This is my first post here. As a new user of R, I was pleased to discover a simple and elegant way to compute in R the Erlang Loss Function, which I present below. INTRODUCTION The Erlang Loss Function is defined as elf(n, a ) = ( a^n/n! ) / ( 1 + a + a^2/2 + a^3/3! + ... + a^n/n!) for all real numbers a>=0 and all integers n>=0 (except that the function is undefined when BOTH n and a

Hi, I would like to know about which threads will be preempted by which on my OpenSolaris machine. Therefore, I ran a multithreaded program "myprogram" with 32 threads on my 24-core Solaris machine. I make sure that each thread of my program has same priority (priority zero), so that we can reduce priority inversions (saving preemptions -- system overhead). However, I ran the following

Folks, HVM guest crashes when its hypercall is preempted on x86 (pae and 32e) platform. For example, this happens when we install balloon driver and change guest memory size by ''xm mem-set''. The attached patch fixes this problem. Regards, Yu _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

This commit starts to split our massive, monolithic configure.ac file into smaller files, using the m4_include mechanism to combine them. I don't know if we should really do this, so I'm open to comments about it. However: - Our configure.ac script is 1800+ lines long, and that's pretty long. - configure.ac lacks structure; splitting it up might improve that. - From what I read,

DTrace folks, I''m pleased to introduce a potential new DTrace-sponsored project: the Erlang DTrace provider. To be good OpenSolaris citizens, we want to put the formation of this officially sponsored project to a vote -- as outlined in the OpenSolaris Constitution -- so here are the details for the new Project, as prepared by the Project Team: Name : Erlang DTrace Integration

It's not possible to define an action which takes a parameter called 'message' because the Erlang bindings use that as the name of an internal variable.

Hi, Following Chris' advice, I will rebase the patches and break them in 3 distinct emails (one at a time) in order to be easier for a reviewer to approve/comments. Please note that the three patches while being code-wise independent, they 're strongly-connected *semantically*, meaning that including just a subset of these patches to LLVM's code base is quite weak if the others are

Hi, We 've been working on an LLVM backend for High Performance Erlang (HiPE) [1], the native code compiler of Erlang/OTP [2]. ErLLVM [3] targets the X86 and AMD64 architectures for now but there is some ongoing work from a team on the Uppsala University to also support ARM. In our implementation, we have paid special attention on retaining ABI-compatibility with the Erlang Runtime System in

Hello, Has anyone already implemented some sort of call preemption in Asterisk ? I am trying to achieve something like this : - I want to limit the number of calls on a given SIP peer to 10 - on the other hand, some calls have higher priority than others - when the ceiling of 10 calls is reached and a call with a high priority is attempted, I would like to drop a call with a lower priority

This is also happening when using the C++ APIs. It looks like an MCJIT and SetGC interaction. I'm lost on how to proceed further.

The implementation uses the ei_decode_iodata() function which has been introduces only for Erlang 23, so it doesnt work with earlier Erlang versions. --- erlang/Makefile.am | 1 - erlang/main.c | 312 +++++++++++++++++++++++++-------------------
