Performance question I am using AutoNHITS and passing cpus=3

Question

Performance question I am using AutoNHITS and passing cpus=32 but when I look at the Ray s dashboard I only see one core maxed out at 100 while 31 cores are sitting idle Has anyone seen issues with parallel processing My versions are neuralforecast==1 3 0 amp ray==2 2 0 and this is running on AWS EC2 with Amazon Linux

Can you try with cpus=1 In tune its the opposite this is how much to reserve for each process I believe that pl lightning then limits the usage to 1 per process

Cristian (Nixtla) · Answer

We recommend to use GPUs On this data training 1 nbeats nhits model should take less than a minute with a single GPU You can therefore try many configurations `num samples` in a short period of time We usually use small AWS instances with 1 GPU such as the g3 4xlarge

Thanks I did cpus=1 and I see it s running in parallel now It s still not using all the cores but that s probably due to other settings and how much the algorithm decides it needs I ll have to see if we have access to GPU instances but that is a good advice
