As a successor of the packages BatchJobs and BatchExperiments, batchtools provides a parallel implementation of Map for high performance computing systems managed by schedulers like Slurm, Sun Grid Engine, OpenLava, TORQUE/OpenPBS, Load Sharing Facility (LSF) or Docker Swarm (see the Setup vignette).
The main features conclude:
- Convenience: All relevant batch system operations (submitting, listing, killing) are either handled internally or abstracted via simple R functions
- Portability: With a well-defined interface, the source is independent from the underlying batch system - prototype locally, deploy on any high performance cluster
- Reproducibility: Every computational part has an associated seed stored in a data base which ensures reproducibility even when the underlying batch system changes
- Abstraction: The code layers for algorithms, experiment definitions and execution are cleanly separated and allow to write readable and maintainable code to manage large scale computer experiments
Install the stable version from CRAN:
install.packages("batchtools")
For the development version, use devtools:
devtools::install_github("mllg/batchtools")
The development of BatchJobs and BatchExperiments is discontinued for the following reasons:
- Maintainability: The packages BatchJobs and BatchExperiments are tightly connected which makes maintenance difficult. Changes have to be synchronized and tested against the current CRAN versions for compatibility. Furthermore, BatchExperiments violates CRAN policies by calling internal functions of BatchJobs.
- Data base issues: Although we invested weeks to mitigate issues with locks of the SQLite data base or file system (staged queries, file system timeouts, ...),
BatchJobskept working unreliable on some systems with high latency or specific file systems. This madeBatchJobsunusable for many users.
BatchJobs and BatchExperiments will remain on CRAN, but new features are unlikely to be ported back. See this vignette for a comparison of the packages.
