<div dir="ltr"><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).

Hi<br>
<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>
</div>
<div>Thank you,</div>
