Hi, We have some problems while running Sequest Cluster. Our cluster is configured as follows: Master Node: Dell Precision 2670, with 2 Xeon 2.4GHz CPUs and 2 gb of RAM Microsoft Windows 2003, with Service Pack 1 Slave Nodes 1 to 8: Dell Precision 2670, with 2 Xeon 2.4GHz CPUs and 2 gb of RAM Linux Fedora Core 4 We are using BioWorks version 3.2 SR1. The first problem we have is when we start the PVM (by clicking "Start PVM" in the Cluster Manager), we always get the following error for Node 2, even if "Cleanup Nodes" has been clicked prior to starting PVM: "Error connecting to the stderr server port!error in receive on socket: Socket shutdown by remote." three times the same line When starting PVM, node2, node6 and node 7 are not started and the message states we started only 6 hosts. Here is the pvml.proteomics file contents: (joel2 is the name of the master) [t80040000] JOEL2 (192.168.66.250:1073) WIN32 3.4.3 [t80040000] ready Wed May 24 11:59:36 2006 [t80040000] startack() host node2 expected version, got "" [t80040000] startack() host node4 expected version, got "" [t80040000] startack() host node7 expected version, got "" [t80040000] [t80001] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] [t80002] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] [t100001] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] [t100002] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] [t180001] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] [t180002] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] [t1c0001] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] [t1c0002] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] [t240001] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] [t240002] /usr/share/pvm3/bin/LINUXI386/sequest27_slave: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory [t80040000] loclinput() read: 10054 [t80040000] loclinput() marking t40003 dead Do you have any suggestion ?
