Hi Chris,
I tried sending you and the Bioclusters mailing list the following email on
the 20th March, wondering did you receive it.

On the topic on low latency interconnects, how many of you are running your
clusters with such interconnets? Especially in the area of bioinformatics.
We are using quadrics on one IA32 cluster and Myrinet on IA32, IA64 and G5.
With occasional mpi jobs that uses these interconnects, I do not see other
jobs requiring it.
