Hi,
Is there any documentation about the -D__USE_3D_FFT option within Quantum Espresso PWscf? I couldn't find any in the various manuals. In particular I'm interested to know whether this option is significant only for use with the internal FFT code provided with Quantum Espresso or also when using an external library for FFT (e.g. MKL). Any other information about the purpose/applicability/trade-offs involved in this option would also be very useful. Thanks, Paul. --- Paul Caheny Researcher Technical Computing Research Fujitsu Laboratories of Europe Ltd (FLE) phone: +44 (0) 20 8606 4529 e-mail: Paul.Caheny at uk.fujitsu.com<mailto:Paul.Caheny at uk.fujitsu.com> web: http://www.fujitsu.com/emea/about/fle/<http://www.fujitsu.com/emea/about/fle> ______________________________________________________________________ Fujitsu Laboratories of Europe Limited Hayes Park Central, Hayes End Road, Hayes, Middlesex, UB4 8FE Registered No. 4153469 This e-mail and any attachments are for the sole use of addressee(s) and may contain information which is privileged and confidential.
