<div>Thanks for the speedy response.</div>
<div>We are currently building 0.5.0 from source.</div>
<div><br>
</div>
<div>I have three additional questions;</div>
<ol>
<li>Is there a float -> int function? I crating a workaround by casting float -> string -> (parse on decimal) string -> int. It is wasteful, and it only works when there is no exponential component.</li><li>Is there a single, comprehensive place to read about the '@' directives? For example, I cannot determine the difference between '@dispatch=WORKER' and '@dispatch=LEAF' from the documentation I have found.</li><li>Is a roadmap posted online? It is relevant to my project to know about this programming-model's direction. It would be particularly helpful to know when 0.6.0 and 1.0 are planned for release and what will be added to the implementation.</li></ol>
<div>Thank You, </div>

<div>I just wanted to add that if you built the release from source you can safely comment out the offending line (line 2178 of tcl-adlb.c, I believe, if you are using the exm-0.5.0 release). As Justin said, this made it into the release on accident and doesn't
have any useful purpose.<br>

Sorry- that message is a debugging line that unfortunately made it into the release. It is already removed from our trunk and will not be in the next release- you can just remove it from your source.
<br>
<br>
I will fix the blob doc issue now but feel free to post any additional questions here in the meantime...<br>

<div>Hello,</div>
<div><br>
</div>
<div>I am writing a program in Swift/T that generates blob objects inside a leaf function. Binary data is generated with a Swig-wrapped C function, and the blob construct is produced by making a list out of the pointer and length in the Tcl wrapper.</div>
<div><br>
</div>
<div>Here is a sample from my Tcl script:</div>
<div><br>
</div>
<div>
<div>proc c_initVect { s o } {</div>
<div><span style="white-space:pre-wrap"></span>set len [ expr $s * [blobutils_sizeof_int32] ]</div>
<div> set ptr [ blobutils_malloc $len ]</div>
<div> initVect [blobutils_cast_to_int_ptr $ptr] $s $o # C leaf function</div>
<div><br>
</div>
<div> return [ list [ blobutils_cast_to_int $ptr] $len ] # creating the blob</div>
<div>}</div>
</div>
<div><br>
</div>
<div>When I run the program with this snippet, my output fills with 'uncache_blob' messages.</div>
<div><br>
</div>
<div>Here is an example:</div>
<div>uncache_blob: 67376368 4000 3uncache_blob: 67380384 4000 4</div>
<div>Which is the output from a program that generates 2 blobs with the function above.</div>
<div><br>
</div>
<div>The output is automatically generated by the runtime, and I have no control over when blobs are uncached.</div>
<div><br>
</div>
<div>I've traced that output to ADLB_Local_Blob_Free_Cmd function in src/tcl/adlb/tcl-adlb.c</div>
<div><br>
</div>
<div>For programs that allocate a large number of blobs, the output from the runtime becomes overwhelming, and I am starting to think my snippet is generating blobs incorrectly. So far, the only example I can find that generates blobs that are returned to Swift/T
is a the fortran example from the leaf functions guide (Section 3.4 <a href="http://www.mcs.anl.gov/exm/local/guides/leaf.html" target="_blank">
www.mcs.anl.gov/exm/local/guides/leaf.html</a>). There is a promising link in Section 3.3.3 of the leaf guide that explains blobs, but when I click on it I get a 403 error.</div>
<div><br>
</div>
<div>Is anyone aware of additional examples or tutorials that explain how to generate and manage blobs in Swift/T.</div>
<div><br>
