System requirements

See Limitations on maximum number of cores for information pertaining to working on systems with >64 cores.

Memory and CPU settings for mapping reads

For mapping reads to the human genome ( 3.2 gigabases), or genomes of a similar size, 16 GB RAM is required. Smaller systems can be used when mapping to small genomes.

Larger amounts of memory can help the overall speed of the analysis when working with large datasets, but little gain is expected above about 32 GB of RAM.

Increasing the number of cpus can decrease the time a read mapping takes, however performance gain is expected to be limited above approximately 40 threads.

System requirements for de novo assembly

De novo assembly may need more memory than stated above - this depends both on the number of reads, error profile and the complexity and size of the genome.

For examples of the memory usage of various data sets when using the De Novo Assembly tool, see https://resources.qiagenbioinformatics.com/white-papers/White_paper_on_de_novo_assembly_4.pdf.

System requirements for 3D viewers

A graphics card that supports OpenGL 2.0.

Note: 3D rendering is only supported when the CLC Genomics Workbench is installed on the same machine the viewer is opened on. Indirect rendering (such as X11 forwarding through ssh), remote desktop connection/VNC, and running in virtual machines is not supported.

CLC data location requirements

Requirements for CLC data locations are provided in Adding locations.
