![]() ![]() For each compiler, there are numerous options and suboptions available. There are several compilers available on vc001, including ncc for C, nfort for Fortran, and nc++ for C++. opt/nec/ve/mpi/2.21.0/lib64/vh/intel (if intel is specified)ĭue to licensing restrictions, Vector Engine code can only be compiled on the Vector Engine Compiler node, vc001. opt/nec/ve/mpi/2.21.0/lib64/vh/gnu (if gnu is specified) The "version" parameter is a directory name in the following directory: Than those specified by RUNPATH embedded in a MPI programĮxecutable by the MPI compile command. Used at runtime in order to use VH MPI shared libraries other Necmpivars.sh can take additional parameters, however the opt/nec/ve/mpi/2.21.0/bin64/necmpivars.sh can be called with alternate parameters: I64 specify the default integer type is 64-bit opt/nec/ve/nlc/2.3.0/bin/nlcvars.sh can be called with alternate parameters: Sourcing: /opt/nec/ve/nlc/2.3.0/bin/nlcvars.sh The vector module version 2.8-1 is loaded. A brief explanation of the additional parameters is included in the output when loading the vector module. The module sources the scripts without any parameters. When the vector module is loaded, two shell scripts are sourced as part of the process: nlcvars.sh & necmpivars.sh Those scripts provide additional environment variable definitions and can be called with additional parameters, if needed. This command can also be included in your SBATCH script to ensure the proper environment variables are available for your job. This enables you to invoke the compiler and various other tools without having to specify the full path. $ sbatch my_ve_jobscript.slurmĪfter accessing a node in an interactive shell, you can load the NEC Vector module to update your PATH and other environment variables. $ srun -p amdvcompiler -n 1 -t 01:30:00 -pty bash ![]() ![]() This command will provide a bash shell on the Vector Compiler node: $ srun -p amdvector -n 1 -t 01:30:00 -pty bash This command will provide a bash shell on one of the Vector Engine nodes: You can use the following commands to get an interactive shell on one of the nodes. The AMD Vector nodes are accessed like any other node in the cluster. The jobs that run in this partition have a 3 day time limit and can be run on one of the VE nodes. amdvcompiler - Partition containing node vc001 that is used to compile VE code.There are two partitions that have been setup specifically for use with the Vector Engine nodes: The Arc HPC cluster contains over a dozen Slurm partitions, each representing a unique set of resources to help meet the scientific computing needs of our users. The Vector Engine nodes are named: v001 - v005 Vector Engine Card Memory Bandwidth: 1.53TB/s.Server node Cores: 2 x Physical AMD CPUs, each with 8 cores and hyperthreading, providing a total of 32 Cores.The Arc HPC environment includes 5 x AMD Compute Nodes each with a NEC Vector Engine Card, providing increased memory bandwidth and computational ability with increased power efficiency. Vector Engine Compute Nodes (v001 - v005) This node is licensed to enable users to compile code for the Vector Engine nodes.Īfter compiling your VE code, you can run your compiled programs any of the 5 x Vector Engine nodes. The ARC HPC environment includes 1 x VE Compiler node.
