How to use CUDA web apps
You can
access the project site through the link:
http://tesla.ce.pdn.ac.lk/cuda/
In the home
page you will find four options
They are:
1.
Matrix
Operations
2.
Mandelbrot
3.
Sorting
4.
Generating
Random Matrices
You could
able to do the above operations within a very short time with the parallel
programing used in this project.
Following
paragraphs will explain how to use the calculation methods available under the
above topics.
1. Matrix Operations
In “Matrix Operations”, there are
seven options available.
You
have to upload two matrix files (in .txt format) and give the
number of rows and number of columns. Then click, Send Request to get
the answer.
Here
also you have to upload two matrices (in .txt format). Here you
have to give the number of rows and number of columns to both matrices. Then click,
Send Request to get the answer.
Upload a square matrix (in .txt format) and
give number of rows/columns. Then click, Send Request to get the answer.
Here
you have to upload two files (in .txt format), one is square
matrix and other one is a vector(single column matrix)
with the same number of rows in the square matrix. Also, give the number of
rows in the matrices. Then click, Send Request to get the answer.
Upload
a square matrix (in .txt format) and give the number of rows.
Then click, Send Request to get the answer.
Upload
a square matrix (in .txt format) and give the number of rows.
Then click, Send Request to get the answer.
This
is the big and last part under matrix operations, here you can upload up to
five matrices and there you have to input number of columns and rows in each uploaded matrix.
In the
expression area, you have to provide an equation to operate on the matrices you
gave.
There
are some instructions available to you at the page itself also.

Expressions
can have +,,* operations including brackets.

Inverse
can be stated like inv (A) But nested inverses like inv (A*inv (B)) or inv () are not supported.

Spaces
are allowed. But not mandatory.

Up
to 5 matrices are supported. Keep unnecessary ones blank.
In “Mandelbrot”, you have to
give six inputs. They are:
1. Width
2. Height
3. Real Minimum
4. Real Maximum
5. Imaginary Minimum
6. Imaginary Maximum
Some example outputs of Mandelbrot
set:
In “Sorting”, you have to
upload one file containing a list and give the number of elements in the
list. Then click, Send Request to get the answer.
In “Random Matrix”, you have
to give the number of columns and number of rows. Then click, Send Request
to get the answer.

problems you encounter.
