too many swap files & struggles on EC2 Linux

I have a 6GB PSB file, trying to make multi resolution tiles on a EC2 linux box, below are the specs...
  • 64 bit
  • Ubnutu
  • 16GB RAM
  • Configured a 200GB mount as /tmp -- for temp file storage, all the kro's are going here
  • kmakemultires -- is on another mount /data -- that has around 50GB of disk space
It fails at...

different stages, sometimes at creating tiles at Level 7 / 6.
I observe...
  • Around 1100 swap files created, is that fine? on the disk
  • It does not seem to use swap memory configured on 'free -m' show used as 0
  • kmakemultires is using almost 15GB of RAM
Questions...
  • Is there a better way for us to configure?
  • Has anybody tried on EC2 & working?
Appreciate all the help forum can share...

Hi,

the krpano tools have its own system-independent internal swapping system.

The swapped files will be written to this path:
http://krpano.com/tools/kmakemultires/config/#tempdir

Additionally when images will be converted to cubical, the 'temporary' cube images will be written here:
http://krpano.com/tools/kmakemultires/config/#tempcubepath

At these paths always enough disk-space should be free - when the writing there is failing, the tools will stop with a fatal-error.

Best regards,
Klaus
