Hi! I would need an advice from those that use IB (as admins :) ) i have a choice between : 1. Mellanox InfiniHost? III Lx HCA card, single-port CX4, DDR, PCIe x8, mem-free, tall bracket, RoHS R5 2. QLogic Single Port 20 Gb InfiniBand to x16 PCI Express Adapter (Single Pack) aside the price is there anything else that could help me make a discrimination between this two? (these will be used in twin servers for a small (...

Hello everybody, I'm trying to build a function to illustrate, in 2D, the sequence of the "Single Link" algorithm (the purpose is merely didactic). The idea is to have the scatter of points on a graph. Iteratively, build the segments (with the "segments()" function, for each step). I simulated a data set "d", and created an object "r" using the

Hello, I going to try to install OFED 1.4 on Xen 3.3 and I`d like to realize a VMM kernel bypass. Thanks to it my doomU will be able to communicate directly with my HCA and not pass by the dom 0. How can I realize that ? Is there a soft or something like that to do the kernel by pass ? I saw that it exist things like XEN-IB driver and SoftIB, there can i get it ? Or is VMM kernel bypass included in Xen 3.3 ? regards Anthony _____________________________...

I'm pleased to announce that the ChemoSpec package is available on CRAN for the first time (as version 1.46-4). ChemoSpec is a collection of functions for plotting spectra (NMR, IR etc) and carrying out various forms of top-down exploratory data analysis, such as HCA, PCA and model-based clustering. The design permits comparison of data from samples which fall into groups such as treatment vs. control. Robust methods appropriate for this type of high-dimensional data are available. ChemoSpec is designed to be very user friendly and suitable for people w...

Hi there, is it possible in r to use the Initial partition established by using the HAC partition with the kmean clustering? E.g. perform the HCA, write the cluster affiliation in a seperate column > DF$hclus.label <- assignCluster(model.matrix(~-1 + A15 + B12 + C70 + E14 + + H61 + N56 + P48 + T69 + W32 + Y43, DF), DF, cutree(HClust.1, k = 3) -> use this as initial partition in the Kmeans I have checked several tuts and formu...

Hi folks! This is sort of OT but I thought maybe someone had a tip for me. What I'm looking for is a tool that I can install on two computer for example, put one on each side of the customers WAN and "try" the connection - simulalate x calls (using codec xxx) and get statistics out of it (delays, jitter, dropped packets and that sort of things).
