App hangs with dataspaces

[kshitij-v-mehta]

Trying dataspaces after the recent merge #6 , but seems to hang.

$> ./run-workflow.sh 20 DATASPACES
swift: launching dataspaces_server
Checking for conf:
Conf exists.
swift: launching: ./heat_transfer_adios2
size: 6
swift: launching: stage_write/stage_write
Input stream            = heat.bp
Output stream           = staged.bp
Read method             = DATASPACES (id=3)
Read method parameters  = "max_chunk_size=100; app_id =32767; 
verbose= 3;poll_interval  =  100;"
Write method            = MPI
Write method parameters = ""
Variable to transform   = ""
Transform parameters    = ""
 Process number        : 4 x 3
 Array size per process at first step: 40 x 50
Step    1:
Writing:  filename               size(GB)    io_time(sec)      GB/s

No progress beyond this point.

I don't see heat_transfer connecting to DataSpaces in that output. Is the method attribute set to DATASPACES for the "heat" group? (i.e. is the line uncommented in heat_transfer.xml?)

Thanks, Philip

Yep, I did not modify the xml file! Thanks.

Did you change xml file to use DATASPACES? I had a similar issue like this.
