...or so it starts with it's end. For better understanding, this set of commands will do what I need: i <- seq(1:10) i_turned <- i for (j in 1:length(i)) i_turned[j] <- i[length(i)-j+1] now, i_turned is what I call turned. Is there a function which would make a script lighter? Thank you upfront for any hint. Best regards, Zroutik [[alternative HTML version deleted]]

How can I map from a domain to the IP(s) given to its network interfaces? I'm not specifying a <mac .../> to the domain, so I don't have an upfront mapping setup. Is the best way to do some upfront mapping, e.g. install static MAC -> IP in the DHCP server and add <mac .../> to my domains? Best, matt

Add optional MSI-X support: use a vector per virtqueue with fallback to a common vector and finally to regular interrupt. Teach all drivers to use it. I added 2 new virtio operations: request_vqs/free_vqs because MSI needs to know the total number of vectors upfront. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> --- Here's a draft set of patches for MSI-X support in the guest. It still needs to be tested properly, and performance impact measured, but I thought I'd share it here in the hope of getting some very early feedback/flames....

When writing a JIT compiler using LLVM, as I understand it, you can use two alternative APIs, MCJIT and Orc. The latter offers lazy compilation. Would it be accurate to say that if you want eager compilation - always compile an entire module upfront - you should use MCJIT? -------------- next part -------------- An HTML attachment was scrubbed...

Can anyone recommend any wholesale SIP termination providers that will automatically charge a credit card? Most seem to want upfront payment and a credit balance but that sucks when you have to watch it like a hawk to make sure the balance never hits zero.

Hi, I think it is time we start preparing and managing correctly a Xen Development wiki page. We already have one but it is a bit un-organized, with stale and poor content. I wanted to organize the page like that: - Have upfront a list of tasks, divided by subsystem (es. toolstack, hypervisor, domain support, etc.) - Have the corresponding entries organized like that: o Technical contact (this may be optional if we think the idea is worthwhile but there is not really someone which can tackle this right now). There ma...

My understanding is that Orc is strictly more flexible than MCJIT. You can, in fact, exactly implement the MCJIT API using the Orc APIs. I think the general advice is that MCJIT's a bit more mature and stable, but you probably want Orc in new code unless you re...

...ollowed? A policy saying llvm should not crash on any input is as relevant as one that says that clang should keep bootstrapping in under one second. So, if we stick to reality, what we have is that lld (ELF and COFF) are already the most reliable parts of the toolchain. If not for Rui and I being upfront about it most people would not even know that you could crash it. So please, just let us keep working on the most reliable part of the toolchain. Cheers, Rafael

Anybody would be so kind and point me to the right direction where I can find other fitting possibilities? Thank you for listening and kind answers upfront.

...k functions as pointers to functions to a jitted function. The generated code should use pointer to functions instead of predefined function names in calls. 3. Create you own Memory Manager that will provide addresses to callback functions. Because the set of callback functions is known upfront and quite small that seems to be better than 1.

Hi, I am really confused about NPT walks for guest page table , and eager to know the details about it. It is treated as data writes even if the access itself is a code read in AMD NPT.I just want to know : is it the same in EPT? Could anyone help me? I would like to know that very much Thank you in advance Bo Ma _______________________________________________ Xen-devel mailing list

Hello experts, We have a large implementation of Symantec Netbackup 6.0 with disk staging. Today, the customer is using VxFS as file system inside Netbackup 6.0 DSSU (disk staging). The customer would like to know if it is best to use ZFS or VxFS as file system inside Netbackup disk staging in order to get the best performance possible. Could you provide some information regarding this

Hi all, I'm looking to add a "density" smoother on top of a hist when Freq=T. In order to do this I can use the relation between count and density, but I would like to know if there is a way for me to predict it upfront. Here is an example: set.seed(242) z = rnorm(30) hist_z <- hist(z) hist_z$counts / hist_z$density # the relation is 15 # why is this 15 ?? # So I can now do: hist(z) y <- density(z)$y * max(hist_z$counts / hist_z$density, na.rm = T) # this is what I hope to find without using hist, and onl...
