How well does Visula scale?

Visula Frequently Asked Questions
Obviously being a new and experimental language, Visula has not been used for any particularly large projects. However Visula is designed to be scalable, which it achieves through the following ways: Visula supports independent module compilation, each module being easily in excess of several thousand lines long.

Does Visula have arrays?

Visula Frequently Asked Questions
Yes - RFTM! Visula does not have a built-in notation for arrays. Instead it treats arrays as objects, and uses method calls to access the array. This is better because it does not introduce a (redundant!) notation for arrays, and because dynamic typing allows an algorithm to work on any type of container (e.g. a linked list) without hard-coding the fact that we are dealing with an array. This kind of flexibility was introduced in the C++ standard template library.

How does Visula compare with other languages?

Visula Frequently Asked Questions
The language is actually very simple, and resembles Smalltalk, or even Simula. Due to the constraints of visual programming, the syntax needs to as simple as possible, to reduce the amount of visual clutter and input required by the user. Thus Visula is dynamically typed - types of variables do not need to be declared, rather they depend on the value actually assigned. Visula has no concept of global scope (except for the special std object), all classes in Visula are nested.

Does Visula have classes or prototypes?

Visula Frequently Asked Questions
In dynamic typing, the "class" of an object is almost completely irrelevant. You call a method on an object, and it either works or it doesn't.

How well does the benchmark scale in both scale-up and scale-out configurations?

SPECjAppServer2004 Frequently Asked Questions
SPECjAppServer2004 has been designed and tested with both scale-up and scale-out configurations. The design of the benchmark does not limit the scaling in either way. How well it scales in a particular configuration depends largely on the capabilities of the underlying hardware and software components.

What is Visula?

Visula Frequently Asked Questions
Visula is a visual programming language (VPL). It is a programming language that uses a graphical notation to express programs. An overview of the language can be found here. The purpose of Visula is to provide a full programming language for application development. This remains a challenge for visual programming, since mainstream application development is still based on text. It is an interesting question as to whether visual programming will eventually supersede text.

How does the Handle System Scale?

HANDLE.NET FAQs
Quantity of requests. If there are typically more requests per unit time than a given server can handle, the load on that server can be reduced by spreading it across more servers at that particular site. If a site becomes overloaded, one or more "secondary" sites may be used to replicate the primary site and thus to offload it. Quantity of data: If a single namespace becomes too large to be housed on a single server, it can be distributed across multiple servers that make up a site.

Why should I switch to Visula?

Visula Frequently Asked Questions
Some people really enjoy using visual programming languages, and use of visual languages is ultimately down to programmer preference. Subjectively, it provides a more tangible, cohesive, and perhaps a more natural representation of code. Visula has dynamic typing. This is a better choice for novice programmers who do not need to learn vast and complicated rules governing types.

What is the performance of Visula?

Visula Frequently Asked Questions
Interpreted in the environment. This is the slowest, and types determined at run-time. External C functions are loaded from DLLs. Compiled to C. This is not as fast as native C code, since the language is still dynamically typed. External C functions are statically linked into a stand-alone executable. Modules are compiled independently. No performance tests have been carried out, however I don't expect Visula to break any speed records.

How does it scale?

DMP FAQ
Domains with more SMTP traffic will benefit more from DMP than domains with less traffic. Testing over nineteen-thousand domains over an eighteen month period (June 2002 to November 2003) showed an average increase in bandwidth of 4.15%, not including Time-to-live caching supported by most DNS server software, with roughly 33% of those domains only experiencing less than 1% of an increase. That increase also did not take into account the bandwidth saved by refusing forged e-mail.
Related Questions

Are there any new concepts in Visula?

Visula Frequently Asked Questions
However the notation is completely unlike any other VPL, so therefore it is new. Sequence diagrams are well proven in other contexts, yet have not been used as a basis for a VPL before. The way nesting and folding works is also completely new. The way classes and functions are nested, and the way functions and classes share much of the same syntax, is also new. A programmer wanting to do a real programming task is obviously better off using a mainstream language.

How well does Linux scale for SMP?

The linux-kernel mailing list FAQ
REG) Reasonably well. Kernel version 2.2 has much better scalability than version 2.0. People are running 4 processor Intel Xeon machines and 14 processor UltraSparc machines. Version 2.2 still has a global kernel lock, but this is often released quite quickly (for example, when the process blocks waiting for a resource and/or data), so the net result is that it is quite unlikely for two processors to compete for the global lock.

Is Visula suitable for end-users?

Visula Frequently Asked Questions
No, Visula is primarily a programming language, not an end-user language. Its syntax is abstract, since Visula programs do not correspond to visual things. The editor is also very unusual compared to a basic text editor. While in the future, it would be nice to tell your computer "write me a program to play chess - here are the rules of the game", at the moment we still need to fill in the missing steps.

Does it have scale panel lines and rivet spacing?

P-51D FAQ
The panel lines we have are for the most part in scale locations, however we don't have all of the panel lines that the full size airplane has. The rivet spacing is not scale. We have a couple of ideas in the works to do a better job of simulating scale panel lines and rivets at a small increase in cost. We could do real panels and rivet spacing if you want it, but expect to pay considerably more.

Why does my weight go up and down every time I step on the scale?

Women's Nutrition FAQ
Consider the normal body functions that occur everyday. The human body is always in a constant state of change; therefore, no one's body weight remains constant. A persons lean body mass can move up or down by one to five pounds on any given day. These gains have nothing to do with body fat, but have more to do with other things going on in your body, such as, Water retention, hydration levels and the time of day can contribute to variations in body water.

How does the scale right-out-of-the-box work?

EPGFA FAQ's
The idea here is simple. Most common, high-quality scales are accurate when new. The EPGFA does not want to put the burden of getting the new scale certified before a record fish is caught. However, the scale to be certified must be in like-new condition, and, if it does not pass, the record will be disqualified. This rule allows anglers to go ashore, buy a scale if they do not have one, and submit it with the record application in order to receive the recognition they deserve.

How does Trike scale?

Trike: FAQ
The current tool implementation suffers from the same scalability issues as the methodology. We do not currently have automated support for the suggested methodology workarounds, but the tool wouldn't impede them in any way.In addition, when the rules for a particular action develop a large number of atomic clauses, operations involving the rules become slow in the current Trike implementation. If this is causing trouble for you, please let us know -- large improvements are probably possible.

Internet Scout Project - CWIS
One of the CWIS development installations at Scout is normally loaded with 15,000 records and runs on a 500 MHz Celeron system (circa 1999), with no noticeable degradation in performance. The two CPU-intensive operations in CWIS are updating the search database and updating the recommender system (both of which are done when adding or editing records), and faster hardware may be desirable to ensure that those operations happen in a timely manner.
