Thunder run on GPU cluster: parameter, benchmark, scratch about thunder

[Zarrathustra]

1. For two nodes, we recommend putting two processes on the first node and one process on the second one.
2. Running speed depends on so much environment parameters, such as memory, GPUs, CPUs, network bandwidth, disk bandwidth. I am sorry that I can not give you an estimation. However, it is some benchmark tests in https://www.nature.com/articles/s41592-018-0223-8. Moreover, you can use https://github.com/thuem/THUNDER-demo-datasets as benchmarks. Download failure is due to lack of Github LFS service, https://git-lfs.github.com.
3. Sorry, currently, there is no local scratch support in THUNDER.
4. Currently, THUNDER will read all particles in physical memory. We are working the memory buffer system which will load particles into physical memory when needed. We hope to release this feature soon. A present solution to his "out of memory" issue is to use SWAP. By configuring SWAP to a larger partition, it will get this issue solved.

Best regards,

Thanks. Besides, could thunder support LFS cluster?

[Zarrathustra]

Sure.

In Tsinghua, we use LFS and SLURM as job manager.

If you have any problem with running THUNDER using LFS job manager, please contact us.
