Hi: I am a new R user. I have the following question and would appreciate your input Data1 (data frame 1) p1,d1,d2 (p1 is text and d1 and d2 are numeric) xyz,10,25 Data2 (data frame 2) p1,d1,d2 xyz,11,15 Now I want to create a new data frame that looks like so below. The fields d1 and s2 are summed by the product key. Data3 p1,d1,d2 xyz,21 (sum of 10 from Data1 and 11 from Data2),40 (sum of 25

I am new to LLVM and I am interested in using LLVM for an application that I plan to develop on Solaris. I want to execute the generaed code on different machines (both little endian and big endian). In my application endianess is important. How does LLVM deal with Endian issues? Does LLVM take care of byte swapping? Thanks __________________________________ Do you Yahoo!? Yahoo! Mail

Three patches to clean up GDT access in Linux to make it friendly to virtualization environments. The basic problem is that the GDT must be write protected, which causes spurious overhead when the GDT lies on the same page as other data. This problem exists both for VMware and Xen; Xen actually requires page isolation, so we have implemented the most general and compatible solution. Patch 1

I would like to host a phone meeting to discuss the plans for the xen sub-architecture of x86. Hopefully Chris can share his vision and we can agree on some next steps to getting this done and into the mainline kernel. From my understanding, it would be good if the "To" list could make it. If anyone believes others should attend, please let them know. Please let me know if you are

In OLS 2005, we described the work that we have been doing in VMware with respect a common interface for paravirtualization of Linux. We shared the general vision in Rik's virtualization BoF. This note is an update on our further work on the Virtual Machine Interface, VMI. The patches provided have been tested on 2.6.16-rc6. We are currently recollecting performance information for the new
