Initial commit of Complex multiplication sample. Modified sample.Json to include citests and guid, updated readme and latest code sample (oneapi-src#10)
* Signed-off-by: praveenkk123 <[email protected]> adding complex multiplication sample to the repo * Updated Readme, and uploaded the complex multiplication example <[email protected]> * changed id from 'i' to 'idx', moved the dpc_common.hpp to common folder, changed the variable of custom_device_selector, updated year in the license file and changed the output format similar to vector-add * removed the local copy of dpc_common.hpp and using from the oneapi path and updated the source code to use it accordingly * fixed complex.hpp licensing

# Complex Multiplication sample
2+
3+
complex multiplication is a program that multiplies two large vectors of
4+
Complex numbers in parallel and verifies the results. It also implements
5+
custom device selector to target a specific vendor device. This program is
6+
implemented using C++ and DPC++ language for Intel CPU and accelerators.
7+
The Complex class is a custom class and this program shows how we can use
8+
custom types of classes in a DPC++ program
9+
10+
| Optimized for | Description
11+
|:--- |:---
12+
| OS | Linux Ubuntu 18.04, Windows 10
13+
| Hardware | Skylake with GEN9 or newer
14+
| Software | Intel&reg; oneAPI DPC++ Compiler (beta)
15+
| What you will learn | Using custom type classes and offloads complex number computations to GPU using Intel DPC++
16+
| Time to complete | 15 minutes
17+
18+
19+
## Purpose
20+
21+
Complex multiplication multiplies two vectors with complex numbers. The
22+
code will attempt to run the calculation on both the GPU and CPU, and then
23+
verifies the results. The size of the computation can be adjusted for
24+
heavier workloads. If successful, the name of the offload device and a
25+
success message are displayed.
26+
27+
This sample uses buffers to manage memory. For more information regarding
28+
different memory management options, refer to the vector_add sample.
29+
30+
complex multiplication includes C++ implementations of both Data Parallel
31+
(DPC++).
32+
33+
This program shows how to create a custom device selector and to target
34+
GPU or CPU of a specific vendor. The program also shows how to pass in a
35+
vector of custom Complex class objects that you can do the parallel
36+
executions on the device. The device used for compilation is displayed in
37+
the output.
38+
39+
40+
## Key implementation details
41+
42+
This program shows how we can use custom types of classes in a DPC++
43+
program and explains the basic DPC++ implementation including device
44+
selector, buffer, accessor, kernel and command group.

### Running Samples In DevCloud
54+
If running a sample in the Intel DevCloud, remember that you must specify
55+
the compute node (CPU, GPU, FPGA) as well whether to run in batch or
56+
interactive mode. For more information see the Intel® oneAPI Base Toolkit
57+
Get Started Guide (https://devcloud.intel.com/oneapi/get-started/base-toolkit/)
58+
59+
### On a Linux* System
60+
* Build the program using Make
61+
make all
62+
63+
* Run the program
64+
make run
65+
66+
* Clean the program
67+
make clean
68+
69+
### On a Windows* System Using Visual Studio* Version 2017 or Newer
70+
* Build the program using VS2017 or VS2019
71+
Right click on the solution file and open using either VS2017 or
72+
VS2019 IDE.
73+
Right click on the project in Solution explorer and select Rebuild.
74+
From top menu select Debug -> Start without Debugging.
75+
76+
* Build the program using MSBuild
77+
Open "x64 Native Tools Command Prompt for VS2017" or "x64 Native
78+
Tools Command Prompt for VS2019"
79+
Run - MSBuild complex_mult.sln /t:Rebuild /p:Configuration="debug"
