Marvin, also known as Plasma is the third UNH supercomputer after Zaphod (2004-2012) and Trillian (2014-2020).

Marvin was acquired, like the others, with the help of the NSF/MRI program under grant number AGS-1919310.

Marvin is a Cray with following characteristics:

Cray CS500 cluster supercomputer
AMD Rome 7702 processors
24 nodes, each with two AMD Rome 64-core CPUs and 512GB of memory and one 240GB SSD for local storage
3072 compute cores
12.3 TB of memory
1 HDR IB 200GB switch with 40 ports
1 Mellanox 48-port GigE switch with four 10Gb SFP ports
ClusterStor L300N running the Lustre file system with 1,18 TB usable capacity
Bright, Slurm, Cray Programming Environment, Intel compliers, and View for ClusterStor
Pro Assist, 9x5, NBD for five years

Software:

Besides the modules, some other packages are installed on the head nodes: ffmpeg, mpv, xv, xpdf so far
If you need other packages, consider installing the rpm in tour private $HOME/local. That seems to work for smaller packages. Otherwise email ops@sr.unh.edu.
module load example for compiling a simple cc program:

    module load gcc/8.1.0
    module load craype-x86-rome
    module load craype-network-infiniband
    module load cray-libsci/20.03.1
    module load craype/2.6.4
    module load perftools-base/20.03.0
    module load cce/9.1.3
    module load PrgEnv-cray/1.0.6
    module load cray-impi/5

Acknowledgements: Every publication that reports results obtained with Marvin (even if Marvin only played a minimal role) must acknowledge the use with the following statement:

Computations were performed on Marvin, a Cray CS500 supercomputer at UNH supported by the NSF MRI program under grant AGS-1919310.

It is also required that the author send a note to mailto:Francois.Foucart@unh.edu with the bibliographic reference. This is eminently important for reporting to NSF.

Narrative for proposals: UNH operates Marvin, a CRAY CS500 supercomputer with 3.072 compute cores, 12.2 TB of memory, INFINIBAND interconnect fabric, and 1180 TB Lustre disk space. Marvin has a top speed of about 100 TeraFlops. Marvin runs the Cray Linux Environment (CLE) and its software stack consists of the GNU, AOCC, and CRAY compilers along with the typical libraries such as MPI and HDF. Marvin batch jobs are managed using Slurm. Marvin will be available for this project.
