AW: information about simulation speed

How many cores do you use along with the GPU?

What version of namd do you use, also build type (multicore/net…)?

What timestep do you use?

What fullelectfrequency do you use?

Have you tried “twoawayx yes”?

Look around for the apoa1 or stmv benchmark for which you will find data to compare yours against on the web.

Betreff: Re: namd-l: information about simulation speed

 

Hi,

 

I am using Nvidia GTX 680 gpu for namd (cuda version) run but simulation speed, as it shows 0.496354 days/ns (~2ns/day) while system has almost 54000 atoms including solvent. Isn't it very slow? Please suggest me to get proper benchmark.

 

Regards

Kshatresh

Grep around for a "Benchmark" line. They are there.

Yes, but I found like :

 

WallClock: 569.721008 CPUTime: 569.721008 Memory: 128.992188 MB,

 

Can we get information in simulation time like ns/day or ps/day?

have you looked at the NAMD output???
