New server chips from Intel on the way

The Register has obtained a slide describing the next families of Xeon processor to be released by Intel, the Purley platform which includes Skylake.  There are some interesting new developments, including on die interface for either 10Gb/sec Ethernet or 100Gb/sec Omni-Path fabrics which interested the participants at the HPC conference the slides were shown at.  They also mentioned a brand new memory architecture which is described as offering four times the capacity and 500 times the speed than current NAND, all at a lower price per chip which is likely to be somewhat of an exaggeration on their part.  There were also new Phi chips, including the long awaited Knights Landing and workstation chips for use outside the server room.

"A presentation given at a conference on high-performance computing (HPC) in Poland earlier this month appears to have yielded new insight into Intel's Xeon server chip roadmap.

A set of slides spotted by our sister site The Platform indicates that Chipzilla is moving toward a new server platform called "Purley" that will debut in 2017 or later."

A tiny little Broadwell powered PC; the Shuttle Fanless Slim-PC DS57U

Subject: Systems | May 26, 2015 - 02:37 PM |
Tagged: shuttle, SFF, fanless, Broadwell, DS57U, Celeron 3205U

The Shuttle DS57U is powered by a dual core Celeron 3205U running at 1.5GHz and a nice and cool 15W TDP.  The system supports up to 16GB of DDR3 at 1.35 V, no 1.5V DIMM that TechPowerUp tried would work and for add-in cards you have a single full sized mini-PCIE slot and a half sized mini-PCIE slot which is already occupied by a WLAN card.  The system does have only one SATA 6Gbps port so external storage may be necessary, thankfully there are a pair of USB 3.0 ports and four USB 2.0 ports.  This model is available for $250 currently, if you decide you need more power there are several versions going all the way up to the DS57U7 powered by an i7-5500U.  If you are looking for an inexpensive SFF barebones system, Shuttle is not a bad choice overall and the DS57U is worthy of consideration.

"The Shuttle DS57U is a slim barebone PC that only needs RAM and a HDD or, even better, an SSD to boot. It comes with an Intel dual-core Celeron processor (Broadwell) and features lots of I/O ports, which make it suitable for a wide range of applications."

One last look at GTAV graphics settings

Subject: General Tech | May 27, 2015 - 01:30 PM |
Tagged: gaming, GTAV, VLAN party

[H]ard|OCP is concluding their series on GTA V graphical settings with a look at various anti-aliasing technologies and shadowing options. Their testing shows that TXAA has a much greater effect on textures than FXAA but that change is not necessarily a good thing for your textures.  MSAA is not only less than effective in the game but also comes with a performance hit that makes it a rather unattractive option except in certain situations.  They also cover AMD CHS and NVIDIA PCSS soft shadow technologies and the visual effects that high resolution shadows provide.  If you are still tweaking your GTA V settings then head over to check the review out.

Make sure to head over to the Gaming forum if you haven't already as this Saturday May 30, starting at 10:00 AM ET it is the Fragging Frogs Virtual LAN party #10.  You need to confirm your attendance in this thread if you want a shot at some of the many prizes being given out by AMD, Fractal Designs and maybe even other secret prizes.  The thread also covers how to log into the TeamSpeak server as well as the gamut of games likely to be played; make sure you install any patches or mods before we kick off to maximize your gaming time.

"In our final look at Grand Theft Auto V we will look at image quality comparisons in this game. We will focus on the main graphics options that affect performance the most and we will get to the bottom of which soft shadow option is best to use. We will also find out if FXAA and TXAA affect texture quality."

Checking out the high end model of the Asus Transformer Book T300 Chi

Tagged: asus, transformer book, T300 Chi

The ASUS Transformer Book T300 Chi comes in a number of models, with the base mode running just under $700.  The Tech Report had a chance to review the higher end model which is more expensive and harder to find.  This particular model sports a 2.9GHz Broadwell based Core M 5Y71, 8GB DDR3-1600 and an internal 128GB internal SanDisk iSSD.  The 12.5" IPS 2560x1440 screen is common to all models, as is WiFi connectivity and Windows 8.1, 64-bit.  The keyboard portion of this Transformer Book is more of a screen stand than a dock as it uses Bluetooth to connect to the tablet as opposed to a physical interface, magnets keep the tablet in place when you are docked.  Check out how well it performs in The Tech Report's full review.

"Asus' Transformer Book T300 Chi combines Intel's Core M processor with a 12.5" high-PPI display. The tablet half of this detachable 2-in-1 is thinner than the iPad Air, and it's backed by a keyboard dock that attaches with neodymium magnets. Read on to see what the T300 Chi is like as a tablet and notebook."

Running an EXT4 RAID on the Linux 4.0 kernel? Better spray for bugs!

Subject: General Tech | May 21, 2015 - 12:40 PM |
Tagged: linux, EXT4, raid, bug

On Tuesday a bug was discovered to have been introduced to Linux 4.0 kernel when a fix was added to deal with RAIDs where the chunksize not a power of 2, a problem present since Linux 3.14-rc1.  This fix has been causing corruption on RAIDs and the file system on that RAID, making many an unhappy Arch Linux user.  Only users of rolling release flavours will be effected, distros with scheduled updates like RHEL or Ubuntu are not effected at this time.  The good news is that as of today there is a fix available if you wish to apply it, as well as defining the fix which caused the issue.  Check out both at Phoronix.

"A few days ago we reported on an EXT4 file-system corruption issue being discovered within the stable Linux 4.0 kernel series. The good news is the issue has been uncovered and a patch is available, but it could still be a few days before it starts getting sent out in stable updates."
