Re: makefile question when adding a file to magmablas/ directory

It is interesting that dznrm2.cu is only included in the Makefile.src once but dnrm2.o, dznrm2.o, scnrm2.o and snnrm.o are in the magmablas/ directory. Am I required to have 4 variations of dstddev_mean.cu in magmablas/ directory? I tried cleanall and clean but I never get my magmablas/dstddev_mean....

Re: makefile question when adding a file to magmablas/ directory

I have my new file in Makefile.src but it never tries to compile. I think it needs to be configured somehow to know that it needs compiled. I placed my new file after dznrm2.cu in the Make.src: $(cdir)/dznrm2.cu \ $(cdir)/dstddev_mean.cu \ Do I need to configure? I tried the cmake approach but I get...

makefile question when adding a file to magmablas/ directory

I created a new file that I want compiled into the magmablas library. I tried adding my filename to Makefile.gen but then I noticed it said "AutoGenerated" . I also added it to CMake.src but my new file would make. I tried >> make cleanall but my file would never try to compile. I also tried creatin...

What is the best Linux distro for MAGMA 2.5

I am getting my hardware next week. P40 and a desktop! I will be installing my OS first.
What is the best Linux distro for MAGMA? RedhHat, CentOS, Ubuntu, Fedora, Debian? Does it really matter?

LU factorization numerical techniques

It is my understanding that a LU factorization numerically runs until the diagonal reaches values less than epsilon. I am not a math expert so correct me if I am wrong. Is there a way for me to get this epsilon? I am running my simulation on a cpu using a different library and I want the results to ...

statistics on a matrix's column

I have a 2000 x 400 (rows x cols) double precision floating point matrix. I want to find the sigma, and mean of each column using the GPU. Is this a good job for MAGMA? If so, what is a good approach? I am using MAGMA 2.5 on Linux. It seems that coalescing would be important.

Doing multiply matrix operations then send back answer to CPU

I have many matrix operations that I need to be done on the GPU prior to sending the find answer back to the CPU. What are your suggestions on performing this on the GPU without continuously communicating with the CPU? These are equations of motion using 130x130 dense matrices.             // A = M^...

Staying on GPU while working on a series of equations

I have several equations of motion (EOM) that I want to finish on the GPU before returning to the CPU.             // Block Matrix Inverse:             // A = M^-1*RHS             // A^T = |Arns Af| (separate rigid/nozzle/slosh from flex)             // RHS^T = |xrns xf|             // | A   B |^-1 ...
