Hello, Is it possible to generate simulated data that look like the attached figure? The curve in the figure can be obtained from this equation respecting some conditions: if(Temperature > T_min & Temperature < T_max){ a*( Temperature -T_min)*( Temperature -T_max) } else 0 T_min ~ Uniform(0, 24) T_max ~ Uniform(25, 45) -a ~ Gamma(1, 1) Temperature <- seq(0, 45, by = 1)

Running an mmap-intensive workload on ZFS on a X4500, Solaris 10 11/06 (update 3). All file IO is mmap(file), read memory segment, unmap, close. Tweaked the arc size down via mdb to 1GB. I used that value because c_min was also 1GB, and I was not sure if c_max could be larger than c_min....Anyway, I set c_max to 1GB. After a workload run....: > arc::print -tad { . . . ffffffffc02e29e8

Hi, I am using the ogg123 player through an emacs interface to mpg123 I patched up to support ogg123 (shameless plug, see http://asf.void.at/emacs.html). This has a problem (apart from it being emacs, which might offend some of you (-:): The verbose output from ogg123 is collected and inserted into a temporary buffer. This works when emacs has nothing else to do, but fails when it blocks. Then,

The PE headers of the generated efi file were quite buggy. And since OVMF perform a few consistency checks, syslinux was unable to run on it. I don't pretend to have a thorough understanding of the PE+ headers, some bugs may remain. :) Celelibi (4): efi: Fix PE header field rva_and_sizes_nr efi: Location, size and alignment of .text section efi: Useless relocations in PE file efi: PE

Hi, I am sending this e-mail once again because it probably has been lost in abyss of Xen-devel/LKLM list. Here is the second version of memory hotplug support for Xen guests patch. This one cleanly applies to git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git repository, xen/memory-hotplug head. Changes: - /sys/devices/system/memory/probe interface has been removed;

Hi all I ran a workload that reads & writes within 10 files each file is 256M, ie, (10 * 256M = 2.5GB total Dataset Size). I have set the ARC max size to 1 GB on etc/system file In the worse case, let us assume that the whole dataset is hot, meaning my workingset size= 2.5GB My SSD flash size = 8GB and being used for L2ARC No slog is used in the pool My File system record size = 8K ,

Hello. I have a Solaris 11/11 x86 box (which I migrated from SolEx 11/10 a couple of weeks ago). Without no obvious reason (at least for me), after an uptime of 1 to 2 days (observed 3 times now) Solaris sets arc_no_grow to 1 and then never sets it back to 0. ARC is being shrunk to less than 1 GB -- needless to say that performance is terrible. There is not much load on this system. Memory

There are several bugs at error path of create_snapshot() when the transaction commitment failed. - access the freed transaction handler. At the end of the transaction commitment, the transaction handler was freed, so we should not access it after the transaction commitment. - we were not aware of the error which happened during the snapshot creation if we submitted a async transaction

Hello. We''re currently using a Sun Blade1000 (2x750MHz, 1G ram, 2x160MB/s mpt scsi buses, skge GigE network) as a NFS backend with ZFS for distribution of free software like Debian (cdimage.debian.org, ftp.se.debian.org) and have run into some performance issues. We are running SX snv_48 and have run with a raidz2 with 7x300G for a while now, just added another 7x300G raidz2 today but

We have a 32 GB RAM server running about 14 zones. There are multiple databases, application servers, web servers, and ftp servers running in the various zones. I understand that using ZFS will increase kernel memory usage, however I am a bit concerned at this point. root at servername:~/zonecfg #mdb -k Loading modules: [ unix krtld genunix specfs dtrace uppc pcplusmp ufs md mpt ip indmux ptm

From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially. This patch is developed and on top of the send/receive btrfs and btrfs-progs repo at git://github.com/ablock84/linux-btrfs.git (send-v2) git://github.com/ablock84/btrfs-progs.git (send-v2)

Greetings, all. Does anyone have a good whitepaper or three on how ZFS uses memory and swap? I did some Googling, but found nothing that was useful. The reason I ask is that we have a small issue with some of our DBA''s. We have a server with 16GB of memory, and they are looking at moving over databases to it from a smaller system. The catch is that they are moving to 10g. Oracle

Greeting All I have create a pool that consists oh a hard disk and a ssd as a cache zpool create hdd c11t0d0p3 zpool add hdd cache c8t0d0p0 - cache device I ran an OLTP bench mark to emulate a DMBS One I ran the benchmark, the pool started create the database file on the ssd cache device ??????????? can any one explain why this happening ? is not L2ARC is used to absorb the evicted data

Clean up btrfs_lookup_dentry() to never return NULL, but PTR_ERR(-ENOENT) instead. This keeps the return value convention consistent. Callers who use btrfs_lookup_dentry() require a trivial update. create_snapshot() in particular looks like it can also lose a BUG_ON(!inode) which is not really needed - there seems less harm in returning ENOENT to userspace at that point in the stack than there

One variable contains values (1.30 - one hour and thirty minutes, 1.2 (which is supposed to be 1.20 - one hour and twenty minutes)). I would like to convert to a minute variable so 1.2 is converted to 80 minutes. How?
