We copied the virtio_iommu_config from the virtio-iommu specification, which declares the fields using little-endian annotations (for example le32).

Dear all, I've been getting different results from the sparse and dense version of model.Matrix when used with sparse contrasts and interactions between factors. The same happens when using model.matrix and sparse.model.matrix. When calculating list.contrasts I get the same results for sparse and dense contrasts (except the type of the matrix is different of...

It seems to me that it should be possible to make --inplace and --sparse compatible. The manpage says -S, --sparse ... Conflicts with --inplace because it's not possible to overwrite data in a sparse fashion. but I think it _is_ possible to do that, provided the receiving side opens the dest file read-write instead of write-only. When w...

Hi. I have an old Xen para virt vm which I created using sparse file. Is there any way to convert this vm image to non-sparse without shutting down the vm?. Thanks Paras.

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 sparse matrices, same for the EIS...

In some filesystems, typically optimized for large I/O throughputs (like IBM GPFS, IBM SAN FS, or distributed filesystems in general) a lot of lseek() operations can strongly impact on performances. In this cases it can be helpful to enlarge the block size used to handle sparse files directly from a command line parameter. For example, using a sparse write size of 32KB, I've been able to increase the transfer rate of an order of magnitude copying the output files of scientific applications from GPFS to GPFS or GPFS to SAN FS. -Andrea --- Allow to change the block s...

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,] 2.9...

Hello, I am working with a sparse matrix that is approx. 13,900 by 14,100. My goal is to select a row out of the matrix and create a new matrix with that row repeated 13,900 times without having to do any looping. Example: Starting Matrix: exampleMatrix 3 x 4 sparse Matrix of class "dgCMatrix" [1,] 1 . . . [2,] . 1 ....

To whom it may concern, I am trying to maximize a log-likelihood function using optim. This is a simple problem with only 18 parameters. To conserve memory, I am using sparse matrices (SLAM) for some of the data matrices used in the computation of the likelihood. However, optim appears to convert the sparse matrix back to regular data format. This causes me to run out of memory as R tries to create an 8GB matrix. In short, it does not look as though "optim"...
