<P><FONT SIZE=2>You might try the clusterit toolkit. It allows you to spawn jobs across several machines quite easily. You can find it on the FreeBSD web site (www.freebsd.org).</FONT></P>

<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> We are trying to move our large sets of batch jobs (several thousand)</FONT>
<BR><FONT SIZE=2>> into a make type environment. We already have a cluster running </FONT>
<BR><FONT SIZE=2>> OpenPBS, but are looking at alternatives to PBS since we have been </FONT>
<BR><FONT SIZE=2>> having problems with hangs and such. I am interested in MOSIX since </FONT>
<BR><FONT SIZE=2>> it seems like it would integrate well with our multiple independant </FONT>
<BR><FONT SIZE=2>> processes model and with make. But I also read in the MOSIX FAQ that </FONT>
<BR><FONT SIZE=2>> java processes don't get migrated. Most of our programs are java </FONT>
<BR><FONT SIZE=2>> code that links in fast native code for algorithms. I am not that </FONT>
<BR><FONT SIZE=2>> familiar with MOSIX and I don't know if migrating processes would </FONT>
<BR><FONT SIZE=2>> even be necessary for us. Ideally I would like to be able to do a:</FONT>
<BR><FONT SIZE=2>> make -j50</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> and run 50 processes at a time. Right now we just have make execute </FONT>
<BR><FONT SIZE=2>> a bunch of qsubs to queue jobs into PBS.</FONT>
<BR><FONT SIZE=2>> We are also looking at Codine/GRD engine.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> So, does anyone have any suggestions? Any experience with MOSIX and </FONT>
<BR><FONT SIZE=2>> make? Would this need the ability to migrate processes? Is MOSIX not </FONT>
<BR><FONT SIZE=2>> a good solution for this type of application? Anyone else setting up </FONT>
<BR><FONT SIZE=2>> make to use a cluster semi-transparently?</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> Thanks,</FONT>
