R: Securities earning covariance
 
|
Good morning. I have a real fuzzy question to ask; we have a calculation engine which is composed by n virtual machines each of them with a jvm 2GB of memory on Linux Red Hat each of them with the "R" package which comes along with the Red Hat Linux distribution. We have now to increase the number of "nodes" trying to avoid to use new virtual or physical machines. So my question is: is it possible to install multiple jvm on the same machine each of them with its independent instance of R ? Should I "duplicate" the initial R installation to get different instances with different libraries ? Is it enough or even in this case the different instances "share" something so they are not really "fully independent" ?

I'm somewhat confused:
i) What does this have to do with your subject line? ii) There does not exist -- to my knowledge -- an implementation of R which runs on the JVM. iii) Have you simply looked into R's native parallel computing options? That seems to be (maybe?) what you are trying to do. Incidentally, thanks to the in-memory model, it is possible to spawn multiple R processes which use the same package libraries [the package is the thing in the library, which is tied to the filesystem] on the same machine (I'm thinking real, but this shouldn't be a problem with a reasonable VM setup either) Michael On Fri, Jun 15, 2012 at 3:05 AM, <[hidden email]> wrote: > > Good morning. > > I have a real fuzzy question to ask; we have a calculation engine which > is composed by n virtual machines each of them with a jvm 2GB of memory > on Linux Red Hat each of them with the "R" package which comes along > with the Red Hat Linux distribution. > We have now to increase the number of "nodes" trying to avoid to use new > virtual or physical machines.

Hello,
first of all tank to both of you for your fast response. Going back to Michael's wonderful ASCII art masterpiece, what we have now is something like this: ------- JVM ----------- ---- JAVA ---- JDBC | | Algorithm | ---- JAVA ---- ------- JVM ----------- | RNI | R What we want is something like the following (on the same virtual machine): ------- JVM1 ----------- ------- JVM2 ----------- ---- JAVA ---- ---- JAVA ---- JDBC JDBC | | | | Algorithm Algorithm | | ---- JAVA ---- ---- JAVA ---- ------- JVM1 ----------- ------- JVM2 ----------- | | RNI RNI | | R(1) R(2) My question is: is that possible ? How can I address R(1) from JVM1 and R(2) from JVM2 ? Is data calculated in R(1) and R(2) completely independent or the 2 instances "share" something in memory ? Thanks again for you kindness and help. Angelo -----Messaggio originale----- Da: Oliver Ruebenacker [mailto:[hidden email]] Inviato: venerdì 15 giugno 2012 17.36 A: R.

Best I understand it (and RNI seems Windows-only so I can't verify) you have nothing to worry about. As long as you start 2 R processes (which seems to be the only thing that could happen with two JVMs) the memory should be kept independently. The only exception I can think of is that if you choose to install a new package on one R process it might be available to the other as a read-only resource (but I'm not sure even this would happen depending on how your VM handles that bit) but data integrity should be guaranteed.

Yes, that seems to be the issue at play and best I understand the set-up you get this "for free" from the in-memory model. You shouldn't need two R installations any more than you need to install the JVM twice to run two JVMs on one box.

Hello,
By RNI, do you mean the Microsoft Raw Native Interface or the Rengine R Native Interface?
