Fixstars Solutions, Inc is a software and services company specializing in Multi-core processor, particularly in the Nvidia's GPU and CUDA environment, IBM Power7 and Cell.During the early part of 2010 Fixstars developed a strong relationship with Nvidia and focused its linux distribution for GPU computing. Yellow Dog Enterprise Linux for CUDA is the first enterprise Linux OS optimized for GPU computing. It offers end users, developers and integrators a faster, more reliable, and less complex GPU computing experience.On November 11, 2008, Japanese company Fixstars announced that it had acquired substantially all of Terra Soft's assets. Terra Soft's former founder and CEO Kai Staats was appointed as COO of Fixstars's new American subsidiary, Fixstars Solutions, which is based in San Jose, California, while retaining Terra Soft's product line, staff and regional offices in Loveland, Colorado.Terra Soft provided software and services for the Power Architecture and Linux OS platform. Former Terra Soft Solutions produced Yellow Dog Linux and Yellow Dog Enterprise Linux which included cluster construction tools. Customers included Argonne, Sandia, Lawrence Livermore, and Los Alamos National Labs, several Department of Defense contractors including Boeing, Lockheed Martin, and SAIC; the U.S. Airforce, Navy, Army, and NASA; and many of the top universities around the world including California Institute of Technology, MIT, and Stanford University.As an Apple value-added reseller and IBM Business Partner, Terra Soft Solutions provided turnkey and build-to-order desktop workstations, servers, and High Performance Computing clusters. Terra Soft made their Yellow Dog Linux distribution solely for Power Architecture, optimizing the distributions for AltiVec and the Cell.Terra Soft was the first to support a variety of Apple computers with Linux pre-installed . When Apple abandoned PowerPC CPUs in favor of the Intel Core chips, Terra Soft was able to concentrate on high-performance computing and the Cell Broadband Engine, working closely with IBM and Sony for the PlayStation 3 products. In 2006, Terra Soft was contracted by Sony to provide a Linux operating system for the PlayStation 3, used by several University researchers as an inexpensive, powerful cluster compute node.Today, Fixstars of Tokyo, Japan carries forward the Yellow Dog Linux and Yellow Dog Enterprise Linux product line with primary focus on heterogeneous, multi-core CPUs such as the Cell Broadband Engine and Nvidia GPU.

Non-volatile memory (NVM) storage is becoming more popular as its performance and cost efficiency improve. Since the performance and characteristics of NVM storage are significantly different from those of HDDs, there are ongoing researches to utilize SSDs more efficiently and effectively. There is a claim that the further improvement of NVM storage performance makes it better to poll a storage device to sense completion of access requests rather than to use interrupts. Polling based storage can expand to become main memory based on NVM storage since there is no complex mechanism required to enable interrupts and access requests are processed one by one. This paper predicts that NVM storage will be in a form of main memory, and proposes constructing a file system directly on it in order to overcome its drawbacks when used simply as main memory. The performance projection of the proposed architecture is that accessing files on such a file system can reduce the overhead introduced by handling block devices. © 2013 IEEE. Source

Active research and development efforts on byte addressable non-volatile (NV) memory technologies, such as STT-RAM, PCM, and ReRAM, have been conducted in recent years. Because they are byte addressable, they can be used as main memory by directly connecting them to CPUs. Because they are non-volatile, they can also be used as storage device. While there were the active researches on their use for either main memory or secondary storage, these researches were conducted independently. This paper presents the memory management methods that enable the integration of main memory and file systems, thus, both main memory and storage are realized on the same byte addressable NV memory. The presented methods construct a file system on NV memory, and memory blocks assigned to files are exported for the use of main memory. We implemented the proposed methods in the Linux kernel, and performed their evaluation. The evaluation results show that the file-based methods can perform comparably to the existing DRAM memory allocator and can maintain the consistency of a file system. © 2013 IEEE. Source

Real time visual tracking by particle filter has been implemented on Cell Broadband Engine in parallel. Major problem for the implementation is small size of Local Store (LS) in SPEs (Synergistic PEs), which are computational cores, to deal with image of large size. As a first step for the implementation, we focus on color single object tracking, which is one of the most simple case of visual tracking. By elaborating to compress the color extracted image into bit-wise representation of binary image, all information of the color extracted image can be stored in LS for 640×480 size of original image. By applying our previous implementation of general particle filter algorithm on Cell/B.E. to this specific case, we have achieved real time performance of visual tracking on PlayStation ® 3 about 7 fps with a camera of maximum 15 fps.

Most of the theories of the solar system formation stand on the assumption that the formation of planetesimals occurs in a transparent (i.e., optically thin) nebula, in which H2O ice is unstable at the formation region of the terrestrial planet due to direct stellar irradiation. However, in the astronomical context, it is confirmed by both observations and numerical models that protoplanetary disks are initially opaque (i.e., optically thick) owing to floating small dust particles, and the interior of the disk is colder than the transparent disk. If planetesimals are formed in the opaque cold nebula, they should be mainly composed of H2O ice, even at the formation region of terrestrial planets. Abundant icy material would help the formation of planetesimals through enhancement of the dust amount. Icy planetesimals start sublimation when the protoplanetary disk gets transparent through clearance of small dust particles. Here, we investigated the consequence of such icy planetesimal formation through numerical simulations of the competition between the sublimation and accretion of icy planetesimals. It was shown that various types of planets ranging from rocky planets to water-ball planets can be formed inside the location of the snow line of a transparent disk depending on the disk mass and the time evolution of disk transparency. We found size-dependent water content of icy planetesimals, which suggests potential difference in the redox state between meteorites and terrestrial planets at the same distance from the central star. © 2010.

While hard disk drive vendors have managed to hit the mythical 10TB barrier, SSD manufacturers are not far behind. In fact, a little known Japanese company, Fixstars, has unveiled a 6TB SSD that can fit in some laptops. What makes it so special is that it's a 2.5-inch model compared to the 3.5-inch drives that are used in traditional computers – that translates into a much higher storage density, in other words, you can pack in more data per unit volume. The SSD-6000M uses 15nm MLC flash memory, providing read/write speeds of up to 540MBps and 520MBps respectively. There are actually bigger 2.5-inch SSDs on the market; in November last year, US-based Foremay outed an 8TB SATA 3 SSD drive, with AmpINC and Novachips already shipping 8TB models. What makes the Fixstars announcement stand out from the pack is the fact that it is a mere 9.5mm thick, thinner than the competition (which is generally 15mm thick). The SSD-6000M will be available towards the end of July for US customers with RoW ones likely to follow shortly after. Fixstars hasn't said how much they will cost but expect these drives to come at a very significant premium. The next big capacity jump is likely to occur at 10TB with Intel and Micron having already committed to such devices over the next few months. Like the aforementioned pair, Samsung on one side and SanDisk and Toshiba on the other will use 3D NAND flash technology to deliver drives that may well surpass the capacity of hard disk drives, albeit at a steep cost.
