Message 852788 - Posted: 12 Jan 2009, 23:58:40 UTC

A rather quiet weekend, though the astropulse validator seems to have gotten locked up on something. Josh and Eric and looking into that. This morning was a little weird. An old UPS we were using as a glorified power strip just up and stopped working, thus removing power to various sundry items in our secondary lab which wouldn't have been a big deal but one of those items was a switch, so sidious and vader (and casper for that matter) disappeared from the network for a short while there. Nobody seemed to notice. In the afternoon Jeff and I plotted some physical server moves for tomorrow's outage. We'll see how much we get done - and as always we take small steps with these big projects.

Various cuda-related items were discussed in our server meeting today. A bug that was causing the triplet overflows was found, and the blue screen of death issue with slower nVidia boards is getting a workaround. New client and application releases in the near future should clear some of this up.

Back to work - which means plotting lots of radar data for me.

Question, is the "triplet overflow" bug you mention the same as the problem with VLAR workunits crashing CUDA and possibly the video driver too?

No, they are two separate bugs - but Matt's post suggests that both are being addressed.

I thought that the VLAR bug affected all Nvidia cards regardless of the speed of the chip?

Definitely two different bugs. New app is going into beta shortly.

So the VLAR bug is going to be looked at after this next release?
