| sf-slack2 | <butta> Are others seeing that check rr_graph now takes a very long time with the newest symbiflow-arch-defs? Last week check_rr_graph was taking 5 seconds and its now taking 95 seconds. | 14:34 |

| sf-slack2 | <acomodi> @butta Could it be due to this merged PR? https://github.com/SymbiFlow/symbiflow-arch-defs/pull/858 | 14:48 |
| tpb | Title: cmake: update VTR and add new command line options by acomodi · Pull Request #858 · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com) | 14:48 |
| sf-slack2 | <acomodi> Try to use this commit 3948971c48cd3ba1f1ba850bd444df48dbc371a8 | 14:49 |
| sf-slack2 | <butta> @acomodi It's not an issue for us since were commenting out the rr_graph check in source built vpr. Just wondering if it was a known issue. | 14:50 |
| duck2 | does it take 95 seconds _with_ suppressed warnings? | 14:52 |
| sf-slack2 | <butta> Yes that's with suppressed warnings | 14:53 |
| sf-slack2 | <acomodi> @duck2 I was thinking that it might be the cause | 14:53 |
| sf-slack2 | <butta> Although I'm writing to a log file on a harddisk, could try dumping to /dev/null | 14:53 |
| sf-slack2 | <acomodi> @butta Could you try to launch VPR without the `--suppress_warnings` line? | 14:54 |
| duck2 | acomodi: it used to take 140 seconds with the warnings on. I wonder if it's due to printing/logging or due to the execution path being broken so many times. | 14:54 |
| sf-slack2 | <butta> @duck2 interesting, with warnings on it only took 5-10 seconds for us | 14:56 |
| sf-slack2 | <acomodi> @butta So it's confirmed that `suppress_warnings` is indeed drastically increasing run-time? | 14:58 |
| *** proteusguy has quit IRC | 14:59 | |
| duck2 | acomodi: yes i guess. I took another look at http://duck2.lt/warnings.txt and noticed that check_rr_graph completed in normal time when warnings were directed at a log file. 140 seconds was when it was printing to a terminal. | 15:01 |
| sf-slack2 | <acomodi> Ok, IMO, being the warning suppression optional, this is not a huge issue | 15:06 |
| sf-slack2 | <acomodi> I will check if there is a way to bring warning suppression to acceptable run-time though | 15:06 |
| sf-slack2 | <butta> Just ran some tests. Writing log file to our HDD array took 85 seconds to create the device. Writing the log file to a local SSD took 10 seconds to create the device. Printing warning to console took 12 seconds to create device. | 15:13 |
| sf-slack2 | <acomodi> @butta Well, that is good news. Thanks for the information. I guess then that if you usually use the HDD instead of the SSD it would be better not to write the suppressed warnings log-file | 15:17 |

| litghost | acomodi: I think it makes sense to make the suppressed warning file optional (e.g. don't write them at all) | 16:57 |
| sf-slack2 | <acomodi> litghost: makes sense | 17:06 |
| *** kraiskil has quit IRC | 17:33 | |
| sf-slack2 | <butta> I agree with litghost, we would appreciate having the option to not write to file | 17:45 |

| mithro | duck2: How's that rr_graph.xml parser going? | 21:30 |
| duck2 | mithro: I'm looking more into updating the schema for arch.xml so that I fully know which features could be needed. There are many features of XSD which can aid in fully validating the file. For instance, segment wire_switches have to correspond to switch names. XSD>1.0 has a <xs:keyref> tag for that. I'll just add comments about these, then let's | 21:35 |
| duck2 | see if I'll be able to implement them | 21:35 |
| mithro | duck2: As you come across these ideas, can you log an issue about them? | 21:38 |
| duck2 | mithro: ok | 21:40 |
| mithro | duck2: Also need to log those github issues... | 21:44 |
| duck2 | mithro: right. I looked at the schemas first so that I can see if we need more features than what is used in the current ones. | 21:48 |
| mithro | duck2: I added some issues to your repository... | 21:53 |
| duck2 | mithro: checking them now | 22:00 |
