[Wien] Questions in goto library on Itanium2

Hi, I reversed the order of the libraries when linking (-lgoto... -llapack_lapw) (might be relevant, as the goto libraries also contain some (though not all) lapack routines).
Do you get the same errors when using no optimization at all (-O0) ?
I remember there's some issue about a routine xerbla for the goto library (see website); did you check that?
Good luck,
Kevin Jorissen.

	Dear Wien2k Users,
	I met troubles when I ran wien2k using the (efc7.1 + goto library ) on
	Itanium2 processors. That is the wien2k is running well, but the results are
	incorrect.  E.g. for the demo case TiC, after 20 cycles the energy or the
	charge distance are still not convergent. In fact the results of the first
	cycle of TiC case are wrong, the results of the first cycle of TiC are as
	fellows (efc7.1 + goto library):
	ENE: -1789.755269   (the right one should be: -1784.12)
	FER:   0.52773           (the right one should be:  0.73)
	DIS:    0.4593901       (the right one should be: 0.857)
	Details of the supercomputer are: SGI Altix 3700 system with Intel Itanium2
	(1.3GHz) processors and Red Hat Linux operating system.
	The tested speeds for the benchmark case are as follows.
	efc7.1 + mkl6.0          : 298  sec
	efc7.1 + goto library   : 209  sec
	Wien2k results for (efc7.1 + mkl6.0) are correct, no problem. The compiling
	options for (efc7.1 + goto library) are as follows:
	O: -FR -mp -w -O2
	L: -L../SRC_lib -Vaxlib
	P: 'DParallel'
	R: -llapark_lapw -lgoto_it2-r0.9
	Is someone using the Itanium2 processor and goto library? Could you please
	tell me how to get the correct results?
	Best Regards,
	Shunli Shang
