Re: [deal.II] Scaling behavior of Matrix-Free test program

Maxi, it would likely be interesting to run the STREAM benchmark on these two systems to see how much memory bandwidth you can hope to get. I would not be too surprised if that still is the limiting factor for your test. Best, Daniel Am Mo., 2. März 2020 um 12:17 Uhr schrieb 'Maxi Miller' via de

[deal.II] Scaling behavior of Matrix-Free test program

I wrote a small test program for solving a non-linear equation using the RK4-solver implemented in deal.II, and assembling the right hand side using the matrix-free framework (code is attached). Afterwards I wanted to check the scaling behavior, after it should serve as a base for a larger progr

Re: [deal.II] Step-57

Hussan, Do you observe this problem with the unmodified step-57 or did you change anything? What does the full backtrace look like (running gdb)? Best, Daniel Am Mo., 2. März 2020 um 09:42 Uhr schrieb hussan zeb : > how can resolve this error in step-57, > Scanning dependencies of target step-5
