Thanks for the response Alexei, I'll look into it and report back in case anyone else is interested. Jon Agiato JonAgiato@nyc.rr.com ----- Original Message ----- From: "Alexei Novakov" To: Sent: Friday, November 22, 2002 5:26 PM Subject: Re: [Boost-Users] Re: uBLAS, MTL performance tests.

I know this is going to sound terribly naive, but how does one define DNDEBUG? I am using VS.NET and Borland Enterprise 6.0. Thanks!

add -DNDEBUG to command line arguments. Unfortunately I don't know where exactly you can edit command line arguments in VC.NET.

Thanks Joerg,

This is too much abstraction penalty for uBLAS.

Did you define - DNDEBUG

...

(enabling expression templates and disabling bounds and type checks)?

Oh yeah. NDEBUG really makes a difference. Now dense matrix performance rocks. I was confused a bit, cause usually special flag is used to compile debug version, not release one. But it works too as long as one knows about the trick.

I will test more with sparse matrices.

Regards.

Alexei.
