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(refe...

...re 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 I''m primarily concerned with in the possibility of a bit flop. If this occurs will the stream be lost? Or will the file that that bit flop occurred in be the only degraded file? Lastly how does the reliability of this plan compare to more traditional backup tools like tar, cpio, etc...? Thank you for any future help Greg -------------- next part ------------...

...oft Sandra(TM)" wetstone bench-mark test for floating point performance. Given that hardware manufacturers shamelessly choose the most favorable test conditions to maximize their product's apparent performance, for example operands may be stored and fetched solely from cache, do the Speex FLOP requirements given in the table four of the manual correlate well to a stated hardware manufacturer's FLOP performance? By comparison, would you share the wet/drystone performance figures for any of the test and development systems used during Speex development and test? Sincerely, Dave Da...

Although I've not seen this kind of flip-flopping behavior myself, it is possible this behaviour occurs, although it should only happen in the first 10 seconds or so.

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 the local

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

...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 (...
