<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><div>Hi All,</div><div><br></div><div>I have a quick question. <br></div><div><br></div><div>It seems the step I was following to run the applications on BG/P with swift is different from the steps suggested by <a href="https://sites.google.com/site/exmproject/development/mosaswift">https://sites.google.com/site/exmproject/development/mosaswift</a>. I was running applications+Swift from head node by just submitting a command below.</div><div><span style="color: rgb(0, 0, 191);"><br></span></div><div><span style="color: rgb(0, 0, 191);">swift -config cf -tc.file tc -sites.file sites.xml ftdock.swift -n=1 -list=pdb.list -grid=10</span></div><div><br></div><div> <span>I didnt start the coaster-service but my site file was using </span><span style="color: rgb(127, 0, 127);">coaster as execution-provider</span> (in site files).
Then Swift allocated some nodes and executed the job and placed the result in my home directory. (<span style="font-style: italic;">My assumption here was coaster-service and workers will be started automatically by swift</span>). <br></div><div><br></div><div>But the above link suggests me to use persistent-coasters, changes to coaster-config files and also to start coaster-service in the head node.<br>
</div><div><br></div><div style="font-weight: bold;"><br></div><div style="font-weight: bold;">Basically I have three questions:</div><div><br></div><div>1) What is the different between Coasters and Persistent-Coasters?</div><div>2) <span>How I was able to run the swift+application without starting the coaster-service, since coaster-service is expected to be started manually (<span style="font-style: italic;">according to the above link</span>) ? Does swift use some other mechanisms to send a job if </span><span> coaster-service is not started explicitly</span><span>?</span></div><div><span>3) How I need to run my experiments in future with MosaStore and Swift ? Should I use </span> Coasters / Persistent-Coasters ?<br></div><div><br><span></span></div><div><span>Thank you</span></div><div><span>Emalayan<br></span></div></div></body></html>
