Re: [ccp4bb]: Some naive questions about AltiVec

I'd like to share the following information that I was forwarded by a
contact at Apple. It doesn't address the problems people have
mentioned here regarding the Absoft and VAST compilers/optimizers,
but the link to CHUD tools (http://developer.apple.com/hardware/ve)
for assessing performance may be helpful to some.
**********
Apple provides profiling tools and information on how to optimize for
AltiVec. Check out, developer.apple.com/hardware/ve. Particularly check
out the CHUD tools that we provide. In addition we have a profiler for
OpenGL optimization. Check out the OpenGL pages. NAG fortran compilers
are now available for Mac OS X as are optimizers like VAST-F
http://www.psrv.com/altivecf.html. Absoft's Fortran compiler also provides
optimization assistance.
