With the objective of minimizing the total execution time of a parallel program on a distributed memory parallel computer, this paper discusses how to nd an optimal supernode size and optimal supernode relative side lengths of a supernode transformation (also known as tiling). We identify three parameters of supernode transformation: supernode size,(More)
With the objective of minimizing the total execution time of a parallel program on a distributed memory parallel computer, this paper discusses the selection of an optimal supernode shape of a supernode transformation (also known as tiling). We assume that the communication cost is dominated by the startup penalty and therefore, can be approximated by a(More)
IPv4 address space is almost exhausted. Usage of IPv6 address by client end hosts is limited due to small percentage of domain names that have IPv6 address. This paper presents practical testing in ISP that gives its users IPv6 addresses and provides them transparent access to both IPv4 and IPv6 Internet locations. DNS64/NAT64 translation mechanism is used(More)
This paper discusses the problem of program execution time measurement. Program execution time measurement is problematic because the conventional measurement method, based on the real-time clock interrupt counting, is prone to inherent errors. These errors are caused by discrete nature of real-time clock interrupts and by the overhead of clock interrupt(More)
