Facilities, Equipment, and Other Resources
Coral Gables Campus
The University of Miami Institute for Data Science and Computing (IDSC) holds offices on the Coral Gables campus in the Gables One Tower and in the Ungar Building (N3 on map). Each location is equipped with dual processing workstations and essential software applications. IDSC has three dedicated conference rooms and communication technology to interact with advisors (telephone, web-, and video-conferencing), plus a Visualization Lab with 2D and 3D display walls. The University is powered by the vast resources of IDSC, which has an established, broad user base, and, a state-of-the-art research computing infrastructure.
NAP of the Americas
IDSC systems are co-located at the Century Link Data Center hosted by the Equinix NAP of the Americas (NOTA or “the NAP”). The NAP in Miami currently features a 750,000-square-foot, purpose-built data center Tier IV facility with N+2 14 Megawatt power and cooling infrastructure. The equipment floors start at 32 feet above sea level, and the roof slope was designed to aid in the drainage of floodwater in excess of 100-year-storm intensity, assisted by: 18 rooftop drains, architecture designed to withstand a Category 5 hurricane with approximately 19 million pounds of concrete roof ballast, and 7-inch-thick steel-reinforced concrete exterior panels. Plus, the building is outside FEMA’s 500-year designated flood zone. The NAP uses a dry pipe fire-suppression system to minimize the risk of damage from leaks.
The NAP features a centrally located Command Center manned by 24×7 security and security sensors. In order to connect the University with the NAP, UM has invested in a Dense Wavelength Division Multiplexing (DWDM) optical ring for all campuses. IDSC systems occupy a discrete, secure wavelength on the ring, which provides a distinct 10 Gigabit (GB) advanced computing network to all campuses and facilities.
Given the University’s past experiences (including several hurricanes and other natural disasters), we anticipate no service interruptions due to facilities issues. The NAP was designed and constructed for resilient operations. The University has gone through several hurricanes, power outages, and other severe weather crises without any loss of power or connectivity to the NAP. The NAP maintains its own generators with a flywheel power crossover system. This ensures that power is not interrupted when the switch is made to auxiliary power. The NAP maintains a two-week fuel supply (at 100% utilization) and is on the primary list for fuel replacement due to its importance as a data-serving facility.
In addition to hosting the University of Miami’s computing infrastructure, the NAP is home to the US SouthCOM, Amazon, EBay, and several telecommunications companies’ assets. The NAP at Miami hosts 97% of the network traffic between the US and Central/South America and is the local access point for Florida LambdaRail (FLR)—which is gated to Internet 2 (I2) to provide full support to the I2 Innovation Platform. The NAP also provides TLD information to the DNS infrastructure and is the local peering point for all networks in the area.
The University of Miami has made the NAP its primary Data Center occupying a very significant footprint. Currently, all IDSC resources, clusters, storage, and backup systems run from this facility, and serve all major campuses.
The University of Miami maintains one of the largest centralized academic cyberinfrastructures in the country with numerous assets. Since 2007, the core has grown from zero advanced computing cyberinfrastructure to a regional high-performance computing environment that currently supports more than 1,700 users, 240 TeraFLOPS (TFlops) of computational power, and more than 3 Petabytes (PB) of disk storage.
The University’s latest acquisition, “Triton,” is rated one of the Top 5 Academic Institution Supercomputers in the U.S. for 2019, and is UM’s first GPU-accelerated advanced computing system, representing a completely new approach to computational and data science for the University. Built using IBM Power Systems AC922 servers, this system was designed to maximize data movement between the IBM POWER9 CPU and attached accelerators like GPUs.

When “Pegasus” (the University’s first supercomputer) was launched, it ranked at number 389 on the November 2012 Top 500 Supercomputer Sites list. Pegasus is a 350-node Lenovo cluster with each node having 2 Intel Sandy Bridge E5-2670 (2.6 GHz) 8C—with 32 GB 1600 MHz RAM (2 GB/core) for a total of over 160 TFlops. Connected with an FDR Infiniband fabric, Pegasus was purpose-built for the style of data processing performed by biomedical research and analytics. In contrast with traditional supercomputers where data flows along the slowest communication network possible (Ethernet), Pegasus was built on the principle that data needs to be on the fastest fabric possible. By utilizing the low latency high bandwidth IB fabric for data, Pegasus was able to access all three tiers (SSD, 15K RPM SAS, 7.2K NL-SAS) at unprecedented speeds.
Unlike traditional advanced computing storage, the 150 TB /scratch filesystem is optimized for small random reads and writes; and can support over 125,000 sustained IOPs/second and 20 Gb/sec throughput at 4Kb file size. Composed of over 500 15K RPM SAS disks, /scratch is ideal for the extremely demanding IO requirements of biomedical workloads.
For instances where even /scratch is not fast enough, Pegasus has access to over 8TB of burst buffer space clocked at over 1,000,000 IOPs. This buffer space provides biomedical researchers a good place for large file manipulation and transformation.
Along with the 350 nodes in the general processing queue, all researchers also have access to the 20 large memory nodes in the bigmem queue. With access to the entire suite of software available on Pegasus, the bigmem queue provides large memory access (256 GB) to researchers where parallelization is not an option. With 20 cores each, the bigmem servers provide an SMP-like environment well suited to biomedical research.
As many modern analysis tools require interaction, Pegasus has a unique feature of allowing ssh and graphical (GUI) access to programs using LSF. Tools ranging from Matlab to Knime and SAS to R are available to researchers in the interactive queue with full-speed access to /scratch and the W.A.D.E. Storage Cloud.

W.A.D.E. Storage Cloud (Worldwide Advanced-Data Environment)
At the heart of the IDSC Advanced Computing data services is the W.A.D.E. Storage Cloud, which currently provides over 7 PB of active data to the University of Miami research community ranging from small spreadsheets in sports medicine research, to multi-TB, high-resolution image files, and NGS datasets. W.A.D.E. is composed of four DDN storage clusters running the GPFS filesystem. The combination of IBM’s industrial-strength filesystem and DDN’s high-performance hardware gives researchers at UM the flexibility to process data on Pegasus and share that data with anyone, anywhere.
By utilizing several file-service gateways, researchers can share large data sets securely between Mac, Windows, and Linux operating systems. Data can also be presented outside of the University in several high-performance ways. In addition to the common protocols of SCP and SFTP, we also provide high-speed parallel access through bbcp and Aspera. You can even share your data using standard web access (https) through our integrated web and cloud client service.
All-access to W.A.D.E. is provided through UM’s 10 GB/sec Research Network internally and the UM Science DMZ externally. All Internet traffic flows through either the Science DMZs 10 GB/Sec I2 link through Florida LambdaRail or through the Research Network’s 1 GB/sec commercial internet connect.

The AI + ML research group provides expertise and capabilities to further explore high-dimensional data. The following are examples of the expertise areas covered by our team:
- Classification appears essentially in every subject area that involves the collection of data of different types, such as disease diagnosis based on clinical and laboratory data. Methods include regression (linear and logistic), artificial neural nets (ANN), k-nearest neighborhood (KNN), support vector machines (SVM), Bayesian networks, decision trees, and others.
- Clustering is used to partition the input data points into mutually similar groupings, such that data points from different groups are not similar. Methods include KMeans, hierarchical clustering, and self-organizing map (SOM), and are often accompanied by space decomposition methods to offer low dimensional representations of high dimensional data space. Methods of space decomposition include principal component analysis (PCA), independent component analysis (IDA), multidimensional scaling (MDA), Isomap, and manifold learning. Advanced topics in clustering include multifold clustering, graphical models, and semi-supervised clustering.
- Association data mining finds frequent combinations of attributes in databases of categorical attributes. The frequent combinations can be then used to develop the prediction of categorical values.
- Analysis of sequential data involves mostly biological sequence and includes such diverse topics as the extraction of common patterns in genomic sequences for motif discovery, sequence comparison for haplotype analysis, alignment of sequences, and phylogeny reconstruction.
- Text mining, particularly in terms of extracting information from published papers, thus transforming documents to vectors of relatively low dimension to enable the use of data mining methods mentioned above.
