Hi there, 

I'm trying to run BEAST v2.6.3 on GPU (Tesla V100s) but I'm having some issues. What I'm submitting:

module load gcc/6.2.0 cuda/10.1

~/sw/beast/bin/beast -beagle_GPU -beagle_double my_file.xml

But my output gives me this:

  Using BEAGLE version: 3.2.0 (PRE-RELEASE) resource 0: CPU

    with instance flags:  PRECISION_DOUBLE COMPUTATION_SYNCH EIGEN_REAL SCALING_MANUAL SCALERS_RAW VECTOR_SSE THREADING_NONE PROCESSOR_CPU FRAMEWORK_CPU

Does anyone know why my run is using CPU instead of GPU? Also wondering if there is any advantage to using multiple cores on GPU if I only have one large partition. 

Thanks,

Nicoletta

Miller, Mark

Hi Nicoletta,


I cant help with why it isn’t using gpus, but here is how we configure cpu/gpu runs on our machne:

GPUs give the best speedup for 1 partition data sets when there are lots of patterns.
