may be causing some incompatibilities. Can you try out the RPM below to see if that’s the resolution? We’re also looking into this on our end.</span></p>

Regarding your questions:</span></p>
<ol start="1" style="margin-top: 0in; margin-bottom: 0in;">
<li style="font-family: "Aptos", sans-serif; font-size: 10pt; margin: 0in;"><span style="font-size: 11pt;">Yes, we are hoping to have MVAPICH 4.0 released within the month.</span></li><li style="font-family: "Aptos", sans-serif; font-size: 10pt; margin: 0in;"><span style="font-size: 11pt;">We have unified redundant envs (like having separate envs for HIP and CUDA) and made naming conventions more consistent for our CVARs. So yes, replace
that with MVP_ENABLE_GPU</span></li><li style="font-family: "Aptos", sans-serif; font-size: 10pt; margin: 0in;"><span style="font-size: 11pt;">Some of these are done in the netmod layer now. You can set IB devices with “UCX_NET_DEVICES=mlx5_0:1” and “UCX_SOCKADDR_TLS_PRIORITY=rdmacm” (rdmacm
may require a new rpm with --with-rdmacm ucx configure flag, I will update the website rpms to allow for this if it passes our testing). MVP_HOMOGENEOUS_CLUSTER’s equivalent is irrelevant now, performance is good regardless of this flag.</span></li></ol>

<p style="margin: 0in; font-family: "Aptos", sans-serif; font-size: 10pt;"><span style="font-size: 11pt;">Hello,</span></p>
<p style="margin: 0in; font-family: "Aptos", sans-serif; font-size: 10pt;"><span style="font-size: 11pt;"> </span></p>
<p style="margin: 0in; font-family: "Aptos", sans-serif; font-size: 10pt;"><span style="font-size: 11pt;">I downloaded the MVAPICH-Plus 4.0 RPM from the following link:</span></p>

but I encountered an issue when trying to unpack it using cpio. The process failed with the error:</span></p>
<p style="margin: 0in; font-family: "Aptos", sans-serif; font-size: 10pt;"><span style="font-size: 11pt;"><br>
cpio: premature end of file</span></p>
<p style="margin: 0in; font-family: "Aptos", sans-serif; font-size: 10pt;"><span style="font-size: 11pt;"> </span></p>
<p style="margin: 0in; font-family: "Aptos", sans-serif; font-size: 10pt;"><span style="font-size: 11pt;">I have no issues unpacking other RPMs, so it seems this file might be corrupted. Could you please check and confirm?</span></p>
