maximum acceptable ram to run MaxEnt

[Iman Momeni]

Dear All
Does MaxEnt has any limitation regarding memory (RAM) usage?

[Iman Momeni]

Dear all
attached shows when I set Maxent to use 6gb of memory to speed up the processing, it only uses around 300k!
I'm in hurry. please help me to solve the problem.

In my case the ram has never been a "bottleneck" in the performance, but my cpu; maxent has a "Threads" option in the experimental tab of the settings, your cpu may have more than 1 "core", google how to know how many cores your pc have and that will be the number of threads you could say your Maxent to use, each extra trhead could improve the performance, arguably, up to 40%.

Excuse my bad English, but if you are in a hurry the info could be useful.

Dear Sancordar
Thank you for the answer. I'l try this. hope to decrease processing time. Does this method works on ENMeval also? Is it same as parallel in ENMeval?

HinImam,

It looks like you're running Windows. In 32-bit Windows you only get 2 GB per program, whereas in 64-bit Windows you get 3 Gb (assuming your computer has this much). So there is an upper limit to how much Maxent can use.

If memory is truly the limiting step, I am guessing it's because you're using big rasters. In this care the only thing you can do is increase cell size or crop the rasters.

Hi adam
Thank you for the answer. Do you know this limitation arises from java or maxent?
I find a guide that shows how to increase memory available for java(attached pic).

It's approximate 1gb ram unless you make setting else it will 500mb approx by default.

Thank you for the answer
So, it not depends on windows *64 or 32?

[Adam Smith]

The limitation is Windows' limitation--the same limit applies to other programs (Word, Excel, etc.).  You can try to increase memory beyond these limits, but Windows will still put a cap on the memory allowed.

thank you Adam
