DCSR

Dynamic CSR matrix

This is still a work in progress...

To build just type make, but Makefile will need to be edited to match the specs/local paths on your machine.

There are a few matrix files in .mtx format in the matrices folder.

Usage: ./DCSR matrixfile

//comments on usage The matrix format is compatible with existing formats. Typical usage will involve conversion from another format such as CSR, COO, HYB, etc. followed by updates to the matrix and then conversion back to the previous format. The code could also be written to use DCSR entirely.

dcsr's Issues

core dumped when add test

Hi,

I am quite interesting for your work, especially for the iterative part.

Well, I was wondering whether there are some kinds of limitation for the insertion?

I found that when I try to update a little more entries (say the slice number is set to 500 instead of 50 on matrices/cnr-2000.mtx dataset), the ADD TEST will core dumped on iter: 395.

iter: 395
terminate called after throwing an instance of 'thrust::system::system_error'
what(): cudaFree in free: an illegal memory access was encountered
Aborted (core dumped)

It seems preserved memory space exceed. I wanna know is it some limitation or a bug, or I did something wrong.

Here is everything I do:

1. set add_test on
2. set slice num to 500
3. fix the namespace error: DCSR/src/Fill_Test.inl line:228 remove "detail"

Thank you so much and waiting for your reply.
