Heuristics are needed to map (match and schedule) tasks onto machines in an HC system so as to optimize some figure of merit. An HC system model is needed to simulate different HC environments to allow the study of the relative performance of different mapping heuristics under different circumstances. This paper characterizes a simulated HC environment by using the expected execution times of the tasks that arrive in the system on the different machines present in the system. This information is arranged in an “expected time to compute” (ETC) matrix as a model of the given HC system, where the entry (i, j) is the expected execution time of task i on machine j. The ETC model is used to express the heterogeneity among the runtimes of the tasks to be executed, and among the machines in the HC system. An exis...

The proposed resource allocation heuristics were implemented on the High Performance Distributed Computing Program's (HiPer-D) Naval Surface Warfare Center testbed. The goal of this study is to design static resource allocation heuristics that balance the utilization of the computation and network resources while ensuring very low failure rates. A failure occurs if no allocation is found that allows the system to meet its resource and quality of service constraints. The broader goal is to determine an initial resource allocation that maximizes the time before run-time reallocation is required for managing an increased workload. This study proposes two heuristics that perform well with respect to the load-balancing and failure rates. These heuristics are, therefore, very desirable for HiPer-D like systems where low failure rates can be a critical requirement.

It is triggered by a broad spectrum of "fused oncoproteins" which are entailed in the disease refractoriness. In Pakistan the molecular diagnosis for leukemia is still in its infancy, as the diagnosis does not efficiently encompass a wide range of the fusion transcripts which are generated as a result of exclusive genomic rearrangements. Two point mutations C944T and T932C of ABL gene were detected which cause complete/partial imatinib resistance with limelight NUP98-LEDGF fusion transcript.

The present study was done to improve the regeneration of two commercially grown wheat varieties Kohsar and Khyber-87. Mature embryos were used as explants. Five different concentrations of 2,4-D; 2, 2.5, 3, 3.5 and 4 mg/L were used for callus induction. For regeneration, initially different concentrations (0.1 to 0.2) of IAA (indole-3-acetic acid) and BAP (6-benzylaminopurine) were experimented. The best combination of these hormones that is, 0.1 mg/L IAA and 0.5 mg/L BAP were further subjected to experimentation along with different concentrations of kinetin; 0.1, 0.2, 0.3, 0.4, 0.5 and 1 mg/L. Maximum calli of Kohsar (83.3%) was obtained at 3 mg/L 2,4-D whereas for Khyber-87 maximum callus induction (71.70%) was obtained at 3.5 mg/l 2,4-D. The maximum regeneration of both Kohsar and Khyber-87 (80.5 and 62.2%, respectively) were obtained at the combinations of 0.1 mg/L IAA, 0.5 mg/L BAP and 0.5 mg/L kinetin.

This study is the first report on peanut regeneration from Pakistan using four commercially released peanut varieties, that is, Golden, BARI-2000, BARD-479 and BARD-92. Longitudinally, halved cotyledons with removed embryos were employed as explants. Among various tested combinations of BAP and NAA, the best combination was 4 and 0.1 mg/L respectively. BARI-2000 proved to be the best responsive variety for in vitro regeneration in terms of number of shoots/explant (133.3%) and number of rooted plants/explant (124.99%). The optimized protocol, which is the first one in the country, would be used to incorporate important traits in future breeding programmes of peanut in Pakistan.

Twenty-two patients having persistent generalized or ocular myasthenia gravis referred to our department by neurologists and general physicians, partially or not responding to medical treatment with or without thymoma, were included in the study. Those who were not fit for anaesthesia were excluded. Preoperatively 2 to 3 sessions of plasmapheresis were done and each patient was given anti myasthenia gravis treatment. Clinical staging was done by Modified Osserman classification. Median sternotomy approach was used. Outcome was assessed on the basis of remission of disease in different Osserman groups. All patients were followed for a minimum of 6 months. Out of 22 patients, 16 (72.7%) were females and 6 (27.2%) males. Mean age at presentation ...

An important research problem in these environments is how to assign resources to applications (matching) and order the execution of the applications (scheduling) so as to maximize some performance criterion without violating any constraints. This process of matching and scheduling is called mapping. 1Howard Jay Siegel holds a joint appointment in the Computer Science Department as well. 2Albert I. Reuther is currently with
