Trimaran is an integrated compilation and performance monitoring infrastructure. The architecture space that Trimaran covers is characterized by HPL-PD, a parameterized processor architecture supporting novel features such as predication, control and data speculation and compiler controlled management of the memory hierarchy. Trimaran also consists of a full suite of analysis and optimization m...

This paper studies the improvement of performance and execution time of a single compute-node in a Beowulf cluster. We want to implement a load balancing approach through the Linux scheduler which improves the performance and execution time of High Performance Linpack (HPL) benchmark. We compare the performance and execution time when spawning processes for two processing cores in a local proce...

This paper describes the design and evaluation of an instructional module for teaching/learning Fourier spectral analysis, with emphasis on biomedical applications. The module is based on the principles of “How People Learn” (HPL) as embodied in the Legacy cycle. This cycle is a particular instantiation of problembased learning and includes components explicitly aimed at providing context and m...

While recognition of the advantages of heterogeneous computing is steadily growing, the issues of programmability and portability hinder its exploitation. The introduction of the OpenCL standard was a major step forward in that it provides code portability, but its interface is even more complex than that of other approaches. In this paper we present the Heterogeneous Programming Library (HPL),...

This paper applies a Hybrid MPI-OpenMP programming model with a thread-to-thread communication method on a cluster of Dual Intel Xeon Processor SMPs connected by a Gigabit Ethernet network. The experiments include the well-known HPL and CG benchmarks. We also describe optimization techniques to get a high cache hit ratio with the given architecture. As a result, the hybrid model shows performan...

OBJECTIVE to quantify placenta-specific RNA in plasma of women carrying foetuses with intrauterine growth restriction and pregnant women with normal pregnancies. METHODS 8 pregnant women with foetuses with intrauterine growth restriction were studied as well as 18 women with uncomplicated pregnancies in the third pregnancy trimester. Total free RNA was quantified in maternal plasma by spectro...

The ultrastructure of placental bed giant cells in early human pregnancies of 7-12 weeks gestational age is described. Their nature and function was further characterized by confocal immunofluorescence microscopy of paraffin sections labelled for cytokeratin, gap junction connexins (CX) 32 or 43, and placental hormones, alpha-human chorionic gonadotrophin (alpha-HCG) and human placental lactoge...
