r - parallel computing of a function with doSMP on Windows -


I am trying to multicore a function (in Windows), at which point, another workhorse function (function Calls within the function). Here's the least work example, you'll need a doSMP and revoIPC package (to get them, see the rhythm post). 

  func1 & lt; - Function (x) {Sqrt (x)} func2 & lt; - Function (y) {func1 (y)} Library (doSMP) wrk & lt; - startworkers (worker coat = 4) # I have 4 cores, so register your specs register dosmg (wrk) obj result and lieutenant; The above routine does not work, but if I do nest  func1   func2 - foreach (i = 1: 10000)% dopar% func2 (i)  

  func2  - Function (y) {func1 & lt; - Function (x) {sqrt (x)} func1 (y)}

The process goes through easily (as far as I can tell).

How do I call a function from the outside with % dopar% ?

This looks like a scoping issue

Your func1 call is known in the workspace but the calculation is not on the node, there are solutions for this, e.g. A complete widget is entitled in the package.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
