A Unicore Globus Interoperability Layer
No full textFor several years, UNICORE and Globus have co-existed as approaches to exploiting what has become known as the "Grid". Both offer many services beneficial for creating and using production Grids. A cooperative approach, providing interoperability between Globus and UNICORE, would result in an advanced set of Grid services that gain strength from each other. This paper outlines some of these parallels and differences as they relate to the development of an interoperability layer between UNICORE and Globus. Given the increasing ubiquity of Globus, what emerges is the desire for a hybridised facility that utilises the UNICORE work-flow management of complex, multi-site tasks, but that can run on either UNICORE- or Globus-enabled resources. The technical challenge in achieving this, addressed in this paper, consists of mapping resource descriptions from both grid environments to an abstract format appropriate to work-flow preparation, and then the instantiation of work-flow tasks on the target systems. Other issues such as reconciling disparate security models and file transfer support are also addressed

No full textNeivamyrmex ndeh, new species Figures 118, 132, 143 DIAGNOSIS Male: head and mesosoma blackish brown, gaster reddish brown; head 1.5 × broader than long measured across eyes; smooth and shiny between scattered small punctures; mesosoma blackish brown, entire surface smooth and shining with numerous scattered small punctures, pilosity suberect and dense. Queen and worker unknown. DESCRIPTION Male, measurements (mm) (n = 2): HW 0.86 - 0.91 (0.91); HL 0.55 - 0.58 (0.58); SL 0.39 - 0.41 (0.41); SW 0.15 - 0.16 (0.15); EL 0.305 - 0.306 (0.305); EW 0.23 - 0.26 (0.23); OD 0.09 - 0.10 (0.09); OOD 0.15 - 0.175 (0.175); OMD 0.07 - 0.12 (0.12); OVD 0.20; PW 0.70 (0.70); ML 0.40 (0.40); PL 0.62 - 0.70 (0.70). Indices: CI 156 - 158 (158); SI 49 - 57 (57). Head almost 1.6 × as broad as long. Dorsal margin, in frontal view, concave and rounded at sides; preoccipital carina weak and not forming distinct collar. Free clypeal margin (ventral margin) slightly concave; frontal carina sharp between antennal fossae, but becoming rounded dorsad and curving laterad to form moderate swelling above antennal fossae. Mandible sickle-shaped and acute at apex, about 0.40 mm long. EL 1.3 × EW. OOD about 1.75 × OD. Scape extending to level of upper eye margin, about 3 × longer than broad; subantennal lamella prominent. Mesosoma smooth and shiny, with numerous scattered small punctures. Petiole slightly longer than broad; posterolateral corners rounded; dorsal surface shiny, ventral surface less so. First three segments of gaster smooth and shiny, following segments duller, more distinctly, finely punctate. Subgenital plate longer than broad, somewhat spatulate; apicolateral teeth prominent, median tooth small. Dorsal margin of paramere broadly triangular, margins densely clothed with long flexuous hairs. Volsella with apical fork, dorsal process large and sharp, ventral process blunt and much shorter; inner margin each segment with a minute denticle near fork; numerous long erect hairs along ventral margin. Aedeagus in profile with apically rounded posterodorsal lobe and slightly longer, out-turned sharply pointed posteroventral lobe. Color: head and mesosoma blackish brown, first two gastral segments similar, following segments becoming reddish brown on posterior segments; wings clear brownish. TYPE MATERIAL (Map 5) Holotype: U. S. A., Arizona, Santa Cruz Co., Yanks Canyon (31.42 ° N111.17 ° W), 12 - 15 Aug. 1993 (B. V. Brown and D. Feener). Paratype: U. S. A., Arizona, Cochise Co., Portal, 4800 ft., 4 Aug. 1959 (H. E. Evans). Both specimens in LACM. ETYMOLOGY This species is named for the Ndeh or Apache people of the southwestern United States and adjacent Mexico; the name pronounced approximately “ in deh ”, accenting the second syllable. DISCUSSION This minute species, currently known only from the two specimens cited above, is close in size only to N. baylori and should be readily identifiable on that basis alone. The holotype was taken in a Malaise trap and the Portal specimen was presumably taken at black light. The worker caste of this distinct species is unknown but is certainly likely to be another minute species; possibly it is N. goyahkla, described above. Neivamyrmex ndeh is superficially similar to N. microps, but is significantly smaller and with distinctive genitalic features: the crotch of the apical fork of the volsella has only two barely perceptible teeth that are well removed from each other (see discussion of N. microps).Published as part of Snelling, G.

It differs from that species in the distinctly smaller size in all castes, but most notably the sexual forms. In addition to the smaller size, the males differ from those of N. carolinensis by the relatively shorter and broader, more strongly pyriform, antennal scape. The queen differs from that of N. carolinensis by its smaller size, the presence of a distinct yellow eye spot and a prominent subpetiolar process. These differences are not great, but they are consistent. That workers of N. carolinensis and N. kiowapache are very similar is without question. In view of this similarity we would be hesitant to describe the western form based solely on the worker caste. We are fortunate to have the sexual castes as well and the differences, particularly in size, are consistent and non-overlapping and nonconvergent. The westernmost samples that we have seen of N. carolinensis (from Mississippi and Arkansas) and the easternmost samples of N. kiowapache (from Kansas and eastern Texas) demonstrate no tendency toward intergradation in size or other features. Therefore, for the present we recognize the western form, N. kiowapache, as distinct from the eastern ant, N. carolinensis in the absence of any evidence that they are conspecific</p> <p>Specimens from Nebraska and Louisiana were recorded by M. R. Smith (1942) as N. carolinensis, but we have been unable to locate these specimens and cannot comment with certainty as to their identity. Based solely on distribution, we assume that the Nebraska record will prove to be referable to N. kiowapache. The Louisiana record remains problematic until the specimens can be examined.</p> <p>Rettenmeyer & Watkins (1978) noted the presence of multiple queens in a colony from Kansas identified as N. carolinensis. We have examined samples from this colony and find that they belong to N. kiowapache. In addition to the Kansas material cited in the paper, there were four samples from Georgia and South Carolina. We presume these samples to be true N. carolinensis, but were unable to examine the material during the course of this study, This phenomenon may be common, if not consistent, in both N. carolinensis and N. kiowapache judging from the number of occurrences reported.</p>Published as part of <i>Snelling, G.

SPECIMENS EXAMINED We have 64 records from the United States. DISCUSSION Neivamyrmex minor is certainly one of the more widespread species. Occurring in a wide variety of habitats it is one of the most frequently encountered Neivamyrmex species, and is commonly collected at light. The female castes are currently unknown but, based on ranges, we posit that N. leonardi will prove to be the worker. Although this species has been collected in variety of habitats, it has only rarely been collected in the desert areas of the west. Elevational amplitude ranges from near sea level to about 7000 feet. Automontage images of this ant are available at antweb. org.Published as part of Snelling, G. C. & Snelling, R.

MEXICO, BAJA CALIFORNIA SUR: 8.4 mi W on Ramal a Los Naranjo, at light (LACM). DISCUSSION This species has been previously known only from the type specimen, from an unknown locality in the Mojave Desert. The specimen from north of Adelanto was picked up dead on the ground. Neivamyrmex mojave is evidently nearest to N. microps and superficially looks much like that ant. However it may be distinguished from that species by the non-toothed volsella, and differences in coloration. This species might also be mistaken for N. minor but may be readily distinguished from that species by the small size of the ocelli. The recently described N. nyensis Watkins may be the worker form of this species. Automontage images of this species are available at antweb. orgPublished as part of Snelling, G. C. & Snelling, R.

DISCUSSION This rather large distinctive species is only rarely encountered in the United States and its principal range lies in Mexico and Guatemala. As discussed above, we believe that N. mandibularis is the likely male of N. melanocephalus, but it is also possible that N. mandibularis could be the opposite sex of N. graciellae. One foraging raid of N. melanocephalus was observed. It occurred in full daylight and the workers were taking a variety of small arthropods (B. V. Brown, pers. comm).Published as part of Snelling, G.
