https://community.intel.com/t5/Software-Archive/dfor-prefetch/m-p/933916#M15430 I thought dfor$prefetch as described in the 6.5 release notes might help performance of some code but I couldn't find any documentation on it. The compiler didn't like call dfor$prefetch(h(8*k+pflen)) where h is a 1-D complex(4) array so I tried call dfor$prefetch(%loc(h(8*k+pflen))) but got an internal compiler error. Does anybody know how to use this extension?

I'm not familiar with the details of using DFOR$PREFETCH.<BR /><BR />Steve Tue, 09 Jan 2001 01:30:38 GMT https://community.intel.com/t5/Software-Archive/dfor-prefetch/m-p/933917#M15431 Steven_L_Intel1 2001-01-09T01:30:38Z
