I''m not sure if the author of the paper is aware of this, but there is a very easy to use library that just loving does all this webview stuff for you - the CEF (https://bitbucket.org/chromiumembedded/cef). Example applications that use CEF include Adobe Acrobat, Steam, Battle.NET, Unreal Engine, Unity, Discord.... It works on Mac/PC/Linux, and in addition to working with C/C++, also has bindings for Python, Java, .NET, Ruby, Go, Swift, Delphi....

The fundamental problem with Rust is that it is not the language their game engine is already written in.

I spend all my free time writing angry emails to people whose software doesn't accept my email addresses with extra "@" signs in them enclosed in double quotes. Unfortunately none of those emails are ever received because i send them all from an email address that is composed entirely of punctuation characters, vertical tabs, and probably that one that makes the computer beep as well.

If you want to insert a new parameter, you don't want to have to bump the indeces of all the other ones.

Also, If you name things properly, you don't need comments. So, if you do make a comment, just repeat the names of the variables.

Well, the researcher problem is to document a parameter called "u" with the description "u". The weird parameter indexing is just... I don't know.

This is from Rodinia, a benchmark suite that is unfortunately very popular. These superficial issues are the smallest problem. The bigger problem is that this benchmark suite is not even consistent in how it does profiling or validation (but that's harder to fit in a code block).

There are also Actual CUDA Problems with this code; in particular a charming naivety about how you should access memory on a GPU. But that is now what we are here for. This is what we are here for. Here's a teaser:

code:

	// variable references
	int offset_1;
	int offset_2;
	int offset_3;
	int offset_4;
	int offset_5;
	int offset_6;
	int offset_7;
	int offset_8;
	int offset_9;
	int offset_10;
	int offset_11;
	int offset_12;
	int offset_13;
	int offset_14;
	int offset_15;

And then later:

code:

	offset_1 = valu_offset;
	offset_2 = valu_offset+1;
	offset_3 = valu_offset+2;
	offset_4 = valu_offset+3;
	offset_5 = valu_offset+4;
	offset_6 = valu_offset+5;
	offset_7 = valu_offset+6;
	offset_8 = valu_offset+7;
	offset_9 = valu_offset+8;
	offset_10 = valu_offset+9;
	offset_11 = valu_offset+10;
	offset_12 = valu_offset+11;
	offset_13 = valu_offset+12;
	offset_14 = valu_offset+13;
	offset_15 = valu_offset+14;

How are these handy constants used, you ask?

code:

	// decoding input array
	CaM				= d_initvalu[offset_1];
	Ca2CaM			= d_initvalu[offset_2];
	Ca4CaM			= d_initvalu[offset_3];
	CaMB			= d_initvalu[offset_4];
	Ca2CaMB			= d_initvalu[offset_5];
	Ca4CaMB			= d_initvalu[offset_6];           
	Pb2				= d_initvalu[offset_7];
	Pb				= d_initvalu[offset_8];
	Pt				= d_initvalu[offset_9];
	Pt2				= d_initvalu[offset_10];
	Pa				= d_initvalu[offset_11];                            
	Ca4CaN			= d_initvalu[offset_12];
	CaMCa4CaN		= d_initvalu[offset_13];
	Ca2CaMCa4CaN	= d_initvalu[offset_14];
	Ca4CaMCa4CaN = d_initvalu[offset_15];

The other problem is half of them are constants that likely don't change. It's almost like a struct could be useful there so you don't have 13.75 parameters that largely don't describe what's happening, what state is modified, etc. Instead you'd have the business side of the variables being passed in 6 parameters and a struct containing "constant" environmental stuff that's likely passed to other functions, or 'kernels' as the gpu nomenclature goes, as well.

Maybe I am the horror here, I don't know.

edit: for example, one instance of my program will have 12 variables that don't change during the life of the program but you might stop your program, change the settings, and restart your program. I usually establish a struct for "settings" and then either pass it to relevant functions or keep it as a global. Stuff like time step size when it's constant, bounding box, particle count if it never changes, that kinda stuff.

Yeah, that was my guess. Someone wrote up a paper saying "here's some math to accomplish this desired result", then the math got turned into a program with as few changes as possible. Happens all the time, sadly. I very much doubt the software engineer aspiration of "meaningful variable names" is going to shift several centuries' worth of single-letter variable names in the world of mathematics.

Single letter variables are cool and good if used sparingly and carefully. 'i', 'j' and maybe 'k' are nice loop indices ('l' would be pushing it). Shut up, weirdoes who use quaternions.

If you�re doing textual find and replace on variable names in 2018, you�re doing something wrong. Use the �rename variable� function in your editor. If you�re using an editor without such a function, get a better editor.

(If you�re using a language without such an editor, I suggest polishing your resume.)
