Dear ALL:
Recently when trying to do Abinit calculation, there is always a problem of Memory:
memana : ERROR -
Test failed to allocate 4285.261 Mbytes
Then in order to overcome this, I even bought 32Gb (4*8Gb) memory...
However, it still does not work, even 4 cores need 4285*4 <<32Gb.
Therefore, I was wondering, is this because the Abinit I installed is NOT a parallel version, which is 32bit and cannot understand memory >4Gb?
Thank you very much for any kind of help and suggestions.
Cheers!

Re: Difference ABINIT 7.0.5 and ABINIT 7.0.5 Parallel Versio [SOLVED]
32bit applications have address space limitations - in your case without entering too much in the details, 2GB or 4GB but no more than that.
The mention "not a parallel version which is 32bit" ... it's possible to build a 64bit sequential abinit executable as long as your operating system supports 64bit apps. I see mentions elsewhere that you compile on Windows; the following page http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778%28v=vs.85%29.aspx summaries these limitations.
Kind regards,
Alain
