[Swift-user] Pointer to Swift tutorials for computational science education and research

[Ketan Maheshwari]

Hi Andrew,

Yes, I remember: thanks for getting back on this.

>From the error message and tc.data, indeed it looks like the executable is
provided as absolute path but somehow Swift is looking into system path and
not finding it. One possibility is that the node on which catnap.sh is
running does not have it installed on the path specified in the tc.data.
Can you also check if catnap.sh has the executable bit set. Less likely
that this is causing the issue though.

Also, from the tc.data line it looks like you are using persistent
coasters. Have started the coaster service beforehand and made sure the
service started correctly without any error messages. Could you indicate
more about your cluster. Depending on the type of cluster, it is possible
that we can run Swift in a non-persistent, implicit coasters mode.

Can you also send the Swift generated log for this run.

Thanks,
Ketan
