There are few questions taking into account incoming Barcelona ;-) 1) Why taskset possibilities are not appropriate for using at rsh issuings from MPI implementations ? BTW, did somebody install taskset, i.e. 1.5.0 schedutils 1.5.0 or util-linux-2.13 under x86-64 OpenSuSE 10.1 or 10.2 ? 2) What is known about RDTSC synchronization between CPU cores in modern Linux kernels (especially I'm interesting in OpenSuSE :-)) ? I heard some time ago that at least some Fedora kernels performed like synchronization. Yours Mikhail Kuzminsky Zelinsky Institute of Organic Chemistry Moscow
