ManeFrame I's documentation can be found here.


SMU’s new high-performance compute cluster will dramatically increase the computational capacity and performance that SMU provides to its researchers. The new cluster features state of the art CPUs, accelerators, and networking technologies, significantly more memory per node, and advanced interactive GPU-accelerated remote desktop experiences. Also, the cluster is much more energy efficient making it more economical to run and more environmentally friendly!

The new cluster will provide a similar interactive experience for researchers currently using ManeFrame. Similarities include the CentOS 7 operating system (replacing Scientific Linux 6; both are Red Hat Enterprise Linux derivatives), the SLURM resource scheduler, and the Lmod environment module system. Additionally, updated, but familiar, development tool chains will be available including the GCC, Intel, and PGI compiler suites. Optimized high-level programming environments such as MATLAB, Python, and R will also be installed in addition to the domain specific software packages that SMU researchers depend on for their work.

Standard-, Medium-, and High- Memory Compute Nodes

Each of the 176 standard compute nodes has 36 cores, 256 GB of memory, and 100 Gb/s networking. Specifically, these nodes contain dual Intel Xeon E5-2695v4 2.1 GHz 18-core “Broadwell” processors with 45 MB of cache each and 256 GB of DDR4-2400 memory. The “Broadwell” microarchitecture of these processors is four generations newer than the “Nehalem”-based Xeon processors in ManeFrame. This translates to more efficient execution per processor cycle and significantly improved vectorization via the second-generation Advanced Vector Extensions (AVX2). In addition, there are 35 medium- and five high-memory compute nodes which have the same processors, but feature 768 GB and 1,536 GB (1.5 TB) of DDR4-2400 memory respectively and ManeFrame’s new four 768 GB and six 1,536 GB (1.5 TB) nodes also will be added to the new cluster. The new and more efficient architecture, high core count, and high memory capacities of these nodes will provide significant improvements to existing computationally or memory intensive workflows.

Accelerator Nodes with NVIDIA GPUs

The 36 accelerator nodes with NVIDIA GPUs are configured with dual Intel Xeon E5-2695v4 2.1 GHz 18-core “Broadwell” processors, 256 GB of DDR4-2400 memory, and one NVIDIA P100 GPU accelerator. Each NVIDIA P100 GPU has 3584 CUDA cores and 16 GB CoWoS HBM2 memory. The P100 GPU is the based on the new Pascal architecture and an extremely high bandwidth (732 GB/s) stacked memory architecture. These GPUs, combined with an ever-broadening set of drop-in replacement libraries and ever easier to implement CUDA-based programming environments, make GPU-based acceleration significantly more approachable for many computationally intensive applications.

Many-Core Nodes with Intel Xeon Phi Processors

The 36 many-core nodes are configured with Intel Xeon Phi 7230 (also known as Knights Landing or KNL) processors and 385 GB of DDR4-2400 memory. Each Xeon Phi has 64 1.30 GHz cores and 16 GB of high bandwidth (400 GB/s) stacked memory. KNL processors are based on the Intel’s “Silvermont” Atom processor cores and have hardware-based support for up to four concurrent threads. A principal benefit of the KNL processors is that they are based on and binary compatible with x86 architectures and therefore do not require specialized programming languages or directives/pragmas.

Virtual Desktop Nodes

The five virtual desktop nodes will allow researchers remote desktop access to high-performance compute capability. These nodes can be used for applications that have demanding remote visualization and/or rendering requirements. In addition, these virtual desktops can be configured as either Linux or Windows for a handful of compatible applications. Each node has dual Intel Xeon E5-2695v4 2.1 GHz 18-core “Broadwell” processors, 256 GB of DDR4-2400 memory, and one NVIDIA Quadro M5000 GPU.

High-Performance Network

The cluster provides high-speed and low-latency EDR InfiniBand networking. Every node is equipped with a Mellanox ConnectX-5 InfiniBand adaptor and all nodes are connected via Mellanox Switch-IB 2 switches. The InfiniBand network provides 100 Gb/s and less than 600 nanosecond latency. Additionally, the combination of ConnectX-5 and Switch-IB 2 provides network acceleration for applications by off-loading some MPI calls, thereby reducing the load on the processors, freeing them to work on other computations.

High-Performance and Archival Storage

The cluster has three new storage systems. The first storage system will be an NFS based storage providing space for home directories, applications, libraries, and compilers, etc. This storage system provides 11.4 TB of sold state drive based usable space and 38.4 TB of usable 7200 RPM SAS storage space. This storage space will have an automatic retention of 30 days’ worth of changes. The second storage system will provide the high-performance Lustre file system for calculation scratch space. This storage system provides 2.8 PB of usable space with a write performance of 56.4 GB/s and read performance of 70.8 GB/s, when used in parallel. The third storage system is 110 TB of usable disk based archive space that includes off-site backup for disaster recovery.
