Yes.  I just recompiled on the DEC 8400 with DEC f77
again, and reproduced the 27 GFlops.  I get much higher
numbers with a 100x100 matrix, but the dtime call
has a resolution of 1/60 sec, and at 625 MHz a 100x100
goes in less than 1/10 sec.

Kazushige Goto's address: <goto@statabo.rim.or.jp>

Kazushige, what is your policy for releasing and
distributing your code?
