Implemented metis-partitionned multi-GPU PDLP.
To run PDLP using multi-GPU run :
./cpp/build/cuopt_cli ../path/to/file.mps --method 1 --use-distributed-pdlp true --presolve 0, the exact number of GPUs used can be set with--distributed-pdlp-num-gpus nAll benchmarking results against D-PDLP and single GPU CuOpt can be found in this spreadsheet
Here is the bottom line of the results
On 8 NVLINKed B200 :
against CuOpt :
against D-PDLP
to note: the speedups against D-PDLP are computed with NVLS_SHARP=0 disabling a feature that could give them a speedup from 1.1x to 1.75x I am looking with the compute-lab team to make it work
