Hey Folks,
Doing simple floating point or integer arithmetic is limited since if another execution core is not busy, the system will (presumably?) assign CPU resources to where they are needed so I could be getting the performance of 2 or more cores theoretically?
Any good reliable way to... (2 Replies)
Hello all.
I have a script that uses two arrays in the beginning. Saves certain values that i am extracting from df -h command.
array1 and array2 where i is from 0 to 9.
It then goes on and saves the values of the arrays into variables.
for i 0 to 9 , tmp= array2 // I am no writing the... (4 Replies)
Hi,
We have IBM P-Series servers (P690, P650) equiped with AIX 5.2.
Further we have 10/100 MB ethernet cards in P650 and 10/100/1000 MB ethernet cards in P690 servers. Servers are on a LAN connected with Cisco 3750 catalyst switch. FTP from one server to another is very slow,,,even 3-4 MB... (3 Replies)

VIOMB(4) BSD Kernel Interfaces Manual VIOMB(4)NAME
viomb -- VirtIO memory ballooning driver
SYNOPSIS
virtio* at pci? dev ? function ?
viomb* at virtio?
DESCRIPTION virtio(4) defines an interface for efficient, standard, and extensible I/O between the hypervisor and the virtual machine. The viomb driver
supports the virtio-compliant memory ballooning device.
Memory ballooning works as follows:
1. The host operator requests a guest to return some amount of memory to the host (via e.g. Qemu monitor balloon command).
2. The hypervisor sends the request via VirtIO memory ballooning device.
3. The guest viomb driver requests allocation of that amount of physical memory from the NetBSD memory management system.
4. The viomb device tells the hypervisor the guest physical memory address of the allocated memory via VirtIO memory ballooning device.
The sysctl node hw.viomb.npages shows the requested number of memory pages to return to the hypervisor, while hw.viomb.actual shows the
actual number of memory pages that are already returned to the hypervisor.

HISTORY
The viomb device driver appeared in NetBSD 6.0.
BUGS
The userland interface should be same as the Xen ballooning device.
