policies (www.mines.edu/policy-library/information-technology) and especially policies about the appropriate use of our shared resources.

But first, a few basic tips when getting started at Mines:

1. Passwords – don’t share them!
Password sharing is in violation of Mines policy. Worse, sharing your password can allow people to steal your identity. Who needs that kind of hassle your first semester here (or ever)?

2. Backups – do them! Now! Really!
You are responsible for backing up your own data and files. Your information is retained on Mines systems while you are an active student, but it can be lost or misplaced. Do yourself a favor and keep extra copies of important data for yourself on a USB flash drive or other device. And beware: After you leave Mines, any data, files, or email left behind will certainly be deleted. To get an early start on good backup strategies, see our backup FAQ: faqfinder.mines.edu/faq010.

3. Looking for a campus job? We have some.
I&TS hires students to help staff the Technology Support Center (TSC), in the northeast corner of the Center for Technology and Learning Media (CTLM) building. No prior experience is necessary, but it helps if you find computers highly entertaining. Check the Career Center (www.mines.edu/careers) DiggerNet listings for openings or drop by the Technology Support Center (CT156) to ask about joining our staff. This is a great way to gain work experience in the IT field while you’re still in school.

Again, welcome to Mines. And happy computing!

 

What services does CCIT provide?Information & Technology Solutions (I&TS) offers a wide variety of IT services to the Mines community. Here are a few select services that students may find particularly useful (in alphabetical order):

Cyber-Security Top 10 TipsThe security of your online information and accounts starts with you. Here are some best practices for avoiding identity theft or worse.

1. Never share your passwords with anyone, whether it’s your parents, girlfriend, boyfriend, BFF, soul-mate-for-life, random person who is totally fun to hang out with, Mines faculty or staff… anybody.

Passwords are your keys into the Mines systems where your identity resides. This includes essential personal information, your classes, your grades, your extracurricular activities, your GPA, your health records, and more. Keep it private. Do not use your Mines password for other services. I&TS will never ask you for your password.

2. Do not download or upload copyrighted files that have not been legally purchased or licensed. This includes (among other things) BitTorrent-sourced music, movies, TV shows, software, and ebooks. Such behavior always comes to the attention of Student Life in honoring the national Digital Millennium Copyright Act (DMCA) laws. Packaging malware as other kinds of content is a common way for criminals to take over your machine — you can sometimes be grabbing more than just an illegal copy of Game of Thrones!

3. Always run security software on your machines to give yourself greater protection. Windows users should activate Microsoft Defender (www.mines.edu/ccit/software-title/antivirus) or opt for a more full-featured program. Though macOS and Linux are attacked less-frequently, running an antivirus program on those devices is also wise, particularly if you share USB flash drives with others. Talk with our Technology Support Center (CT156) staff for recommendations about appropriate antivirus software.

4. Keep your machines up-to-date by ensuring that you have auto-updates enabled where possible. This does a good job in keeping your base operating system updated, along with your preferred web-browsers and any extensions you might use. Other packages – like iTunes, Microsoft Office, Adobe applications, and so on – have similar auto-update mechanisms. All should be enabled and used.

5. Remember that large portions of the web attempt to track your online behavior and sites you visit. Install appropriate browser plugins to block some of these attempts. For better online privacy, recommended browsing extensions — available for the major web-browsers — include: Disconnect, Privacy Badger, and HTTPS Anywhere (search for the appropriate extension from your preferred web browser). These extensions keep tracking companies from piecing together your online activities.

6. Re-evaluate your plugins occasionally. Make sure any external browser plugins you use are both truly needed and kept up-to-date. If you don’t regularly use a plugin, set it to “Ask to Activate” or just disable it, or even uninstall it, altogether. Problematic plug-ins include packages like Java, Adobe Flash Player, Adobe Acrobat Reader (or other external PDF viewer), and Microsoft’s Silverlight, among others.

7. When browsing email messages, instant messages, or other social-media postings, always apply common sense. If something seems odd (a “bank” has sent this message to me from an @gmail.com address) or too good to be true (is someone really wanting to send me $25 million?), it is almost certainly an attempt to trick you. Ignore the message, delete it, and move on.

This can also apply where someone you know sends you an unexpected link or attachment. Be cautious. Has this individual really sent this message or attachment to you, or has their email account been compromised by a scammer? Can you check with them via some other method of communication?

Any message that asks you to “reply instantly, otherwise your account will be deleted,” or requests your username or password, is certainly a scam! Malware is usually installed by opening attachments or links… so use your brain before clicking on links or attachments. Again, I&TS will never ask for your password. No other reputable company would either.

8. Be careful what you share via social media. Only post items that you truly would not mind sharing with anyone and everyone in the world. For more private exchanges, ensure your privacy settings are configured correctly. If that post you just made ends up in front of your parents, (soon-to-be former) friend, or future employer, is that okay? Items posted for everyone to see means that you could be sharing with identity thieves, who are extremely good at using and linking together all the information related to you. Identity theft is not something you want to deal with.

9. Be careful when using shared data sources, like physical USB sticks, portable hard drives, and other storage devices, including cloud storage. Always have your security software running to be able to scan, and perhaps block, access to suspicious files.

10. Don’t install random software on any of your computing devices. Only use known software that is from a known reputable source — otherwise, who knows what extra “goodies” you’ve just installed?!

The water to the compute resources is in a closed loop. The CDU has a heat exchanger with the heat emitted by the closed loop warming chilled water from central facilities. Remaining heat from the servers and heat generated by the other nodes is removed via two in-row coolers. The equipment list includes (2) APC ACRC301S In-Row Coolers and a MOTIVAIR Coolant Distribution Unit MCDU25


Mio.Mines.Edu
Your Supercomputer

You have access to a 120-plus Tflop HPC cluster for student and faculty research use.

Want to get started with supercomputing? Supercomputing is an increasingly important part of engineering and scientific research. Mines provides an advanced supercomputing cluster called “Mio” for the use of students and faculty who wish to take advantage of this extraordinary high-performance computing resource.

For students
Students have already purchased some access to Mio with Tech Fee funds—usable for general research, class projects, and learning HPC techniques. Students may also at times use Mio nodes purchased by their academic advisor or other professors. The HPC Group offers assistance to students (and faculty) to get up and running on Mio. Individual consultations and workshops are available.

For faculty
Mio holds many advantages for professors:

  • There’s no need to manage their own HPC resources
  • Professors can access other professors’ resources when allowed
  • Mines supplies high-quality Infiniband network infrastructure, which greatly improves the scalability of multinode applications
  • Cost is a reasonable $7,000 per node

Hardware description

  • 8 -28 compute cores per node
  • 2.4GHz – 3.06GHz
  • 24-256 GB/Node
  • Infiniband Interconnect
  • 2 GPU nodes – 7.23 Tflops
  • 240 TB parallel file system
  • 2 Power8 w/GPU nodes

What’s in a name?
The name “Mio” is a play on words. It is a Spanish translation of the word “mine,” as in “belongs to me.” The phrase “The computer is mine” can be translated as “El ordenador es mío.”



Mines’ Big Iron Supercomputer
154 Tflops 17.4Tbytes 10,496 Cores 85KW

AuN/MC2 is a unique machine, composed of two distinct compute platforms or partitions that share a common file system. Both platforms, as well as the file system, were purchased from IBM as a package. The common file system shared between the partitions can hold 480 TB. It has efficient support for parallel operation (that is, multiple cores accessing it at the same time). The two compute platforms are optimized for different purposes.

AuN

The smaller compute platform, in terms of capability, is AuN (“Golden”). It is a traditional HPC platform using standard Intel processors. It contains 144 compute nodes connected by a high-speed network. Each node contains 16 Intel SandyBridge compute cores and 64 GB of memory for a total 2,304 cores and 9,216 GB of memory. AuN is rated at 50 Tflops. It is housed in two double-wide racks with 72 nodes in each rack. AuN is designed to run jobs that require more memory per core.

Mc2

Mc2 (“Energy”) is an IBM BlueGene. Mc2 is housed in a single large 4’ x 4’ rack, currently half full with room for expansion. The BlueGene computer is designed from the ground up as an HPC platform. It has a very-high-speed network connecting the nodes so applications can scale well. Each node has a processor dedicated to systems operations in addition to the 16 cores that are available for users. The processors on Mc2 are IBM “Power” processors. Mc2 has 512 compute nodes, each with 16 GB of memory for a total core count of 8,912 user cores and 8,912 GB of memory. Mc2 is rated at 104 Tflops. The total power consumption of the system is about 85 kW with only 35 kW used by Mc2. Mc2 is water cooled. AuN currently runs with rear door heat exchangers but could run with air cooling only. BlueM is housed at the National Renewable Energy Laboratory, in Golden, CO. Mc2 is designed for jobs that can make use of a large number of cores.
