RAM disk

Commodore has announced a 512K. memory expander for the 128, which would be connected through this port. The additional memory is addressable in 64K blocks and can be set up to act as a RAM disk—allowing lightning-speed saving and loading. Of course, any programs would have to be transferred... 

When Windows runs out of memory, hard disk space, or both, we say it has run out of system resources. Windows 3.1 has an About window (in the Windows Program Manager screen, select Help > About) that can be used to check the amount of available system resources (see Figure 10.1). For optimal Windows performance, the available system resources should be above 80 percent. If they are below 80 percent you will need to add RAM, disk space, or both. 

RAM disk An area of memory managed by a special device driver and used as a simulated disk. Anything stored on a RAM disk will be erased when the computer is turned off therefore, the contents must be saved onto a real disk.

The Pascal code was updated to handle four channels. To follow the inspection speed all raw measuring data were captured and stored in the computer. All data for one coil could be stored in the computer memory (RAM) and transferred to the disk before inspection of the next coil. Evaluation of the data could be performed on-line or later using a special evaluation program. 

SCREEN will run on an IBM-PC compatible personal computer with at least 2S6K of RAM. The program will run with or without a math coprocessor chip. Execution time will be greatly enhanced with a math coprocessor chip present (about a factor of S in computer time) and will also benefit from the use of a hard disk drive.

Minimum computer requirements to run THERdbASE are a 486 CPU, IBM or clone, at leasi 8 MB of RAM, at least 40 MB of disk space, color VGA monitor, a mouse, Microsoft Windows. v I To install THERdbASE, execute the File/Run option from within Windows and specify SETUP.F.XE found in the THERDCD directory. This program leads you through the installation. Updates foi THERdbASE can be obtained over the World Wide Web from the Harry Reid Center for Environmental Studies at the University of Nevada, Las Vegas (http //www.eeynre. -hrc, nevada.edu),... 

The purpose of interfacing instruments with computers is to enable raw analytical data to be collected as it is produced, then processed, stored and displayed or printed out. This may be accomplished as it is gathered, i.e. in real-time, or at some later time, i.e. post-run. Complete chromatograms or spectra can easily be stored in the main memory or RAM or transferred to disk. The immense storage capacity of mainframe computers can be used to provide large libraries of data (data banks) for future reference. 

Peaks are identified from absolute or relative retention times by comparison with data from previously run standards stored in RAM or in libraries on disk. To take account of the variability of retention times from successive runs, retention time windows are used. These are defined as being /R x% for a standard, the unknown being positively identified if its retention time falls within the specified range. The size of the window can be varied by the user to conform with the degree of certainty required. Reference peaks can be selected for the calculation of relative retention times or as internal standards in quantitative analysis (pp. 9, 114). 

The minimal hardware requirements, which are certainly adequate for all items discussed here, are an IBM or IBM-compatible PC equipped with at least 640 K RAM, a single floppy disk drive, at least a 40-Mbyte hard disk drive, a CD-ROM drive, a VGA color monitor, and a printer. The basic point here is that hardware requirements are minimal and readily available. In the case of the laser disk products, a laser disk drive and high resolution (VGA) monitor are also required. 

We analyze our images with CellProfiler installed on a Linux cluster to speed up this calculation-intensive process. The cluster is a 17-node cluster (1 master node, 16 compute nodes). Each node has 8 cores with 2.26 GHz and 48 GB of RAM. The master node shares 24 TB of disk space out to the compute nodes over NFS.
