Application Details

  • Description: Local accelerated base calling for Nanopore data.
  • Version: guppy 3.1.5 and 4.0.14
  • Modules: guppy/cpu/3.1.5 (CPU), guppy/gpu/3.1.5 (GPU), guppy/cpu/4.0.14 (CPU), guppy/gpu/4.0.14 (GPU), guppy/gpu/4.2.2
  • Licence: Free, open-source
  • Note: guppy version 3 will be removed from service soon

Usage Examples

Using the GPU as an accelerator will make the analysis considerably faster (on large data sets). For small runs, the CPU version is recommended and probably faster by removing the GPU overhead.

Important: guppy/gpu (GPU version) requires to compute level of six or above, see examples below.

Batch example

This uses 2 GPUs presently on GPU05 (compute level is high than 6) which is required by guppy's minimum requirement.

#!/bin/bash
#SBATCH -J guppy.job
#SBATCH --exclusive
#SBATCH -o gpu05.%j.out
#SBATCH -e gpu05.%j.err
#SBATCH -p gpu05
#SBATCH --gres=gpu:tesla:2
#SBATCH --exclusive

module purge
module load cuda/10.1.168
module load guppy/gpu/4.2.2

Compute capability

For applications that require this information:

  • K40m is 3.5
  • P100 is 6.0
