A few changes have occurred since Blake's work was completed, that
have impacted your tests.<br>
<ol>
<li>rearrangement of the gluex software tree: Used to be that
/home/halld/src pointed to something. Now it should be
/home/halld/sim-recon/src, as I understand it. That is where I
am accessing the gluex software stack. Note that this is not
always up-to-the-minute recent latest build from Dave et.al. If
you need a certain tagged release installed, please let me
know. Otherwise you can install it yourself under the $OSG_APP
directory tree, like I think Blake explains in his howto.</li>
<li>srm tools are used to access the data grid. The data grid is
supposed to be used to store large data files, such as
simulation output and logs, but not small files such as
executable scripts or software build trees. If you are having
problems getting a reasonable response from my srm server,
please forward me the details. Here is what I am getting, at
this moment as I write: 30 seconds of overhead to establish a
srm session and do a simple task -- srm is not supposed to
compete with command-line tools for things like ls, but has high
transfer throughput for large files.<br>

<li>I think that Blake was just forgetting about what tools to use
for what needs. If you want to look at files in local disks on
the server, just a simple remote command like the following will
do. You can see that this one completed in 4 seconds.</li>

<pre wrap="">Hi, Richard.
I don't think 5 pm this evening will work for me. Do you have some time tomorrow? I am generally free until about 6 pm on Tuesdays.
Let me briefly tell you what I'm working on. I used Blake's example code from the wiki to generate a .sub script to generate some pythia events. I get the following error:
/nfs/direct/app/Gluex/eta-pi0/setup.sh line 2: /home/halld/src/BMS/osrelease.pl<a href="http://osrelease.pl"><http://osrelease.pl></a>: no such file or directory
The setup.sh file is the one I need to edit. Blake suggested that the only way to edit files is to use the srmcp command to copy the file to my home directory and then edit it there before copying it back to the grid. When I tried using the srm commands to access grendl, I get errors, but not when I access grinch. I think I am just not quite clear on the structure of the grid. That is something I would like to discuss when we get the chance.
Let me know if tomorrow will work.
Thanks,
Jake

Jake,
I would be available to chat with you this afternoon at 5:00 our time (EST). Will that work for you?
