Re^3: System call doesn't work when there is a large amount of data in a hash

[1nickt]

Hi,

" I need these large hashes to store genetic data in a hash"

That's a bit like saying " I need these hashes because I need these hashes."

See:

• How do I post a question effectively?
• I know what I mean. Why don't you?

• XY Problem

Does your "genome assembly tool" accept Perl data hashes as input? Of course it does not. Therefore you must be somehow serializing your massive input to the program in your system call. Perhaps you need to write a file, or provide a data stream to a server? As noted by my learned colleague swampyankee, it's hard to conceive of why you need to store 250Gb of data in an in-memory hash. There are myriad techniques to avoid doing so, depending on your context; why don't you explain a bit more about that, and show some code?

Hope this helps!
