Hi all, I am currently working with a quite large matrix that takes 300G of memory. My computer only has 512G of memory. I would need to do a few arithmetic on it with a scalar value. My current code looks like this: mat <- 100 - mat However such code quickly uses up all of the remaining memory and got the R script killed by OOM killer. Are there any more memory-efficient way of doing such operatio...

Currently I''m trying to figure out the best zfs layout for a thumper wrt. to read AND write performance. I did some simple mkfile 512G tests and found out, that per average ~ 500 MB/s seems to be the maximum on can reach (tried initial default setup, all 46 HDDs as R0, etc.). According to http://www.amd.com/us-en/assets/content_type/DownloadableAssets/ArchitectureWP_062806.pdf I would assume, that much more and at least in theor...

Hello, In http://wiki.xensource.com/xenwiki/Xen4.0 we mention the following: "Better performance and scalability: 128 vcpus per guest, 1 TB of RAM per host, 128 physical CPUs per host (as a default, can be compile-time increased to lots more)." But what''s the max supported amount of memory for a (64bit) guest? -- Pasi _______________________________________________

While adding code to create the compatibility p2m table mappings it seemed to me that the creation of the native ones is restricted to memory below the 512G boundary - otherwise, additional L2 tables would need to be allocated (currently other memory following the one L2 page getting allocated would be blindly overwritten). While I realize that machines this big aren''t likely to be targeted by Xen at this point anyway (although the direct map...

We have a zpool made of 4 512g iscsi luns located on a network appliance. We are seeing poor read performance from the zfs pool. The release of solaris we are using is: Solaris 10 10/09 s10s_u8wos_08a SPARC The server itself is a T2000 I was wondering how we can tell if the zfs_vdev_max_pending setting is impeding read perfor...

Hi I am setting up a phone system for a small office. The office will have 5-8 phones and a fax line. There are 4 hunt lines coming into the office. We have made no hardware purchase yet. Being an asterisk newbie, before I suscribed to this list I just assumed that I would buy voip phones and connect all the phones to a private ethernet network. However, I see many people inquiring about FXS
