Re: [Starpu-devel] Data movement per kernel

[Sameh Abdulah <sameh.abdulah@kaust.edu.sa>]

Dear Team,

 

We are working on a mixed precision project which mainly relies on the Cholesky factorization operation. We are facing a large data movement on distributed systems which we have realized using STARPU_COMM_STATS.

 

My question is: Is there any way to estimate the data movement cost per kernel? STARPU_COMM_STATS estimates the data movement cost per computing node which helped us to investigate the problem but not to understand the reason behind it.

 

 

Thanks,
