IBSRM

Today, I fixed a bug with the OpenIB IPoIB implementation (this is the module that allows you to run an IP network on top of an Infiniband network). There was an issue with /proc file creation that was b0rking unloading of the module. Roland has been also actively fixing up ipoib and it is getting pretty good.

Also, I got a couple of Arbel cards in finally after a mixup with the first order. Arbel is a PCI Express Infiniband card. Since I needed to bring down my brinup system to install the card, it gave me a good opportunity to upgrade the Opteron's from 244s to 248s bringing them both from 1.8Ghz to 2.2Ghz. Q had already put the faster 3200 memory in there, so now I have a rocking machine for sure. With big, honking heat sings and fans on their, it looks pretty cool too. I should take a picture and put it up here...

The picture here is a graphical representation of the IB network. The big blue dot is a sleipner IB switch. The red ones are host nodes. Even though there is nothing indicating what is what, the one with the SM on it is a Sparc64/Solaris box running IBSRM (Sun's subnet manager). The other red dots are Linux systems with openib on them. One is an Opteron system. The other a Sparc64/Linux box as mentioned previously.
