topic ScaLAPACK functions in the MKL and Ethernet network in IntelĀ® oneAPI Math Kernel Library

Hello.<BR />In our class there are 20 computers, Intel Core 2 Duo in each. They are interconnected by simple 100Mbit Ethernet network using one Ethernet switch and twisted-pair.<BR />The question is: is it reasonable to use ScaLAPACK functions (e.g. pdgetrf) at this network and 20 computers? Or I have to use just LAPACK functions (e.g. dgetrf) at single computer?<BR />Thanks!Mon, 12 Jul 2010 12:23:23 GMTalienff2010-07-12T12:23:23ZScaLAPACK functions in the MKL and Ethernet network

Hello,<DIV>depends the task size. if the task size match with RAM available on single computer then please use Lapack version of dgetrf if not then -ScaLapack.</DIV><DIV>--Gennady</DIV>Mon, 12 Jul 2010 12:32:08 GMThttps://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/ScaLAPACK-functions-in-the-MKL-and-Ethernet-network/m-p/781275#M1478Gennady_F_Intel2010-07-12T12:32:08ZScaLAPACK functions in the MKL and Ethernet network

Thanks for your answer!<BR />Yes, the taks's data can be stored in one RAM on single computer.<BR /><BR />Another question - is there any solution (may be not Intel :)) that will yield some performance in such Ethernet network?<BR />Mon, 12 Jul 2010 12:41:05 GMThttps://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/ScaLAPACK-functions-in-the-MKL-and-Ethernet-network/m-p/781276#M1479alienff2010-07-12T12:41:05Z
