[Llvm-bgq-discuss] Performance Tools?

[Dan Schatzberg]

Hi Hal and Jeff,

I am trying to determine where the bottlenecks in my software is and
my preference is towards the tools which instrument my application to
gather performance data. I tried TAU and Scalasca but it seems that
Scalasca requires the IBM compilers to work and the TAU installation
on Cetus/Mira is only configured for gcc/ibm compilers. I was in the
process of configuring it myself when the systems went down for
maintenance today. I figured I would ask and see if anyone had any
recommendations. Thanks
