- Discussion topic
- How sites are handling Meltdown/Spectre?
Trevor from SDSC mentioned they have updated Kernel patches from vendor and installed with mitigations turned off. SDSC tested and saw 20% decrease in I/O performance with page table mitigation, and 70% decrease with branch mitigation. With those results that is why leaving the mitigation turned off and also with no known exploit known to be used in the wild. Also, new kernel update from RHEL out since the Meltdown/Spectre. RH pulled their firmware updates.
- Open Discussion, as time permits
Shava mentioned XSEDE may be ready to discuss the Globus software status in more detail on next call.
