Question

forcing files to stay in RAM

Asked by: tanc24

Hi,

I run some calculations  updating some images ( updating each byte in them).
The total size of files is around 10-20 Mb.
At this point the finished programs loop (thousands of times) through open,read , update, save on hard cycle.

In order to not rewrite the programs and still making them run faster I was wondering if it is possible to keep the files in ram (saving the disk I/O could be more than enough)

I tried allready to have them in /tmp... I am not very sure they are really in ram... Is there any
 way to force those files to stay in the ram ( a kind of virtual disk) and my programs to see them as  regular files?  I guess tmpfs and mount sound like what I need, I would appreciate any hint,

 Thanks
