Hello, I work on large matrices and found something interesting. For multiplication of matrices, the order has a huge influence on computing time when one of them is a sparse matrix. In the below example, M is a full matrix and A is a sparse matrix in a regular matrix class. A %*% M takes much more time than M %*% A; moreover, t(t(M) %*% t(A)) is much faster than A %*% M with same result. I

Dear all, I have a few points that I am unsure about using scan. I know that it is covered in the intro to R, and also has been discussed here: http://www.mail-archive.com/r-help at r-project.org/msg04869.html but nevertheless, I cannot get it to work. I have a potentially very large matrix that I need to read in (35MB). I am about to run it on a server with 16G of memory etc, so I hope it

I've just been trying to catch up with the posts already so figured I'd just start another thread as it seemed I would address things from multiple emails. I really need to get my sieve filter script updated to move the list emails into the proper folder now I guess :) We can play with the revision of the packaging during testing. One idea would be to use 3.0.1-0.YYYYMMDD for

Dear all, I am currently working on the calculation of eigenvalues (and -vectors) of large matrices. Since these are mostly sparse matrices and I remember some specific functionalities in MATLAB for sparse matrices, I started a research how to optimize the calculation of eigenvalues of a sparse matrix. The function eigen itself works with the LAPACK library which has no special handling for

Attached patch makes the balloon driver arch-neutral (compiles on ia64... look ma, no #ifdef''s!). Please apply to xen-unstable. One change should be eyeballed, line 257 in balloon.c, because phys_to_machine_mapping[pfn] is not identical to pfn_to_mfn (different by sign bit, should be OK?)

Does OpenSSH scp/sftp mode transfer sparse files correctly, i.e. are holes skipped and not transferred as chunks of 0 bytes? [1] We're asking about sparse files in the >= 1PB range, which consists of multi-TB holes with around 600-2000GB of valid data. [1] Note the difference: Sparse files can have data sections which consist of valid 0 bytes. Holes in sparse files represent regions where

Hi, I'm very new to working with sparse matrices and would like to know how I can column permute a sparse matrix. Here is a small example: > M1 <- > spMatrix(nrow=5,ncol=6,i=sample(5,15,replace=TRUE),j=sample(6,15,replace=TRUE),x=round_any(rnorm(15,2),0.001)) > M1 5 x 6 sparse Matrix of class "dgTMatrix" [1,] 2.983 . 1.656 5.003 . .

Hi Xavi At this time I'm using 'plain' bricks with XFS. I'll be moving to LVM cached bricks. There is no RAID for data bricks, but I'll be using hardware RAID10 for SSD cache disks (I can use 'writeback' cache in this case). 'small file performance' is the main reason I'm looking at different options, i.e. using formated sparse files. I spent considerable

Have you done any testing with replica 2/3? IIRC my replica 2/3 tests out performed EC on smallfile workloads, it may be worth looking into if you can't get EC up to where you need it to be. -b ----- Original Message ----- > From: "Dmitri Chebotarov" <4dimach at gmail.com> > Cc: "gluster-users" <Gluster-users at gluster.org> > Sent: Tuesday,
