In this paper we describe how to apply powerful performance analysis techniques to understand the behavior of multilevel parallel applications. We use the Paraver/OMPItrace performance analysis system for our study. This system consists of two major components: The OMPItrace dynamic instrumentation mechanism, which allows the tracing of processes and(More)
Scalability to large number of processes is one of the weaknesses of current MPI implementations. Standard implementations are able to scale to hundreds of nodes, but no beyond that. The main problem of current implementations is that performance is more important than scalability and thus some assumptions about resources are taken that will not scale well.(More)
The c-mos proto-oncogene is the cellular counterpart of the viral oncogene v-mos isolated from Moloney murine sarcoma virus. The c-mos gene locus has previously been assigned to human chromosome 8. By both in situ hybridization and molecular hydridization to sorted chromosome DNA (using a c-mos probe) we have localized the c-mos gene to band 8q11. This(More)
I show, by in situ hybridization, that c-fos is expressed in the nervous system during mouse development. This expression was found to be restricted to specific regions at late stages of development (day 16 postcoitum), particularly to the spinal cord, dorsal root ganglia, and olfactory lobe. The c-fos protein may play a role in the maturation of these(More)
To isolate DNA segments specific to chromosome band 14q11, which has been implicated in a number of human T-cell malignancies, a genomic DNA library was prepared from a variant cell subline of the human lymphoblastic KE37 cell line. This subline (KE37-R) bears a t(8;14) (q24;q11) translocation, and the breakpoint on the resulting chromosome 8q+ has been(More)
A molecular rearrangement of the proto-oncogene c-myc located downstream of the exon III 3' end has been found in a cell line derived from KE37 cell line established from an acute T-lymphoblastic leukemia. This rearrangement resulted from a chromosomal translocation t(8; 14)(q24; q11). Since the 14q11 chromosomal band has been found to be involved in(More)
The c-fos proto-oncogene is the cellular homologue of v-fos identified as the bone transforming gene of the FBJ and the FBR murine osteosarcoma viruses. We show here, using a sensitive in situ hybridization method, that the c-fos proto-oncogene is expressed in the cartilage, bone and tooth forming tissues during mouse development. This result suggests that(More)
