store them, and evaluate a 1 ( 3 ) +... + a m ( 3 ) , and so on. When we reach the point when the accumulated roundoff errors in the a n (h) get too big, we reset t 0 to the value of a Gram point near t 0 and recompute the a n . Since the recomputation of the a n would be very infrequent in computations such as that aimed at numerically verifying the RH for a large set of consecutive zeros (where Z(t) is evaluated at all Gram points), the running time of the algorithm would be dominated by the time to compute the component by component product c = (c 1 , . . . , c m ) = (a 1 b 1 , . . . , a m b m ) of two complex vectors a = (a 1 , . . . , a m ) and b = (b 1 , . . . , b m ) and then evaluate the complex sum c 1 +... + c m . These operations are vectorized automatically by the CrayX-MP Fortran compiler, and for m = 10 4 require only about 0. 8 × 10 − 3 seconds, which would yield a program running about 4 times faster than that described in Section 3. Such a program has not been implemented due to the large storage requirements, which would not have allowed computations with zeros around the 10 12 -th zero. However, for verifying the RH around the 10 10 -th zero such a Fortran program ought to be practical and, since most of the computation there involves evaluating Z(t) at Gram points, it would probably run about 3 times faster on the CrayX-MP than the program described in  run on the Cyber-205. Some test runs performed on the Cyber-205 by H. te Riele have shown that the ideas described above appear to lead to algorithms that are faster than those of  on that machine as well.
1. Advances in Technology. The factoring group at Sandia National Laboratories [12, 13, 14] has used the quadratic sieve factoring method on a Cray-1 computer and a Cray XMP computer to obtain the original Ten "Most Wanted" Factorizations. Wunderlich [46, 47, 48] has programmed the continued frac- tion factoring method on various parallel processors. te Riele has programmed the quadratic sieve algo- rithm on a Cyber 205. Young and Buell  used a Cray-2 to determine that the twentieth Fermat number is composite. They checked this calculation with a Cray XMP.
Given the basic mp int structure, an initialization routine must first allocate memory to hold the digits of the integer. Often it is optimal to allocate a suffi- ciently large pre-set number of digits even though the initial integer will represent zero. If only a single digit were allocated, quite a few subsequent reallocations would occur when operations are performed on the integers. There is a trade– off between how many default digits to allocate and how many reallocations are tolerable. Obviously, allocating an excessive amount of digits initially will waste memory and become unmanageable.
Currently, RP can instantiate exactly one Scheduler compo- nent per Agent. The Scheduler is compute (and communica- tion) bound: the algorithm searches repeatedly through the list of managed cores; core allocation and de-allocation are handled in separate, message driven threads. Figure 6 (top) shows how the component performs in allocating cores to a set of units for 4 different pilot sizes. The declining rate is explained by the algorithm and the implementation of the scheduler, as the scheduler needs to search further and further when more cores have been allocated to units. In Figure 6 (bottom) we show the same workload for the scheduler, but the results now also include the unscheduling of units and the freeing of the cores. We do not observe the slope from Figure 6 (top) anymore as the activity now becomes limited by the contention on the lock on the datastructure by both the scheduling and the unscheduling. The process of spawning and managing application tasks is central to the Agent’s Executor component. Figure 7 shows
Here, we describe our overall RV observational campaign and our analysis methodology. Details on individual systems are given in Section 4. We observed K2-27, K2-32, K2-39, and K2-108 using the High Resolution Echelle Spectrometer ( HIRES; Vogt et al. 1994 ) on the 10 m Keck Telescope I. We collected spectra through an iodine cell mounted directly in front of the spectrometer slit. The iodine cell imprints a dense forest of absorption lines which serve as a wavelength reference. We used an exposure meter to achieve a consistent signal to noise level for each program star, which ranged from 100 to 130 per reduced pixel on blaze near 550 nm. We also obtained a “ template ” spectrum without iodine.
To launch an application interactively, the user enters the aprun command, specifying the application executables and the compute node resources they require. The aprun client sends the request to the apsys server, which forwards it to the apsched agent running on a service node. The apsched agent gets the compute node placement list, reserves the nodes needed for the application, and relays the placement list to aprun . On Cray XT4 and Cray XT5 compute nodes, support for non-uniform processing element (PE) placement is supported. This means that apsched will attempt to place the maximum amount of PEs per computer node. This potentially improves performance by allowing systems with both types of compute blades to exploit all resources rather than leave some nodes under-utilized. The aprun client then sends the placement list and the executable binary data to the apinit daemon running on the first node assigned to the application.
As on JUQUEEN, results from three runs performed on the Cray XE6 are shown in Figure 2: One with SDC+PMG and no temporal parallelization, one small run of PMG+PFASST using as many cores for PMG as are necessary to saturate it for the coarse problem (green line, square markers) and one large run, using the number of cores cor- responding to the saturation limit of PMG for the fine problem (red line, diamond mark- ers). Furthermore, a serial run of PMG with the coarse level spatial discretization is done for comparison (not shown here). The dashed line indicates ideal speedup.
Sometimes deals hinge on your ability to get the right document to the right person within moments. The Ricoh MP C2003/MP C2503 lets you scan color or black-and-white originals to shared folders, PC media cards and other locations, so they can be shared with anyone, anywhere. It includes Distributed Scan Management (DSM) to automate many scanning functions and to create a set of rules for user permissions, file types and more. Plus, it offers an optional embedded OCR scanning feature so you can create searchable and editable PDF files for advanced indexing and retrieval of your scanned documents.
Abstract— Cray Management Services is quickly evolving to address the changing nature of Cray Systems. NodeKares adds advanced features to support gang scheduling, reservation and application level health checking. Reservation level node health improves node availability by allowing administrators to move tests between application and reservation boundaries. Lightweight Log Manager provides more complete and standardized log collection. Configuration hooks allow administrators to extend Lightweight Log Management for third-party logs, and to aggregate logs to external log hosts. Modular xtdumpsys will provide an extensible framework for system dumping. Administrators can quickly extend plugins, and define plugin sets that allow them to target data gathering and collection based on classes of failures. Resource Utilization Reporting provides a scalable, extensible framework for data collection, including power management, GPU utilization, and application resource utilization data. This paper presents these new features: covering configuration and benefits.
With the use of molecular diagnostics, co-detection with other viral/bacterial pathogens has been commonly identified in Mp positive patients. Nonetheless, this study confirms that the clinical features and severity of Mp mono-detected patients are relatively similar to those co-detected with viral and/or bacterial pathogens. Thus, we speculate that a large proportion of CAP pa- tients may be infected with a major pathogen of pneu- monia (i.e. Mp ) and tend to have a colonization of other pathogens in respiratory tract . Furthermore, it is also possible that the viral or bacterial pneumonia pa- tients may have a serologic evidence of past MP infec- tion (IgM positive) or PCR positive (colonization).
For fluorescence-activated cell sorting (FACS) quantifica- tion of nanoART uptake by MP, monocytes or MDM were exposed to rhodamine- or DiD-labeled nanoART for 12 hours and washed three to five times with PBS to remove free nanoART. MP were then fixed by incubation in 1% para- formaldehyde for 20 minutes, washed, resuspended in PBS, and analyzed by FACS using a FACScan flow cytometer (BD Bioscience, San Jose, CA). The mean fluorescence channel and mean number of rhodamine-positive cells were derived using CellQuest software (BD Bioscience). To determine the levels of nanoART in MP and HBMEC following MP-endothelial communication, monocytes loaded with rhodamine- or DiD-labeled nanoART were cocultured for 2–4 hours with HBMEC (unlabeled or DiD-labeled), then washed three to five times to separate monocytes from endothelial cells. HBMEC and monocytes recovered from cocultures were then fixed by incubation in 1% paraform- aldehyde for 20 minutes, washed, resuspended in PBS, and analyzed by FACS. The mean fluorescence channels and mean number of rhodamine-positive cells (monocytes), DiD- positive cells (HBMEC), and HBMEC double positive for rhodamine and DiD were derived using CellQuest software (BD Bioscience). For all FACS analyses, each experimental condition was performed in triplicate.
