# Does the DRAGEN system process multiple samples in parallel?

**DRAGEN processes one sample at a time** using all the hardware resources available (FPGA + CPU) and does it as fast as possible vs sharing the resources to process multiple samples. This is true for on-site as well as cloud analysis.

Typically, the run times are so fast that running serially is not a problem for processing samples from a single instrument. For large-scale while genome sequencing (WGS) processing, with many high output sequencers, additional servers may be needed to keep up, or, it is possible to schedule many DRAGEN instances in parallel in the Cloud, where each instance processes 1 sample.
