Good day all, I've got a question which relates to Valgrind though somewhat indirectly. As I develop software, I use valgrind to check its mental stability, this is great, however, as we all know Valgrind does impose a degree of overhead (entirely to be expected and not the concern of this email). My question is - given that at the moment it takes me 8 hours to validate one of 12 aspects of my software, what sort of hardware should I consider purchasing as a dedicated Valgrind machine? Would I be better off getting multiple CPUs per box or multiple boxes (I can spread the testing horizontally without problems, the testing actually is made up of 45,000+ data samples).

The latter, I should think... under Valgrind, everything runs single-threaded, more or less, even multithreaded programs, so having a multiprocessor machine is not much use. (Others might have more to say about this.) N |

Thanks, looks like I'll be heading for a blade setup then.... now, time to find the money to fund this :-D Regards. -- PLDaniels - Software - Xamime Unix systems Internet Development A.B.N. 19 500 721 806 PGP Public Key at http://www.pldaniels.com/gpg-keys.pld |
