Hi Tobias, could we use information about memory accesses of a SCoP statement and def-use chains to determine statements, which don’t contain matrix multiplication of the following form? for (int i = 0; i < Upper Bound1; i++) for (int j = 0; j < Upper Bound2; j++) for (int k = 0; k < Upper Bound3; j++) C[i][j] += A[i][k] * B[k][j] We could probably check that memory access

Hi Tobias, according to [1], we can expect 90% of the turbo boost peak of the processor with a C version of Matrix-Matrix Multiplication that is similar to the one presented in [1]. In case of Intel Core i7-3820 SandyBridge, the theoretical maximal performance of the machine is 28.8 gflops and hence the expected number is 25,92 gflops. However, in case of, for example, n = m = 1056 and k = 1024

Hi Tobias, I think that we could split a patch that contains an implementation of tiling, interchanging and unrolling of specific loops into three separate patches: 1. The first one adds a class that describes a processor model. It also adds a new command line parameter that contains all necessary parameters of a target architecture, which are used to construct objects of the class. 2. The

I would appreciate * guidance regarding translation of IDL routines to R, generally * assistance translating two IDL routines to R, specifically Why I ask: I'm slowly learning how to do atmospheric modeling. One language that has been been popular in this space is IDL http://en.wikipedia.org/wiki/IDL_(programming_language) which unfortunately is proprietary (not to mention butt-ugly, IMHO

Hopefully someone can help with a bit of lighttpd configuration for my production rails app in Mac OS X. I have an application which will be accessed by many different domains and IP addresses. Examples: http://crm.local/ http://localhost/ http://192.168.0.49/ http://65.256.120.90/ (fake, but you get the idea, an external Internet facing IP address) http://crm.mydomain.net/

host static anyterm content locally, url parameterize anyterm rows/cols/general param update spec/makefile Ideally I wanted and tried hard to put all this into a seperate ovirt-server--anyterm subpackage, but we cannot 'reopen' the ovirt server virtual host defined in ovirt-server.conf to add the neccessary rewrite rules. it would be nice to figure out a way to do this ---

I would like to randomly shuffle a distance object, such as the one created by ade4{dist.binary} below. My first attempt, using sample(jc.dist) creates a shuffled vector, losing the lower triangular structure of the distance object. How can I Ishuffle the lower triangular part of a distance matrix without losing the structure? Thanks. --Dale x1 <- c(rep(0,4),1) x2 <- c(rep(0,2),rep(1,3))

I'm running an LSODA to generate some graphs, but I need to stop at a certain point and use those values to generate another LSODA output. This is working fine, but when I try to run the second LSODA, I get the "Error in eval(expr, envir, enclos) : object 'N' not found". Any ideas what can be causing this? I have no object 'N' anywhere in the script. I made an

Hello everybody, I have a question. I would like to get a correlation between constitutive and induced plant defence which I messured on 30 plant species. So I have table with Species, Induced defence (ID), and constitutive defence (CD). Since Induced and constitutive defence are not independant (so called spurious correlation) I should do a randomisation test. I have a syntax of my

Hi all, I use kriging to interpolate the precipitation from stations, but the map of this results show lots of stripes. (please see the attachment)I think there's something wrong with the setting of the dimension of this matrix, however, I have no idea how to know or test to see if this setting is correct or not.I've tried to switch the latitude and longitude, but still got the same
