  1. CIS669 Distributed and Parallel Processing Spring 2002 Dr. Yuan Shi Lecture 4

  2. Synergy Architecture • Static Daemons: pmd + cid • Dynamic daemons: tsh + fah • Language Injection Library: libsng.a • Runtime components: prun + prun x -debug + pcheck • CSL compiler (Configuration Spec. Lang.) • DAC(Distributed Application Controller) • Cds –f (check daemons) • Other Tools • Host management: shosts, chosts, addhost, delhost, dhosts • Failure detection: fdd • Daemon check: cds

  3. Parallel Processing Environment • Cluster(s) of networked computers • ~/.sng_hosts holds all known and/or useable machines. • SNG_PATH points to synergy root on the compiling host. • /synergy/bin in local command search path. • A real ~/bin directory on each host. • Pmd/cid started on each host.

  4. Application Creation Process Step 1 Step 2 Step 3 ap1.c apps.csl %prun/pcheck ap2.c tsh conf cc/gcc cid cid cid fah cid dac libsng.a ~/bin/ap1…

  6. Applications • Computing intense applications • IO intense applications

  7. Future Research • Stateless processing • Distributed stateless processing (transaction) • Fault tolerant cluster research
