Re: [yt-users] Memory leaks and volume rendering

Thanks to everyone for the help. The files are not very big, so I think this is an issue of memory not being freed up as it should, as per Matt's suggestion. I'm rewriting the script as he suggested and then trying that. John On Jan 29, 2012, at 2:13 AM, Sam Skillman wrote:

Hi John,

Additionally, adding 'del cam, image' at the end of each loop should help considerably. The camera object contains the homogenized volume roughly equal to the size of the entire dataset for one field, so I'm guessing that is where most of it is coming from.

Let us know if that doesn't help.

I've found that calling the garbage collector via gc.collect() at the end of a loop over filenames fixes issues like this. Probably worth a try, anyway.

Hi all,

I'm volume rendering a ~1 GB dataset on an 8 CPU machine with 32 GB of RAM. I keep using up the memory on the machine with the following script, which creates a time series object and runs through the pfs to create each image. Is there other memory I should be freeing up at each iteration in the loop?
