- 17:11, 16 August 2023 Dmitri talk contribs created page How to run an interactive job on ARC (Created page with "= Background = Running jobs is the main and the only way to run computations on ARC. Normally, a user creates a '''job script''' and submit it to SLURM on ARC using the <code>sbatch</code> command to run a computation. The '''login node''', ARC's gateway, is only intended to do '''management work''', such as * data management, * software management, and * job management. The '''login node''' could also be used to '''software development''', if you write scripts, or i...")
- 20:29, 14 July 2023 Dmitri talk contribs created page How to find nodenames allocated by SLURM for a job (Created page with "= Background = When a distributed job that is planned to run on multiple nodes requests several compute nodes from SLURM the program that is going to perform the computations needs to know the names of the compute nodes which are allocated to the job by SLURM to use those nodes. If the program is based on the distributed MPI library then the distribution of the computational processed to the nodes is done by the MPI program launcher, <code>mpirun</code> or <code>mpiexe...")

It features a wide variety of standard quantum chemical methods ranging from semiempirical methods to DFT to single- and multireference correlated ab initio methods. It can also treat environmental and relativistic effects. == Licensing == If you wish to use prebuilt ORCA executables: # You ha...")
- 17:49, 1 March 2023 Dmitri talk contribs created page How to request GPUs for batch jobs on ARC (Created page with "= GPUs on ARC = Currently, there are three partitions on ARC that have usable CUDA GPUs, '''gpu-v100''', '''gpu-a100''', and '''bigmem'''. ARC's configuration keeps changing depending on addition of new hardware and retiring of the old hardware, so you have to check available hardware on ARC before starting a new set of computations. * First, check the available partitions with GPUs on ARC following this article: : How to find available partitions on ARC. * Then,...")

- 22:39, 19 January 2023 Dmitri talk contribs created page How to find available partitions on ARC (Created page with "ARC is a relatively large and very heterogeneous cluster. It has lots of compute nodes and some of these nodes are very different in their hardware specifications and performance capabilities. On ARC, nodes with similar specifications are grouped into SLURM partitions. To use ARC effectively and to its full potential it is important that the researchers who use ARC can find available partitions and see important features of the nodes in those partitions. For this pur...")
