		<title>ZFS on Linux, Part 2</title>
		<description><![CDATA[There are many tutorials out there for using ZFS tools zpool and zfs, so I&#8217;ll just summarize some points below. Instead of partitioning a disk to several filesystems, in ZFS, there is a concept of a &#8220;storage pool&#8221; of devices, where filesystems are created in that pool.  Consequently, zpool is used to manage the storage [...]]]></description>

		<title>Minus &#8211; file sharing</title>
		<description><![CDATA[I&#8217;ve been a big fan of Dropbox for a while, and I use it to share pictures and video with family.  What is nice is being able to sync files in the background on a folder, so we can send each other updated files automatically without having to notify each other. Recently, though, I&#8217;ve started [...]]]></description>

		<title>Google Authenticator</title>
		<description><![CDATA[Google Authenticator provides 2-step verification for Gmail.  When on travel and using other computers, it provides a little extra layer of security for paranoid individuals such as myself. A verification code on my Android phone (also works with iPhone or BlackBerry smartphones) is needed in addition to my password to login, so unless someone has [...]]]></description>

		<title>Compiling ANSYS 13.0 Custom Executable</title>
		<description><![CDATA[On 64-bit Windows when compiling a custom executable in ANSYS 13.0, an error regarding &#8220;freeMatrixOnGPU&#8221; may occur while linking.  If this occurs, edit the &#8220;ansysex.def&#8221; file with a text editor and remove the line &#8220;freeMatrixOnGPU&#8221; to get the linking process to complete successfully.]]></description>

		<title>ZFS on Linux, Part 1</title>
		<description><![CDATA[ZFS is a filesystem that has a lot of very nice features.  It&#8217;s not native to Linux like Btrfs, but it has similar features and is a bit more mature. I still have my VIA ARTiGO A2000 that I use for a home server, mostly for storing important files.  A RAID1 setup is nice in [...]]]></description>

		<title>GPU Accelerator, Part 3</title>
		<description><![CDATA[The GPU Accelerator capability in ANSYS 13.0 can also be used for the PCG iterative solver.  However, one will usually find a much greater performance boost when using GPU Accelerator with the sparse direct solver.  One of the reasons is due to the fact that running GPU Accelerator with the PCG solver may be constrained [...]]]></description>

		<title>Specifying a Spring/Damper with Frequency-Dependent Values</title>
		<description><![CDATA[Users may wish to include a 1D spring/damper with frequency-dependent stiffness or damping values.  One could use COMBI214 with frequency-dependent values.  Although the frequency-dependent values refer to the spin velocity (tables with OMEGS independent variable), one could use a trick where only the COMBI214 elements are in an element component which has rotational velocity (CMOMEGA) [...]]]></description>

		<title>GPU Accelerator, Part 2</title>
		<description><![CDATA[As noted in the Mechanical APDL Help manual, in the Advanced Analysis Techniques Guide Ch. 16 &#8220;GPU Accelerator Capability&#8221;, when using GPUs, the entire solution does not use the GPU cores &#8211; only the equation solver portion is off-loaded to the GPU.  GPUs cannot interpret data the same way as CPUs, so data needs to [...]]]></description>

		<title>GPU Accelerator</title>
		<description><![CDATA[New in 13.0 is the GPU Accelerator capability. When using a supported graphics card (namely, NVIDIA Tesla cards) and having an ANSYS HPC Pack license, one can take advantage of the cores on the graphics card for the computation.  Unfortunately, this doesn&#8217;t work on any graphics card — for example, many graphics cards only use single-precision [...]]]></description>

		<title>Solver Working Directory</title>
		<description><![CDATA[It&#8217;s been a while since I&#8217;ve added a blog entry&#8230; Although this may be common knowledge, I come across users using non-optimal configurations to solve analyses, so I thought I&#8217;d add this post. One should always solve on a local disk &#8211; ideally, have a RAID0 configuration to make disk access as fast as possible. [...]]]></description>
