flops calculation
Hi all,
Since proc.time return three different kind of times (user, system and
elapsed) , I am wondering which one is right for calculating flops. In New S
Language (Becker et. al. ) , it seems to be the user because " the user time
measures the processor time used in S and the system time measures the
operating system in response to S's request". But in R Help , system time
sounds better as " The first two entries(refer...

zfs send/recv reliability
After looking through the archives I haven''t been able to assess the reliability of a backup procedure which employs zfs send and recv. Currently I''m attempting to create a script that will allow me to write a zfs stream to a tape via tar like below.
# zfs send -R pool at something | tar -c > /dev/tape

Speex FLOP requirements
Jean-Marc,
I'm an embedded systems designer and am in the process of selecting a
hardware
platform to run a Linux-Speex VoIP application. Being concerned with size
and
power consumption I must choose a processor with a minimal amount of
computational power. To that end I've narrowed my search to number of
different products that reference the popular "SiSoft Sandra(TM)"

Well, heratbleed and shellshock were pretty much global: all systems (not
only Linuxes, not to say particular Linux distributions - my FreeBSD boxes
were affected too) using openssl or bash were affected... Same bad, yet
these were not flops of particular distribution, so whichever system you
decided to stick with , you had these. Not certain about you, but this
kind of makes difference for me. When I say I'm happy about [me choosing
way back] RedHat heartbleed, no heartbleed, no difference.

I have verified. It indeed does not involve Polly Dependence analysis. "Polly Dependence Pass" for flop is still high for some benchmarks as we have discussed before.

LocalDiscovery flip flopping and network design tips
Can you specify which version of tinc you're using? There are vast
differences in the way LocalDiscovery works between 1.0 and 1.1. The former
uses broadcast, the latter unicast to explicitly advertised local addresses.
You say that tinc_test_1's eth0 interface is configured with 10.240.0.4,
and tinc_test_2's eth0 interface is configured with 10.240.0.5. How are the

No. The Subnet option deals with routing *inside* the VPN, not the
underlying "real" network.
In tinc 1.1, the address that local discovery probes are sent to is

PXE over HTTP instead of TFTP - flip flopping OS boots
Is there a way to boot PXELINUX 100% over HTTP instead of TFTP? I can
pull over pxelinux.0 via HTTP (DHCP config) but all the config files
are pulled over via TFTP.
DHCPD config file example:
filename "pxelinux.0" ; # boots via TFTP
filename "http://10.1.1.10/pxelinux.0" # boots via HTTP
My goal is to alternate booting between Linux and Memtest for some
hardware stress

FW: How do I emulate a harddrive instead of a flop py?
OK, seem to have answered my own question... I think. We'll see how it works out. Basically I should've been asking for some help in the dosemu forums because that's where I needed the help. I think I get it now....
mkdiskimage whatever size you need
Set up dosemu to boot the precise DOS flavor you want from mounted folder
also mount the image as secondary HDD

...some domains and we do want to vectorize them. I skimmed through the IR and the assembly and I did not see anything too bad. The next step would be to do a binary search on the places where the vectorizer fires to locate the bad pattern.
On AVX we have another regression that I did not mention: Flops-7. When we vectorize we cause more spills because we do a poor job scheduling non-destructive source instructions (related to PR10928). Hopefully Andy’s scheduler will fix this regression once it is enabled.
I did not measure code size, but I did measure compile time. There are 4-5 workloads (n...
