Virtual screening with the GOLD Cluster Computing package
Our 2021.1 release allows high throughput docking with GOLD to be run with HPC clusters, giving you flexibility to perform virtual screens with cloud or cluster compute power.
This update allows you to apply the accurate, high-quality docking of GOLD at scale, with flexibility in deployment via high performance cluster (HPC).
Virtual screening with GOLD has been deployed in various studies, including this work looking for actives against COVID-19 Mpro – read the full story here.GOLD virtual screening requirements
- System requirements
- The cluster will need to have Singularity, Slurm and Python 3 (3.6 or later) installed. No extra Python modules are necessary.
- Please note that large virtual screens will require a lot of disk space for the input ligands. For instance, 100 million ligands downloaded from ZINC as gzipped SDF files takes 60 GB of disk space (the equivalent MOL2 files would be larger). The batching that is required for GOLD docking on the cluster (e.g. 50,000 batches of 2,000 ligands) would add an additional 100 GB (we use a lower level of compression for speed). Please make sure you have enough disk space for your job size. For large scale screens, we recommend use of the ‘MIN_OUT’ option to reduce the amount of output from GOLD.
- Installation or downloads needed:
- Download the GOLD Cluster Computing package (see link below) and extract it in a suitable location on the cluster.
- A CSD installation is not required on the system as GOLD is included inside the Singularity image (a SIF file) that is supplied with the package, but a suitable licence is required.
- Licence requirements
- You will need a CSD-Discovery licence to use the GOLD Cluster Computing package.
The GOLD Cluster product will be available for you to access at the following location /support-and-resources/downloads/ under CSD-Discovery->GOLD as ‘GOLD Cluster Computing’.
