For around seventy years, 800 rolls of early nitrate film sat in sealed barrels in the basement of a shop. Now miraculously rediscovered and restored, the Mitchell
The goal of Tidydoc is to make documentation organization easier. It addresses the following problems: Add documents to a pool of documents. Give them the right names and put them into the right directories. Reorganize them a posteriori. Generate a set of HTML pages to browse your documents. Generate a bibtex file referencing all your documents.
Evolution of Google File System August 08, 2009 07:26:40 EDT There is an interesting interview about the evolution of the Google File System in ACM Queue. I think it is readable by anybody, not just ACM members. One of the morals of this story is that, even if you are building what you think will be the world's biggest, you still will make design decisions that you know are not scalable because you know how to implement them. It is better to get something running right away and start using it. Of course, they also ran into scalability problems that they did not expect. So, some of the evolution of GFS was planned, and some was unplanned.
VMware to xen migration German original: http://www.eisxen.org/49.html To convert a Linux VMWare Image to a normal image, below the most important commands: install qemu convert the VMware image to a RAW-Image qemu-img convert -f vmdk /var/vmware/vm/vm01.vmdk \ -O raw /tmp/vmimage.raw A vmware imange is a containerfile. The partitions have to be spilt up to individual images for xen. To find out what is in the VMware image, take a look with: fdisk -l -u /home/xen/vmimage.raw Device Boot Start End Blocks Id System linux1 * 63 208844 104391 83 Linux linux2 208845 7550549 3670852 83 Linux linux3 7550550 8193149 321300 82 Linux swap I presume there are already some lvm’s available. Now use the command below a couple times to extract them dd if=vmimage.raw of=/dev/vg01/xendomU01slash bs=512 skip=208845 count=7341705 Of course, check the result (with a (loop)mount)
Re: How migrate vmware guest to xen Hi, It's possible with the qemu tools Install the qemu package (which is available from the OpenSuSE Build Service) and use the following command: qemu-img convert -f vmdk /path/to/vm01.vmdk -O raw /tmp/xenimage.raw This will create a raw disk which can be used with xen from a VMware vmdk disk.
The United States increasingly relies on information networks for the conduct of vital business. These networks are potentially subject to major disruptions from a variety of external sources. To date, there has been no clear statement of the magnitude of this threat or the ability of the various networks to withstand or respond to such disruptions. This project examines the national communications and information infrastructure. The research was conducted for the Office of Science and Technology Policy with task funding from the National Science Foundation.
As computational scientists are confronted with increasingly massive datasets from supercomputing simulations and experiments, one of the biggest challenges is having the right tools to gain scientific insight from the data. One common method for gaining insight is to use scientific visualization, which transforms abstract data into more readily comprehensible images using advanced computer software and computer graphics. But the ever-growing size of scientific datasets presents a significant challenge to modern scientific visualization tools. As a result, there is a great deal of motivation to explore use of large, parallel resources, such as those at the U.S. Department of Energy's (DOE) supercomputing centers, to take advantage of their vast computational processing power, I/O bandwidth and large memory footprint.
With Fibre Channel too expensive for most customers, the Internet Small Computer Systems Interface (iSCSI) protocol is poised to become the standard for architecting dedicated storage solutions. Small-to-medium businesses (SMBs) and enterprise customers alike should prepare for the inevitable adoption of iSCSI by encouraging their information technology staff to learn how to install and configure iSCSI today.

About MacResearch By joel at Sun, Dec 18 2005 2:06pm Mission MacResearch.org is an open and independent community for scientists using Mac OS X and related hardware in their research. It is the mission of this site to cultivate a knowledgeable and vibrant community of researchers to exchange ideas and information, build a community knowledge-base, and collectively escalate the prominence of Apple technologies in the scientific research community.
The newest version of the open source Xen hypervisor has been released, and it features input from some of the industry's largest hardware and software players. The new release boasts better performance and scalability and is designed to work on supercomputers, smartphones and everything in between.
I am currently sitting at the dining table of Peter Murray-Rust with Egon Willighagen opposite me talking to Jean-Claude Bradley. We pulling together sets of data from Jean-Claude’s UsefulChem project into CML to make it more semantically rich and do a bunch of cool stuff. Jean-Claude has a recently published preprint on Nature Precedings of a paper that has been submitted to JoVE. Egon was able to grab the InChiKeys from the relevant UsefulChem pages and passing those to CDK via a script that he wrote on the spot (which he has also just blogged) generated CML react for those molecules.
