Hi Imre,

 

can you send me your config file too?

 

Kind regards,

Caren

Hi Owen,

 

We have not so nice solution as Tim has:

We have defined as many slots as many different use-case we expect:

We have 12 CPU cores  and 2 Tesla cards.

And we have defined start condition for all the supported use-cases.

(Singe CPU, multi CPU, single GPU+GPU, single GPU, etc.) The config file is quite complex, but it works. I can send it you, if you are interested in. (I don't want to pollute the list with it.)

 

Cheers,

 

Imre
