Health Monitoring
Hey, I am looking for healt monitoring software for my centos5.1 box. Nothing crazy (like nagios), just something that records memory/cpu usage every min to 5 mins. I added some vmware stuff and was looking to see when if swap gets used and cpu spikes. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Evan Thanks for the email. I had a look at gcc implementation of TBAA and I think three main steps in implementation of TBAA for LLVM will be this: April 20 ~ May 23: I will read gcc implementation in depth and play around with LLVM code. May 23 ~ July 6: Implementation and test of a simple version of TBAA that does not work with all aggregate types. I think part of the coding required for

Hi Ehsan, All of the projects you have listed are quite interesting. If I were to advocate for one, it would be #2. I think the scope of work is perfect for GSoc. I'd encourage send out a more concrete proposal when you're ready.
