I have a matrix of, say, M and N dimensions: my_matrix=matrix(c(1:60),nrow=6,ncol=10) I have two "id" vectors corresponding to the rows and columns, e.g.: id_m=seq(10,60,by=10) id_n=seq(100,1000,by=100) I would like to create a "proper" database (let's say a data.frame for this example -- i'm going to be loading these into an SQLite database, but we'll leave

Hi Rob & Mihai, I wrote vhost-nvme patches on top of Christoph's NVMe target. vhost-nvme still uses mmio. So the guest OS can run unmodified NVMe driver. But the tests I have done didn't show competitive performance compared to virtio-blk/virtio-scsi. The bottleneck is in mmio. Your nvme vendor extension patches reduces greatly the number of MMIO writes. So I'd like to push it

I'm creating a lattice barchart based off a pretty complicated data structure. The barchart comes out quite nice ( thanks to lattice ) but the problem is that the horizontal axis comes out all scrunched because the barchart doesn't know that the intervals of Var.1 are really "associated" with the conditioning variable Var.2. Therefore, all the intervals of Var.1 are put on

Hello, I noticed FUSE is not there by default disabled on centos 5. Is there a separate RPM that includes FUSE module for the same kernel as of centos 5 ?. I have installed the latest centos 5 update, don't see FUSE enabled . [root at xx]# pwd /lib/modules/2.6.18-8.1.8.el5/source [root at xx]# grep FUSE .config # CONFIG_FUSE_FS is not set [root at xx]# I checked both addons and

Hello, Just noticed a NFS panic on centos5 (no updates applied yet). I don't have the serial console attached yet to get the exact stack.
