Real Cost Comparison of Fat-tree and Torus Networks
Thanks to Mellanox Technologies, our tool that designs fat-tree and torus networks now operates with real life prices for InfiniBand hardware. Mellanox kindly provided list prices for the previous generation of switches, InfiniBand QDR: these figures are not likely to … Continue reading
How To Size Your UPS System: More Power, Igor!
We now have a tool to size UPS systems! Find it in the menu above, or use this link. (As for the headline, Igor is a character of Tom Holt’s novel, “Igor”)
Torus Network: As Round As It Gets
Fat-trees have great performance characteristics, but they can be costly for some installations. Blocking fat-trees can be used as an alternative, but if your computational task has locality of communications and is well suited to torus networks — why not … Continue reading

Electrochemical Power Supply and Water Cooling, In One Go
I was searching the IBM website to find info on their cooling system, Aquasar, in the hope to find a better way to learn about it rather than just looking at their hardware. And indeed, I found something new and … Continue reading
T-Platforms and Water Cooling
For ISC’11 in Hamburg, T-Platforms brought to their exhibition booth a prototype of a water-cooled system. I think I remember those thick black rubber tubes (and hope that was not a dream). (UPD: A Google search reveals that they were, … Continue reading
Poster on “Computer Cluster Design Automation Using Web Services”
I have just presented my new poster, “Computer Cluster Design Automation Using Web Services“, at the International Supercomputing Conference (ISC’12) in Hamburg. The poster session moved this year to the exhibition hall. If you were there but missed it, use … Continue reading

Lustre Strives to Go Mainstream
Do you remember Chroma, the software from Whamcloud that allows to deploy and manage Lustre installations with a web interface? In April 2012, DataDirect Networks (DDN) announced they have successfully integrated Chroma into their EXAScaler storage system. I believe it … Continue reading
Open Hardware Paves the Way to Commodity Water Cooled Servers
Google is making its own custom servers, but they don’t disclose many important details. On the contrary, Facebook is trying to provide as much information as possible about their own custom servers — in the hope it will benefit the … Continue reading
The Giants That Slowed Down
During the recent decades, the US was able to attract the best scientists from all over the world in every field, including computing, by providing them with competitive salaries and benefits. But now research budgets are being cut, and the … Continue reading
